Radbot 1 Intelligent Thermostatic Radiator Valve SCV100-000 - Self-Learning TRV No App Required

Radbot 1 Intelligent Thermostatic Radiator Valve SCV100-000 - Self-Learning TRV No App Required

The Radbot 1 (SCV100-000) by Secure Meters is a self-learning intelligent thermostatic radiator valve (TRV) that replaces any standard TRV head and automatically adapts to how each room is used — with no app, no Wi-Fi, no schedule-setting, and no engineer required. An on-board occupancy-detection algorithm senses when a room is occupied or empty and adjusts the radiator's heat output accordingly, ensuring you are warm when you are in a room and not wasting energy when you are not. Compatible with combi, system, and heat-only boilers, district heating, and air source heat pumps (flow temperature above 45 °C), the Radbot 1 fits the vast majority of UK radiator valves via five included adaptors and installs in minutes using only 2 AA batteries. A 30-minute comfort boost button, frost protection at 6 °C, automatic humidity-triggered temperature uplift, and a weekly valve maintenance cycle complete the feature set — making Radbot 1 one of the most capable no-fuss smart TRVs available.

⚠ Important Compatibility Notice
Radbot 1 is not compatible with electric heating systems or electric radiators. It is designed for wet central heating systems only. For heat pump systems, Radbot 1 is compatible only where the flow temperature is above 45 °C. Do not install Radbot 1 in the same room as your main room thermostat — this can cause the boiler to run continuously if the thermostat calls for a higher temperature than the radiator valve allows.
⚠ Siting Notice
Do not install Radbot 1 behind curtains, radiator panels, or furniture. The device must have free airflow around it to sense room temperature and detect occupancy accurately. Obstructed units will not learn or control heat correctly.

Key Features
Self-Learning Occupancy AI

At the heart of Radbot 1 is an on-board artificial intelligence algorithm that continuously monitors room conditions and builds a picture of when each room is occupied and when it is empty. Over the first few days of use it learns your household's patterns, then uses that intelligence to pre-heat rooms before you arrive and set back the temperature when you leave — entirely automatically, without any input from you.

No App, No Wi-Fi, No Schedule

Unlike most smart TRVs, Radbot 1 requires no smartphone app, no Wi-Fi connection, no hub, and no programmed schedule. Simply install it, set the comfort dial to your preferred temperature, and the device does everything else. This makes it equally suitable for households that want smart heating without any of the complexity — and continues working perfectly even if your internet goes down.

1–5 Comfort Dial (15 °C to 24 °C)

The five-position rotary dial sets the target comfort temperature on a scale of 1 to 5, with position 3 corresponding to 19 °C. Each full step changes the setpoint by 2 °C; each click within a step changes it by 1 °C. The dial also accesses frost protection (❄ = 6 °C) and maximum heat (position 5 = 24 °C). As the dial is turned towards cooler settings, the maximum energy-saving temperature setback is increased — giving you direct control over how aggressively the algorithm saves energy.

30-Minute Comfort Boost

Press the Boost button to immediately drive the valve to maximum open for 30 minutes, overriding the AI's current setback if the room is empty or cool. At the end of the boost period, Radbot 1 automatically reverts to the previously set temperature — no need to remember to turn it down. If you press Boost by accident, briefly turning the dial down and back cancels it.

Frost & Humidity Protection

With the dial set to the snowflake (❄) position, Radbot 1 enters frost protection mode and maintains a minimum temperature of 6 °C — enough to protect the property and pipework from freezing. Additionally, the device automatically detects high humidity levels and temporarily raises the temperature setpoint to reduce the risk of condensation and damp — useful in bedrooms and bathrooms.

Weekly Valve Maintenance Cycle

Radiator valve pins can seize if left in one position for extended periods — particularly common in summer when heating is not in use. Radbot 1 automatically performs a weekly decalcification cycle, fully opening the valve pin and returning it to its set position. This prevents stuck pins without any manual intervention, reducing the likelihood of a seized valve causing a no-heat fault when the heating season begins.

Tool-Free DIY Installation

Radbot 1 fits over an existing TRV body — no plumbing, no draining down, no tools, and no electrician required. Remove the old TRV head, select the correct adaptor from the five included, click Radbot 1 into place, hand-tighten the retaining ring, and insert the batteries. The whole process typically takes under five minutes per radiator. If your radiators currently have manual valves rather than TRV bodies, a plumber will need to fit TRV bodies first.

Wide System Compatibility

Compatible with combi boilers, system boilers, heat-only boilers, district heating, and air source heat pumps (flow temp >45 °C). The five included adaptors cover the most common UK and European radiator valve thread types: M30 × 1.5, M30 × 1.0, M28 × 1.5, Danfoss RA, and Danfoss RAVL. Not compatible with electric heating or electric radiators.

Frequently Asked Questions
How does the self-learning algorithm work?
Radbot 1's on-board AI monitors room conditions continuously, building a model of when the room is typically occupied and empty throughout the week. Over the first few days it gathers data; over the following week or two it refines that model. Once established, it uses the pattern to pre-warm the room before you usually arrive and set the temperature back when you leave — without you doing anything. If your routine changes, the algorithm adapts over the following days. There is no manual schedule to set, and nothing is transmitted to the internet — all processing happens inside the device.
Will Radbot 1 work with my heat pump?
Radbot 1 is compatible with air source heat pumps provided the flow temperature is above 45 °C. Many modern ASHP systems are designed to run at lower flow temperatures (35–45 °C) for underfloor heating or highly insulated properties — in those cases, Radbot 1's motorised valve may not provide sufficient control authority. If you are unsure of your ASHP's flow temperature, check the system settings or consult your installer before purchasing.
Can I install Radbot 1 myself, or do I need a plumber?
If your radiators already have existing TRV bodies, Radbot 1 can be installed by any competent adult in under five minutes per radiator — no tools, no draining, no plumbing work needed. Simply unscrew the old TRV head, fit the correct adaptor from the five supplied, and secure Radbot 1 by hand. However, if your radiators currently have manual valves rather than TRV bodies, a qualified plumber will need to fit TRV bodies first before Radbot 1 can be installed.
Why can't I install Radbot 1 in the same room as my room thermostat?
Your room thermostat controls the boiler — if it calls for heat, the boiler fires. If Radbot 1 closes the radiator valve in that same room while the thermostat is still calling for heat (because the thermostat's setpoint is higher than Radbot 1's setpoint), the boiler will run continuously without being able to satisfy the thermostat, wasting energy and potentially causing overheating. Install Radbot 1 on radiators in other rooms only — leave the thermostat room's radiator on a standard valve or a conventional TRV.
What does the LED flashing indicate?
The LED uses different flash patterns to communicate status. One long flash on power-on confirms the device is active. During Boost, it gives an immediate long flash then medium flashes every 2 seconds for two minutes, then every 8 seconds for up to 30 minutes. Repeated medium flashes every 2 seconds indicate a low battery warning. Rapid continuous flashing (more than once per second) indicates a hardware or software fault — contact Secure Meters support. A single flash acknowledges a dial position change.
What happens when I change the batteries?
Radbot 1 retains its internal memory of recent occupancy events and heating patterns when batteries are changed, provided the new batteries are inserted within 5 minutes of removing the old ones. Waiting longer than 5 minutes may cause the device to lose its learned schedule, requiring it to re-learn your patterns over a few days. The low battery warning LED (repeated medium flashes every 2 seconds) gives you advance notice so you can plan the battery change.
