User Instructions Your programmer Your Programmer & Programming the unit The 4033 programmer allows you to switch your hot water and heating on and off at times that suit you. Four tappets on the timing dial let you decide when you want your hot water and heating to come on and go off each day. The programmer provides 2 ON times and 2 OFF times per day. Using two simple switches you can run your Heating and Hot Water independently of each other, either at the set times, constantly ON, constantly OFF.
2 Still holding the central knob, move the blue tappet marked ‘B’ to the time you want your HEATING/HOT WATER to switch off in the morning. 3 You can set your other two tappets in the same way to set your HEATING/HOT WATER for the afternoon or evening. EXAMPLE (NB.
Using the Programmer The 2 switches are used to select how the 4033 controls your hot water and heating. The heating and hot water can be operated independently, in various combinations. TIMED OFF OFF ON ON Using the programmer HEATING 10 TIMED WATER Each of the selector switches can be put into one of three positions marked ‘TIMED’, ‘OFF’ and ‘ON’. They operate completely independently of one another, letting you select different programmes for each service.
o TIMED - the Hot Water will be switched ON and OFF according to the times at which the tappets have been set. o OFF - the Hot Water will ignore the tappet positions and remain OFF. o ON - the Hot Water will be ON constantly. This enables you to switch the Hot Water ON during a period when the time clock is off, enabling you to have constant hot water.
