DIMENSIONS EN0R8402 R4 1998 2 T6370/T637 T6370/T6371 FAN -COIL THERMOSTATS FAN ONLY CONTROL1 INSTALLATION Location The XE70 Series thermostat is the temperature control element in the fan-coil or air-conditioning system, and must be located in a position with good air circulation, on an inside wall about 1. 5 m above the floor to sense the average temperature. Do not position the thermostat in draughts, near hot or cold air sources or where it will be affected by radiant heat from the sun or other appliances. Mounting the thermostat Any XE70 Series thermostat can be directly mounted on the wall or on a conduit box (see diagram). Mounting screws are supplied for both alternatives. Wiring the thermostat The standard wiring access is via a hole in the base of the thermostat, near the top edge. The installer must be a trained service engineer OPERATION Sensing element The thermostat sensing element comprises two circular, flexible metal plates welded together at the rims and encapsulating a gas/liquid combination whose pressure changes in response to variations in temperature. This dualdiaphragm expands and contracts with ambient temperature changes to operate a snap-acting switch which controls the heating or cooling circuit. 2. [. . . ] There is only a single output connection capable of powering a fan or a single zone valve in a 2-pipe fan-coil unit. Heat anticipator It is recommended that the heat anticipator is always connected for both heating and cooling operation.
