I would like to have full control over the HVAC in our building, such that it can be turned on just an hour before we arrive and turn off at a set time in the evening.
An acquaintance who is an HVAC guy says that these programmable 'stats are available only for AC, not for heating.
This doesn't sound right. Why would it matter what a timer is controlling? The thermostat part of it (heat or cool), yes, but the timer part shouldn't matter, should it?
How can I get a timer for all functions of the thermostat?
Makes? Models? URLs?
Thanks,
