Room thermostat needs to placed in the room which is used most
frequently. For instance; living room or lounge. Placing the room
thermostat in a spot that have air circulation like entrance of a room
or side of window should be avoided. Also anywhere close to heating
units such as radiator, stove and spots which get direct sun light

against materials such as liquid, dust etc. You can place your receiver
in boiler’s cabinet without physical contact with boiler or you may
mount receiver to wall.
