Drayton Wiser Smart Room Thermostat – Wireless Additional Zone Thermostat, White
Drayton Wiser | MPN: WN704R0S0902 | Colour: White
The Drayton Wiser Room Thermostat (WN704R0S0902) is a wireless, battery-operated smart thermostat designed to add room-level temperature control to any Wiser multi-zone heating system. It acts as both a temperature and humidity sensor for its assigned zone, and provides a convenient local display and manual override point in rooms where radiator thermostats are installed. Compatible with every Wiser kit, it connects to the Wiser Hub via Zigbee and is controlled through the Wiser Home app on iOS or Android. It also works with Amazon Alexa and Google Assistant for voice control.
As an additional thermostat, it is the essential companion device when using the Wiser Electrical Heat Switch or Wiser Underfloor Heating Controller, as those devices require a room thermostat to function as the zone controller. For rooms with multiple smart radiator thermostats, the room thermostat provides a central sensing point, cleaner readings away from hot radiator surfaces, and a more accessible control for occupants.
Key Features
Wireless & Battery-Operated
No wiring is required. The thermostat runs on two AA batteries (included) and communicates with the Wiser Hub using the Zigbee protocol. It can be wall-mounted using the supplied bracket or freestanding on any surface using the included table stand, giving complete flexibility over placement.
2.4-inch Full-Colour LCD Touchscreen
The large multi-colour LCD screen displays the current room temperature and the active set-point at a glance. Capacitive touch buttons allow the set temperature to be raised or lowered directly on the device, and a boost function can be activated from the thermostat itself, enabling a temporary temperature increase of 30 minutes to 3 hours without needing to open the app.
Temperature & Humidity Sensing
An integrated humidity sensor gives the room thermostat dual functionality, monitoring both temperature and relative humidity in the room. This data is visible within the Wiser Home app and contributes to accurate zone control.
Zone Controller for Radiator Thermostats
When Wiser Smart Radiator Thermostats are installed in the same room, the room thermostat acts as the zone master. Multiple radiator thermostats can be assigned to it, and the room thermostat's air temperature reading is used to make heating decisions, rather than the radiator surface temperature – improving accuracy and comfort.
Required for Wiser Electrical Heat Switch & Underfloor Heating Controller
The room thermostat is a prerequisite for the Wiser Electrical Heat Switch and Wiser Underfloor Heating Controller. These devices do not operate as standalone zone controllers; they rely on a paired room thermostat to provide the temperature sensing and scheduling for the zone.
Smart App Control – Wiser Home App
Full scheduling, zone management and smart modes are configured and managed from the Wiser Home app, available for iOS and Android. The app supports 7-day, per-room scheduling with independent time and temperature profiles for each zone. It also allows remote control from anywhere with an internet connection, and local access even without internet when connected to the same Wi-Fi network.
Smart Heating Modes
When used as part of a full Wiser system, the room thermostat participates in the system's intelligent modes:
Comfort Mode – learns how long each room takes to reach temperature and starts heating early enough to meet the set temperature at the scheduled time.
Eco Mode – combines Comfort Mode's pre-heating intelligence with optimum-stop logic and weather compensation, turning off the boiler earlier to capitalise on residual heat in the home.
Away Mode – overrides all schedules with a reduced set-point across every zone when the household is away, preventing unnecessary heating while maintaining frost protection.
Open Window Detection – detects a rapid temperature drop consistent with an open window or door and automatically switches off heating in that room to prevent energy waste. Can be enabled or disabled per room in the app.
Voice Control & Smart Home Integration
Compatible with Amazon Alexa and Google Assistant for hands-free temperature adjustment and schedule management. Also integrates with IFTTT, enabling geofencing automations and linking with third-party smart home devices and services.
Anti-Frost Protection
A built-in anti-frost function ensures a minimum temperature floor is maintained, preventing damage to plumbing in rarely used rooms during cold spells.
Flexible Placement – Wall Mount or Desk Stand
The thermostat ships with both a wall bracket and a table stand, so it can be positioned wherever it best reflects the ambient temperature of the room – away from radiators, doorways or direct sunlight – for the most accurate readings.

Compatibility
The WN704R0S0902 is compatible with all current Wiser kits and requires a Wiser Hub (HeatHubR) to operate. It is an essential component when using the Wiser Electrical Heat Switch or Wiser Underfloor Heating Controller. It can be used alongside Wiser Smart Radiator Thermostats to create a complete multi-zone heating solution supporting up to 16 independent zones.
A Wiser starter kit is required before adding this additional thermostat. Compatible starter kits include Wiser Kit 1, Kit 2 and Kit 3.
Frequently Asked Questions
Do I need a Wiser starter kit before buying this thermostat?
Yes. The WN704R0S0902 is an additional thermostat designed to expand an existing Wiser system. It requires a Wiser Hub (included in all Wiser starter kits) to pair and operate. It cannot function as a standalone device.
Does this thermostat control the boiler directly?
No. The room thermostat communicates to the Wiser Hub, which in turn controls the boiler via the HeatHubR relay. For rooms with smart radiator thermostats, the room thermostat acts as zone master – if the room thermostat calls for heat, the boiler fires and the radiator thermostats in that zone open.
Is a room thermostat required for underfloor heating control?
Yes. The Wiser Electrical Heat Switch and Wiser Underfloor Heating Controller both require a paired room thermostat to operate as zone controllers. The room thermostat provides the temperature sensing and scheduling for those zones.
Where should the thermostat be positioned for the best performance?
Schneider Electric recommends mounting it on an interior wall approximately 1.2 metres above floor level, away from direct sunlight, draughts and other sources of heat such as radiators or appliances. This ensures the temperature reading accurately reflects the ambient comfort level in the room.
How long do the batteries last?
Drayton states a battery life of approximately one year under typical usage. Actual life will vary depending on how frequently the thermostat is used locally to boost or adjust temperature.
Can I control the thermostat if the internet is down?
Yes. The Wiser system supports local app access over Wi-Fi even when internet connectivity is unavailable, allowing you to adjust temperatures and view status from within the home. Scheduled heating will also continue to run from the Hub without an active internet connection.
Is the anthracite version any different technically?
No. The anthracite version (WN704R0S0901) is identical in specification and functionality; only the colour of the housing differs.
