24 Volt Thermostat Wiring - Non-Communicating Thermostat
Connections
NOTE: Wire routing must not interfere with the circulator blower
operation or routine maintenance.
The air handler's integrated control module provides terminals
for "Y1" and "Y2" and "W1" and "W2" thermostat connections.
This allows the air handler to support the systems shown in
the following table. Refer to the following figures for typical
connections to the integrated control module. Thermostat wiring
entrance holes are located in the top of the blower. Wire routing
must not interfere with circulator blower operation or routine
maintenance.
NOTE: A removable plug connector is provided with the control
to make thermostat wire connections. This plug may be removed,
wire connections made to the plug, and replaced. It is strongly
recommended that you do not connect multiple wires into a single
terminal. Wire nuts are recommended to ensure one wire is
used for each terminal. Failure to do so may result in intermittent
operation.

The optional usage of a dehumidistat allows the air handler's
circulator blower to operate at a slightly lower speed during
a combined thermostat call for cooling and dehumidistat call
for dehumidification. This lower blower speed enhances
dehumidification of the conditioned air as it passes through the
AC coil. For proper function, a dehumidistat applied to this air
handler must operate on 24 VAC and utilize a switch which opens
on humidity rise.
