Drayton Wiser 1-Channel 2nd Generation HubR CCTFR6311G2D | Smart Heating Controller for Combi Boilers | OpenTherm | ZigBee
The Drayton Wiser 1-Channel 2nd Generation HubR (CCTFR6311G2D) is the smart heating controller for properties with a combi boiler — controlling one heating channel via OpenTherm modulating control or relay switching, and acting as the central hub for the entire Wiser smart heating and smart home ecosystem. Installed in place of a conventional room thermostat or programmer, it connects to the boiler via fixed wiring (230V) and communicates wirelessly with Wiser room thermostats, radiator thermostats (TRVs), and smart home devices via a ZigBee mesh network operating independently of home Wi-Fi. The hub itself connects to the internet via 2.4GHz Wi-Fi, enabling remote control through the Wiser Home app (iOS and Android) and voice control via Amazon Alexa and Google Assistant. Fully Boiler Plus compliant. Dimensions 150.8 × 94 × 30.3mm. 3-year manufacturer's guarantee.
⚠ For Combi Boilers Only — Conventional/System Boiler Users See Below
The 1-Channel HubR controls a single heating circuit with no separate hot water channel — correct for combi boilers, which provide hot water on demand without a cylinder. If your property has a conventional or system boiler with a hot water cylinder, choose the 2-Channel HubR (CCTFR6312G2D) which provides 1 × Heating + 1 × Hot Water. For large properties requiring dual heating zones plus hot water, see the 3-Channel HubR (CCTFR6313G2D).

⚠ Fixed Wiring — Qualified Installation Required — The HubR connects via fixed mains wiring (230V) and must be installed by a competent electrician in accordance with BS 7671 and Part P of the Building Regulations. It cannot be connected via a plug socket. The hub occupies the position previously held by the room thermostat or programmer — existing L, N, and E wiring plus boiler/heating circuit switching wires are connected directly to the hub terminals. A Wiser Room Thermostat or Temperature/Humidity Sensor is required to complete the heating control loop.

Features & Benefits
✔ OpenTherm — Modulating Boiler Control
OpenTherm is an open communication protocol that allows the Wiser hub to communicate directly with a compatible boiler's control board — telling the boiler how hot to run (the flow temperature setpoint), not just when to fire and when to stop. Rather than simple on/off switching where the boiler fires at full temperature until the room thermostat is satisfied, OpenTherm allows the boiler to modulate its output continuously — running at the lowest flow temperature sufficient to maintain comfort. This reduces cycling, lowers average flue losses, and makes the boiler operate in condensing mode for a greater proportion of its run time. On most OpenTherm-compatible condensing boilers, this results in measurable fuel savings compared to relay control alone.
✔ ZigBee Mesh — Independent of Home Wi-Fi
The ZigBee mesh network is the wireless backbone that connects all Wiser thermostats, radiator TRVs, and smart home sensors to the hub — and it operates on a completely separate radio channel to home Wi-Fi. This has two important practical consequences: the Wiser devices are unaffected by Wi-Fi router reboots, congestion, or password changes; and every Wiser device on the network automatically acts as a mesh relay for other devices, extending range organically as more devices are added. A room in a corner of the house that struggles with Wi-Fi signal may be perfectly reachable via the mesh. The hub itself uses 2.4GHz Wi-Fi only for its internet connection to the Wiser Home app and cloud.
✔ Room-by-Room Control with Wiser Thermostats & TRVs
The CCTFR6311G2D is the hub and boiler interface — but room-by-room control is unlocked by adding Wiser Room Thermostats and Wiser Radiator Thermostats (Smart TRVs) (sold separately). Each room thermostat or TRV can have its own independent daily and weekly schedule and target temperature, allowing different rooms to be heated to different temperatures at different times. The hub coordinates all these demand signals, calling for heat from the boiler only when one or more zones need it. This is the architecture that enables genuine per-room energy saving rather than whole-house scheduling.
✔ Heat Pump Compatible — On/Off Demand Interface
In addition to combi boilers, the 1-Channel HubR can interface with heat pumps via a standard on/off demand signal — the relay output provides a potential-free contact that triggers the heat pump when heating is demanded by the Wiser system. This makes it a viable controller for properties that have converted from a gas combi to an air source heat pump for a single heating circuit. OpenTherm modulation is not available on most heat pumps (which have their own flow temperature management via weather compensation), but the relay interface provides the core demand signal the heat pump needs.
✔ Eco, Comfort & Away Modes — Wiser Home App
Three system-wide modes are accessible instantly from the Wiser Home app or the push button on the hub face: Comfort (normal scheduled operation), Eco (lowers all zone setpoints by a configurable offset — useful when the house is lightly occupied), and Away (switches all zones to a frost-protect setpoint when the property is empty). Away mode can be triggered automatically by GPS geofencing when the last household member leaves, and cancelled when anyone returns. The hub also supports Boost — overriding the schedule for a set period to heat a zone to comfort temperature without permanently changing the schedule.
✔ Boiler Plus Compliant — Smart Home Integration
The Wiser 2nd Generation HubR meets the requirements of Boiler Plus (England) — the 2018 regulation requiring smart controls with automation, optimisation, and time and temperature control when installing a new gas boiler. The hub's OpenTherm interface satisfies the load compensation requirement. It also integrates with the broader Wiser smart home ecosystem: window/door sensors, water leak detectors, motion sensors, and plug-in smart sockets all connect via ZigBee to the same hub. Heating and smart home management happen in a single app, and automation rules can link heating events to smart home triggers — such as lowering the heating setpoint when a window sensor detects an open window.

