SYSTEM CONFIGURATION
Fig. 23 – Wall Thermostat
Control Panel Label
(Part# 62261101)
NOTE: For thermostats that have only one fan speed output (on or auto), the fan speed
is determined by how the terminal connector is wired. If Low fan is desired, wire the
G output from the thermostat to GL on the unit’s terminal block. If Hi fan is desired, wire
the G output from the thermostat to GH on the unit’s terminal block.
