Just had a new gas pack installed and the thermostat put in is a Honeywell
T8600D 2069 Chronotherm !V Plus programmable thermostat
The system works good and am happy with it, However, when the times are set
for return and wake, The furnace comes on at least 1 1/4 hours
before the time set. So it ends up the house is heated way longer than
wanted. Is this normal or do I possibly have a thermostat that is
defective or needs some adjustment? System replaced a gas pack installed in
'89 and also had a programmable thermostat with it. It work without any
problems and usually fired up the furnace very close to the time set.
Thanks for any information in advance.
