programme by means of the blue 'select' buttons under the front
flap.
The options include;
AUTO- Timeswitch output follows all programmed ‘ON’ and ‘OFF’ times.
ALL DAY - Timeswitch output operates from 1st ‘ON’ time until
3rd ’OFF’, ignoring all switching times in between.
ON - Timeswitch output will be constantly ‘ON’.

the ability to turn off heating during summer without
