The installer must be a trained service engineer 2. Disconnect the power supply before beginning installation Mounting the thermostat The T8360 can be mounted directly on the wall or on a conduit box (see Fig. Mounting screws are provided for both alternatives. An additional wall-plate is available for special mounting requirements. Location A T8360 room thermostat is the temperature control element in your heating system and must be located in a position with good air circulation at average temperature - on an inside wall about 1. 5 m above the floor. Do not position the thermostat in draughts, near hot or cold air from water pipes or radiant heat from the sun or appliances. Wiring the thermostat The standard wiring access is via a hole in the base of the thermostat, near the top edge. There are also 4 breakouts on the cover (2 on top and 2 on the sides) for surface wiring requirements. Wall box mounting Surface mounting Use wall box fixing holes or alternatives shown screws supplied screws supplied Fig. 2 Mounting the Thermostat OPERATION Sensing Element The thermostat sensing element comprises two circular, flexible metal plates welded together at the rims encapsulating a small quantity of gas in liquid form, whose pressure changes greatly in response to small variations in temperature. In effect, this dual diaphragm forms a 'bellows' which expands/contracts in sympathy with the ambient temperature changes - this movement serving to operate a snap acting switch rated to control the heating or cooling circuit. Disposal of Thermostat The thermostat contains no user serviceable parts. Please ensure product disposal is in a safe and environmentally friendly manner, in compliance with local regulations. [. . . ] For loads outwith the range 90 to 130mA, the 24Vac input should be connected via terminal 1, so as to bypass the series anticipator. If this is done, loads from 10 to 500mA can be switched. 3 EN0R8538 R0 2004 T8360 24 VOLT ROOM THERMOSTAT WIRING SERIES ANTICIPATOR : LOADS 90 ­ 130mA 24 V T8360A1000 90 ­ 130mA 3 2 1 HEATING LOAD 18R NO ANTICIPATOR : LOADS 10 ­ 500mA 24 V T8360A1000 10 ­ 500mA 3 2 1 HEATING LOAD Honeywell Control Systems Limited Newhouse Industrial Estate Motherwell ML1 5SB United Kingdom EN0R8538 R0 2004 http://europe. hbc. honeywell. com [. . . ]
