Honeywell Chronotherm Plus Thermostat - Trane XL19i Condenser – I have a Honeywell Chronotherm Plus 8624D running a Trane XL19i with a Trane XV90 - all installed new in new construction in 2003. Every winter, during the morning warm-up from 66 to 70, the burners stays on for approximately 1.5 hours at 70, then rises quickly to 73 before finally shutting off. The only way to interrupt the process is to turn the system to OFF at the thermostat. The system is on AUTO with the cooling set at 75 for the winter. I have swapped the thermostats (there are two sets in the house, this is the one in the attic for the second floor) with the same results. I have not swapped the thermostat circuit boards, but I can not see a reason to. The main floor is on the same schedule, but has never done this three degree burst. I have had three different contractors out, with corresponding charges for thermostat troubleshooting with no luck. Have you ever seen this? Any thoughts? Thanks! (more…)
