I'm looking for recommendations for programmable thermostats - didn't
really see what I was looking for in the archives.
I've got 2 heat pumps - I downstairs/1 upstairs. Trane X1000s I
I would like a 7 day programmable unit. I would also like to be able to
control the upstairs unit from downstairs, even if it means giving up
the thermostat upstairs. Humidity control would be nice as well, as
would being able to control an Aprilaire humidifier (I doubt something

I'm not sure what to look for as far as number of stages/zones/etc.
Altho, you really dont want the stat controlling your humidifier. Upgrade it
to a 600 series with an induct humidistat, and an outdoor sensor.
The Honeywell Vision Pro line, (NOT the cheap $100 ones at Home Depot) and
Robertshaw offer the options for outdoor sensors, and remote sensors.
You dont need a zone controller, unless you have zone dampners, unlikely
with a heat pump./
Get a Honeywell TH8321U1006 which has humidity control built in.
Get a Honeywell TH8320U1008 for the one that doesn't have the Aprilaire
Do not try to control the upstairs unit from the downstairs.
Thanks for the info.
I guess if I wanted to control both units downstairs, I would need to
put in a remote temp sensor upstairs and run the control wires (from
the old upstairs thermostat location) to the downstairs location?
Yes, but I don't know if you can use the Honeywell models to control both
humidity and temperature from one thermostat. Maybe someone else could
answer that. I love Honeywell thermostats, but have had poor results with
their outdoor sensors. Maybe there's another brand that makes better