Frequently Asked Questions
Does my boiler support OpenTherm, and how do I check?
OpenTherm support must be built into the boiler's control board — it is not a software setting added later. Most modern condensing boilers from 2010 onwards support OpenTherm, including current models from Worcester Bosch (Greenstar range), Baxi, Ideal, Vaillant, and Viessmann. To check: look for "OT" terminals on the boiler's PCB terminal strip, consult the boiler's installation manual (it will state whether OpenTherm is supported), or search "[your boiler model] OpenTherm compatible". If your boiler does not support OpenTherm, the Wiser hub automatically falls back to standard relay (on/off) switching — which still provides full smart control, scheduling, app access, and room-by-room control, just without the modulation benefits. You do not need an OpenTherm boiler for the hub to work.
What do I need in addition to the hub to get started?
The hub alone cannot control the heating — you need at least one Wiser Room Thermostat or a Wiser Temperature/Humidity Sensor to provide a room temperature reference for the hub to respond to. The room thermostat pairs wirelessly via ZigBee and requires no additional wiring between it and the hub. You will also need a 2.4GHz Wi-Fi router for app and cloud access. For room-by-room control, add Wiser Radiator Thermostats (Smart TRVs) to individual radiators — each provides independent scheduling and setpoint control for its room, all managed from the same app. None of the Wiser room accessories require their own hub; they all connect to this single 1-Channel HubR.
Does the system work if my Wi-Fi or internet goes down?
Yes — the ZigBee mesh network between the hub and all Wiser thermostats and TRVs operates independently of Wi-Fi and internet. If your broadband or router goes down, the heating continues to run to its last programmed schedule, all room thermostats and TRVs continue to control their zones, and the hub continues to switch the boiler. What you lose during a Wi-Fi outage is remote app access (you cannot change settings from outside the home) and smart speaker voice control. The heating system itself is not dependent on internet connectivity for day-to-day operation.
What is Boiler Plus, and does this hub satisfy the requirement?
Boiler Plus is a UK government regulation (England, in force since April 2018) that requires additional energy-saving features to be installed with every new gas boiler. For combi boilers, at least one of four measures must be fitted: flue gas heat recovery, weather compensation, load compensation, or smart controls with automation. The Wiser 1-Channel HubR satisfies the load compensation and smart controls requirements through its OpenTherm interface (which is a form of load compensation — matching boiler output to actual heat demand) and its time, temperature, and automation capabilities. Installers must record the Boiler Plus measures on the Benchmark commissioning checklist and Gas Safe notification.
Can I add Wiser Smart Home devices like sensors and sockets to this hub?
Yes — all Wiser Smart Home 2nd Generation devices connect to the same hub: window and door sensors, motion sensors, water leak detectors, smoke alarms, and smart plug sockets. These are managed alongside the heating in the Wiser Home app. Importantly, you can create automation rules linking smart home and heating events — for example, automatically lowering a room's heating setpoint when its window sensor detects the window is open, or triggering a boost when the motion sensor detects activity in a room outside scheduled hours. The ZigBee mesh benefits from the additional smart home devices as each one also acts as a mesh relay, extending network range.
Can I use this to control a heat pump rather than a gas boiler?
Yes — the 1-Channel HubR provides an on/off relay output compatible with heat pump demand signalling. When Wiser calls for heat, the relay closes and provides the demand signal to the heat pump's heat call input. This gives you full app-based scheduling, room thermostat control, and remote access for heat pump systems. However, OpenTherm modulation is not used with heat pumps — heat pumps manage their own flow temperature via internal weather compensation or controls; the Wiser hub simply tells the heat pump when to run and when to stop. Check your heat pump's installation manual for the correct terminal connection for an on/off demand signal before installation.

