How to set a digital timer

Check the clock is showing the correct time. If not, put the timer switch to ‘clock’ and adjust the time using the ‘forward’ and ‘reverse’ buttons. Reset the timer switch to ‘auto’. Set the ‘heating’ and ‘hot water’ switches to come on once, twice, or stay on all the time, as you require. During freezing spells, keep the heating on all the time, and turn the thermostat down during the night and if you are out all day.

How to set a clock timer

Turn the clock until it is showing the correct time. Decide when you want the heating to come on and go off and set the pins or arrows for those times (see below for how to change pins and arrows). Set the timer switch to ‘timer’ or ‘auto’ as appropriate to the unit. During freezing spells, keep the heating on all the time, and turn the thermostat down during the nigh and if you are out all day.

How to control the temperature

To set the thermostat turn the dial so that the arrow or marker is against the temperature setting you want. A comfortable temperature is between 18°C and 22°C.
