Installation
Room thermostat
If fitting a new room thermostat for this system;
• Position it out of direct sunlight and draughts
• Position it away from internal heat sources
• Position it in a room without a TRV on the radiator/heat emitter.
• Position it on an internal wall
Note:
Do not position the thermostat excessively close to the ex-
ternal wall.
The thermostat may detect the temperature of the wall, which
could affect appropriate control of the room temperature.
