Ok. I've got a York Affinity series heat pump (2 stage) with a York NG
furnace as a backup. Here's the question:

Should it , or should it not 'automatically' go on to the gas furnace when
the heat pump is not satisfying the thermostat? I'm in a house that's not
insulated, (soon to be, problem will probably go away) and with the
thermostat on 76 and the outside temp at about 40, it was not able to bring
the room above 72. I kept thinking it should kick in the furnace. I have a
call in to my installer, and he was going to investigate it a bit. He was
on a ladder at the time and not sure of the answer. I'm thinking this would
almost have to be a function of the thermostat, as the heat pump logic would
not know the room temperature. OR does it? The thermostat is the WR
comfort set 90 model 1F95-377 . thanks for any input..

It depends on the board in the furnace (if it has dipswitches or
jumpers.
It depends on the thermostat used.
It depends on the way the thermostat was set up.
It depends on how the installer wired it.
The best way to control it is with the Honeywell IAQ stat
(YTH9421C1010) but it aint a cheap stat.

Don't be a cheapskate. Get the better stat.

By the way, how about not getting your panties in a wad until the house is
finished, OK?