Heating and smart home management happen in a single app, and automation rules can link heating events to smart home triggers — such as lowering the heating setpoint when a window sensor detects an open window.

ℹ Choosing the Right Wiser HubR — 1, 2, or 3 Channel?
1-Channel (CCTFR6311G2D — this product): 1 × Heating. For combi boilers where hot water is on-demand. No cylinder control needed.
2-Channel (CCTFR6312G2D): 1 × Heating + 1 × Hot Water. For conventional or system boilers with a separate hot water cylinder — S-plan or Y-plan systems.
3-Channel (CCTFR6313G2D): 2 × Heating + 1 × Hot Water. For larger properties with two separate heating circuits (e.g., ground floor and first floor zones) plus hot water.

Frequently Asked Questions
Does my boiler support OpenTherm, and how do I check?
OpenTherm support must be built into the boiler's control board — it is not a software setting added later. Most modern condensing boilers from 2010 onwards support OpenTherm, including current models from Worcester Bosch (Greenstar range), Baxi, Ideal, Vaillant, and Viessmann. To check: look for "OT" terminals on the boiler's PCB terminal strip, consult the boiler's installation manual (it will state whether OpenTherm is supported), or search "[your boiler model] OpenTherm compatible". If your boiler does not support OpenTherm, the Wiser hub automatically falls back to standard relay (on/off) switching — which still provides full smart control, scheduling, app access, and room-by-room control, just without the modulation benefits. You do not need an OpenTherm boiler for the hub to work.
What do I need in addition to the hub to get started?
The hub alone cannot control the heating — you need at least one Wiser Room Thermostat or a Wiser Temperature/Humidity Sensor to provide a room temperature reference for the hub to respond to. The room thermostat pairs wirelessly via ZigBee and requires no additional wiring between it and the hub. You will also need a 2.4GHz Wi-Fi router for app and cloud access. For room-by-room control, add Wiser Radiator Thermostats (Smart TRVs) to individual radiators — each provides independent scheduling and setpoint control for its room, all managed from the same app. None of the Wiser room accessories require their own hub; they all connect to this single 1-Channel HubR.
Does the system work if my Wi-Fi or internet goes down?
Yes — the ZigBee mesh network between the hub and all Wiser thermostats and TRVs operates independently of Wi-Fi and internet. If your broadband or router goes down, the heating continues to run to its last programmed schedule, all room thermostats and TRVs continue to control their zones, and the hub continues to switch the boiler. What you lose during a Wi-Fi outage is remote app access (you cannot change settings from outside the home) and smart speaker voice control. The heating system itself is not dependent on internet connectivity for day-to-day operation.
What is Boiler Plus, and does this hub satisfy the requirement?
Boiler Plus is a UK government regulation (England, in force since April 2018) that requires additional energy-saving features to be installed with every new gas boiler. For combi boilers, at least one of four measures must be fitted: flue gas heat recovery, weather compensation, load compensation, or smart controls with automation. The Wiser 1-Channel HubR satisfies the load compensation and smart controls requirements through its OpenTherm interface (which is a form of load compensation — matching boiler output to actual heat demand) and its time, temperature, and automation capabilities. Installers must record the Boiler Plus measures on the Benchmark commissioning checklist and Gas Safe notification.
Can I add Wiser Smart Home devices like sensors and sockets to this hub?
Yes — all Wiser Smart Home 2nd Generation devices connect to the same hub: window and door sensors, motion sensors, water leak detectors, smoke alarms, and smart plug sockets. These are managed alongside the heating in the Wiser Home app. Importantly, you can create automation rules linking smart home and heating events — for example, automatically lowering a room's heating setpoint when its window sensor detects the window is open, or triggering a boost when the motion sensor detects activity in a room outside scheduled hours. The ZigBee mesh benefits from the additional smart home devices as each one also acts as a mesh relay, extending network range.
Can I use this to control a heat pump rather than a gas boiler?
Yes — the 1-Channel HubR provides an on/off relay output compatible with heat pump demand signalling. When Wiser calls for heat, the relay closes and provides the demand signal to the heat pump's heat call input. This gives you full app-based scheduling, room thermostat control, and remote access for heat pump systems. However, OpenTherm modulation is not used with heat pumps — heat pumps manage their own flow temperature via internal weather compensation or controls; the Wiser hub simply tells the heat pump when to run and when to stop. Check your heat pump's installation manual for the correct terminal connection for an on/off demand signal before installation.
