I had to replace an old thermostat last year (Taco), so I replaced it

The unit was installed by my heating contractor.

Problem #1. contractor left all settings at factory settings. I
noticed last year that the zone controlled by this thermostat were
cold.

Wow! after installing it, didn't even test it to make sure it is working
OK? What kinda work is that?

Hey! That was an HVAC Professional (TM)! Have some respect! If a Professional

an automobile through an exterior wall, or someone stole all their windows.
