I need a Thermostat recommendation. Here is the situation:
For IAQ reasons, I want to set my heating system to run the fan on high or a normal setting when it is heating and when it is not heating, to run the fan only on low speed (system has a filter and fresh air, see below).
I've looked at the Honeywell Vision Pro series and the White Rogers 1F95-1277 Series 90 Blue.
It seems clear how I run the fan continuously (set fan to on) but it's not clear how I set it up to step the fan down to the low speed when the heat in not on and it's in fan only mode.
If anyone can recommend a thermostat that would do this, I'd greatly appreciate it! System details follow.
-- Entire HVAC system is new, inc the ductwork (its a gut renovation of a very old home)
-- I have a Rudd single stage gas heater, no air.
-- There is a IQair Perfect 16 whole house filter
-- The system brings in ~20% external air.
-- There is no heat exchanger or other equipment
-- I live in San Francisco, so the climate is mild
Note: I cross posted this in the IAQ forum, I hope that was ok!!
