!&"# FEATURES G Controls central heating systems to provide different room temperatures up to 6 times a day. G The TP3 and TP5 have one programme for Monday to Friday, with a different programme for Saturday and Sunday. G TP2 and TP3 have minimum temperature setting of 16°C, ideal for use in elderly persons accommodation. G Setting the TP4 and TP5 to the lowest temperature will effectively switch off the heating, whilst providing frost protection for the controlled area.* G A constant low temperature is easily selected while away from home, for example, when on holiday. G Battery operated. Ideal for low voltage control circuits, e.g. some combi-boilers, as well as for mains voltage circuits. Batteries can be changed without loss of programme. G Wiring conversion chart for common room thermostats included. * This low temperature selection should not be used for Frost Protection if some parts of the heating system are in an exposed location. INSTALLATION INSTRUCTIONS NEW INSTALLATION Choose a fixing position where the thermostat will sense the room temperature without being affected by draughts or heat sources such as radiators, open fires or direct sunlight. Fix at height of approximately 1.5 metres from the floor. Cable entry is from behind if fitted to a single gang flush box, or from above, below or from the left if surface fixed cable is used. Fig.1. shows fixing hole dimensions and the clearance required for the removal of the sliding cover, and for air flow over the sensor. Standard M3.5 screws are used to fix the thermostat to a flush box, or No.6 woodscrews and wall plugs of adequate length should be used for surface fixing. REPLACING AN ORDINARY ROOM THERMOSTAT Switch OFF the power to the central heating system. Carefully note which wire colours are connected to which terminal numbers of the existing thermostat. If the existing thermostat has no indication of the numbers of each of its terminals then a qualified electrician should be called before proceeding any further. Remove the existing thermostats mounting plate from the wall, and prepare the wall to receive the Programmable Room Thermostat. Refer to Fig.1. for dimensions. Connect the wires to the new thermostat referring to the wiring conversion chart overleaf. NOTE: Some existing thermostats will have a Neutral wire and/or an Earth wire connected. These wires must NOT be connected to the new terminals, but made electrically safe and coiled in the recess at the back of the new thermostat. If in any doubt about the function of every wire connected to the existing thermostat, call a qualified electrician for advice. Fig.2.
