The Central Heating system is controlled by a Lifestyle LP522 Programmer and a Honeywell Room Thermostat (I believe a T6360B).
The boiler fails to react. I do not suspect a boiler fault as the boiler fires when called for (hot water) from the other half of the LP522 and from a separate programmer for the heated towel rails.
Any suggestion on how I can establish whether the Programmer or Thermostat is at fault would be appreciated.
