Equipment Controls
Comfort Window supports different settings
relating to Gas and Electric heaters, along with
settings for different actions for Heat Pump
change-over (B/O signal).
Gas heaters typically drive the system fan
during heating time periods, while Electric
Heaters or Heat Pumps typically expect the
thermostat to control the system fan during
heating. Comfort Window provides an option
to stop driving the system fan during heating
time periods to allow the Gas Heater to drive
the fan*. Alternatively, Comfort Window can
also be set up to drive the system fan during
heating time periods for Electric Heaters.
