N N o o t t e e : : Any incorrect input combinations are captured as thermostat wiring failures and will
light the STATUS LED indicator on main board.
Anytime there is a second-stage call for heating from the wall thermostat,, the unit
automatically switches over to electric heating for heat pump models.
For thermostats with two (2) fan speed output (such as Low fan or Hi fan), the fan speed is
determined by how the terminal connector is wired. When using Low fan speed, wire the GL
output from the thermostat to GL on the terminal block. When using Hi fan speed, wire the
GH output from the thermostat to GH on the terminal block.
