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.
Comfort Window provides a setting to control
the change-over control signal (B/O) used in
Heat Pump systems. In certain heat pump
systems, the B/O signal energizes during
cooling while other systems expect that the
B/O signal will energize during heating.
Comfort Window is compatible with either type
of system. Simply navigate through the
settings icon to the Equipment Controls
settings page. Select the appropriate option in
each of the selections available.

*Caution!
Please note that it is very important to set up
your system properly – especially if you have an Electric
your system properly – especially if you have an Electric
Heater or if your Gas Heater does not drive the system fan
automatically. If Comfort Window is not set up to drive the
system fan and your system is of this type, it is possible that
your heater will overheat because no air is moving through it.
