This thermostat can be used to turn a radiator ON/OFF only if the radiator uses an AC 220V motorized valve (ON/OFF type).
✅ Works if:
-
The radiator is controlled by a 220V AC electric valve
-
The valve only needs open / close control (no modulation)
-
Total load is under 200W
In this case, connect:
-
LIVE → Power input
-
N → Neutral
-
ON / OFF → Radiator valve open/close
❌ Does NOT work if:
-
The radiator uses a manual valve
-
The radiator uses a low-voltage (24V or battery) valve
-
The radiator uses a thermostatic radiator valve (TRV)
-
Proportional or modulating valves are required
