Central Heating will not
switch off
Check that the timer tappets are set to the inner edge of the dial.
Check the room temperature is not below 5ºC (frost protection).
Rotate the room thermostat knob until the set point is 5ºC
Check that the Timer On/Timed/Off switch is off ( or the unit is timed off)
Stand next to the boiler holding the room thermostat for 5 mins. If the
central heating switches off then the room thermostat was either too far
away from the boiler or there were unsuitable materials between the
boiler and the room thermostat. Re-position room thermostat.
Change the batteries in the room thermostat.
Replace both the RF Timer and the RF Room Thermostat for a new pair.
