Notes Mounting, installation and commissioning The room thermostat should located where the air temperature can be sensed as accurately as possible, without getting adversely affected by direct solar radiation or other heat or refrigeration sources. Mounting height is about 1.5 m above the floor. The unit can be fitted to most commercially available recessed conduit boxes or directly on the wall. Only authorised personnel may open the unit to perform service (Caution: AC 250 V).
