How To Program T8635l Thermostat 2 Questions
house bought a year ago has a T8635L thermostat and had never had a reason to program it till now...
1) the boiler maint guy took the thermostat off the mounting plate and then put it back on and now the boiler keeps running continuesly at 75 F. instead of prev settings. Why and what can I do to reset it back to original settings.
2) if I want to reprogram the thermostat do I first go into installer setup choose option 25 to unlock the keyboard and then follow the user manual instructions to do the settings for wake, leave, return and night settings?
I am reading both the installer setup and the user manual and I am very confused on how to set the thermostat
thanks
