EQUIPMENT TYPE:
This field specifies the operation in which this subbase is
used. When the thermostat model is selected as T7350A,
1H1C; or T7350B, 2H2C; or T7350D, 3H3C, RH; or T7350H,
3H3C, Com; the equipment type can be selected as Standard
or Heat Pump.
When the model is selected as T7350M, Mod; or T7350H,
Mod, Com the equipment type is changed to Standard and
this option is disabled for selection. When the T7350M, Mod,
or T7350H, Mod, Com model type is selected, the Heat Action
and Cool Action options are enabled for selection. The
modulating subbase does not allow for heat pumps.
