Question about Honeywell Focus 6300B 5-2 Days Programmable Thermostat Heater
I just bought a house and replaced an old, non-programmable thermostat with a Honeywell RTH2310 5-2 day programmable. For about 2 months, everything worked perfectly (thru, say, October & November). In December and now in January, something isn't right with the system. FYI: The house has an older ducted forced hot air system. Even if I set the thermostat to a steady temp (and forego the program bit altogether) the system can't maintain that setting. For instance, heat set to 62 this past night, woke up and it's 57 in the house. Went on vacation last week and turned the heat to 60, came back, set it to 68 and it took nearly 5 hours for the heat to even come on. The heat works, and occasionaly the thermostat seems to maintain a temperature, but only after a LONG lag time. It also seems to maintain temperature, just not at what I have the themostat set to...say, maintain about 60 if I have it set at 68.
I have no idea what's going on. I think it might be an electrical issue with lack of communication between thermostat / heating system. The thermostat typically says that it's heating (noted by a fire icon for this model) even if it's not. There is also no 'on-demand' way to make the system work, ie: if I manually turn the heat up, the heat doesn't kick in. Please help.
It sounds like you may have issues with the furnace. A qualified professional can go over the system and the house to let you know if the system and unit are properly sized. The poor performance of a furnace can be a sign of carbon buildup in the furnace.
Good luck, hope this helps.
