|
|
| I have a gas central heating system with a Honeywell ST699 heating/hot water control unit/programmer. For the past two days, I have been unable to get heating but I am still getting hot water. All radiators are on. The pilot light is still on but the boiler and honeywell unit do not kick in and make a noise like they usually do. Does anybody have any suggestions? Could it be the boiler or the honeywell unit? Sorry if this sounds a bit stupid but I am a complete novice when it comes to heating systems. |
