Terminal
Function
W1
Energizes on call for heating.
Y1
Energizes on call for cooling.
G
Energizes fan on call for heating or cooling or by pressing the
Fan
button.
R
Provides independent switching voltage.
24V
Provides 24 VAC from equipment transformer.
24V(c)
Provides 24 VAC (common) from equipment transformer.
CLK1, CLK2
Connects remote clock/timer for alternate setpoints.
RS2, RS1, RS+V
Connects outdoor air temperature or indoor remote sensors; refer to instructions included
with sensors.

If the transformer (T2) is to power all of the loads, the yellow
pin jumper must be inserted (factory position), which connects
R to 24 V. The jumper is located on the electronics board above
the relays. If a separate 24 V transformer (T1) is to be used,
it must be connected between R and 24 V(c), and the jumper
should not be connected between R and 24 V.
