INSTALLATION

SAFETY INSTRUCTIONS
Electrical equipment must only be installed and assembled by expert personnel. Before connecting the programmable thermostat, ensure that all associated utilities (pumps, valves, boiler etc.) are not connected to the supply and that the load is within the ratings marked on the thermostat.
LOCATION Install the programmable thermostat approximately 1.5 m above the floor, and away from sources of heat (radiators, sunlight, cookers) and from doors and windows.
CLEANING Clean with a damp cloth only.
IMPORTANT Do not overtighten the screws when installing, as this may warp the base and compromise the functions of the touch screen.
