Installation Pre-Selector wheel Selector switch Plug-in replacement module Installation Wallplate/Terminal block (not with FRU units) NB. For FRU units - go straight to to point 4 on page 5 1. Loosen the fixing screw in the base of the unit to release the grey plastic Wiring Cover. Ensure the protective tape over the thumbwheel remains in place. 2. Holding the unit clockface downwards, press firmly in the centre of the wallplate and slide it from the module as shown.
3. Fix the Wallplate/Terminal Block to the wall with countersunk No.8 woodscrews or to a steel box to BS 4662. 1970 or a surface mounting steel or moulded box having centres of 23/8” (60.3mm). 4. Referring to the Wiring Diagrams on page 6, connect the unit as shown. Ensure that terminals 3 and 6 are linked where required (Mains Voltage applications) with insulated cable capable of carrying full load current. 5.

User Instructions Your programmer Your 102 mini-programmer allows you to switch your heating and hot water on and off at times that suit you. Normally the 102 provides 2 ON periods and 2 OFF periods each day. However 1 ON and 1 OFF period can be obtained by using the Pre-Selector Wheel (see page 11). You can choose whether the 102 controls your hot water & heating together, just the hot water or neither system (OFF) using the manual rocker switch.
Setting the time of day The dial on the front of the 102 displays the hours of the day using the 24hour clock. TIME mark Setting the time & the programme Remove dial cover (turn slightly to the left and pull off) Turn the dial clockwise until the correct time is aligned to the TIME mark (as shown). IMPORTANT: turn the dial clockwise only ! Remember you will have to re-set the time after a power-cut, and also when the clocks change in Spring and Autumn.
Example: If you want your system ON between 8am and 10am and again between 4pm and 11pm, set the tappets as shown. (A to 8, B to 10, C to 16, D to 23). A = 1st ON B = 1st OFF C = 2nd ON Remember: Red tappets (A and C) switch ON Blue tappets (B and D) switch OFF 3. Ensure that the installer has removed the protective tape covering the pre-selector wheel. 4. Using the dial knob, rotate the dial completely at least twice, clockwise only, to clear the mechanism.
Selecting operating mode The Rocker Switch on the side of the unit is used to select how your 102 controls your hot water & heating system. You can manually select either: hot water only hot water & heating together neither (system OFF) Switch positions Selecting operating mode System OFF 10 Hot water only Heating & Hot Water together The 102 unit is now set, and the current status of the mini-programmer can be seen on the wheel at the top righthand corner of the unit, (e.g.
Overriding the programe using the Pre-Selector wheel The pre-selector wheel can be used to override the set programme on occasions when you need to change from your normal heating routine. Example: Your programme is set so that your heating comes on at 4pm but you arrive home earlier than usual, at 2pm and need the heating ON immediately. Turn the wheel anti-clockwise until it displays ON UNTIL `D’ as shown.
