Safety Instructions
Danger! Risk of electric shock!
WARNING
• Installation must be carried out by a qualied electrician and conformed to current IEE Regulations!
• Mains supply must be suitably fused (usually 3 amps) and provision made for Class A circuit disconnection�
• Control is suitable for xed wiring only�
• If the unit is to be surface wired: – Remove backplate by slackening xing screw and separating plate and timeswitch� – Remove the knock out from the backplate and the timeswitch� – Screw backplate to wall with counter sunk number 8� (Wood screws using xing holes provided�)
• For switch mounting: – Use the centre two holes and x backplate to box using machine screws� – To ensure clearence for the down ap, ensure that there is a minimum of 4 cm clearance under the unit when mounted�
Connection and mounting must be performed by a professional electrician!

What is a programmer?
Programmers allow you to set ’On’ and ’Off’ time periods� Some models switch the central heating and domestic hot water on and off at the same time, while others allow the domestic hot water and heating to come on and go off at different times�
Set the ’On’ and ’Off’ time periods to suit your own lifestyle� On some programmers you must also set whether you want the heating and hot water to run continuously, run under the chosen ’On’ and ’Off’ heating periods, or be permanently off�
The time on the programmer must be correct� Some types have to be adjusted in spring and autumn at the changes between Greenwich Mean Time and British Summer Time�
You may be able to temporarily adjust the heating programme, for example, ’Override’, ’Advance’ or ’Boost’� These are explained in the manufacturer`s instructions�
The heating will not work if the room thermostat has switched the heating off� And, if you have a hot water cylinder, the water heating will not work if the cylinder thermostat detects that the hot water has reached the correct temperature�

• Carry out wiring installation using appropriate diagram as shown�
• When the TOWERCHRON QM1 timeswitch is to be used with a combination boiler, always refer to the boiler manufacturers instructions concerning electrical wiring before using the information contained in this leaet� In some cases the boilers manufacturers instructions will contain information regarding removal of certain link wires and will always indicate the fuse rating for the mains electrical supply�
• Plug in unit and secure to the base by tightening xing screw�
