CCommon wire from secondary side of
cooling system transformer.
Rc Cooling power. Connect to secondary
side of cooling system transformer.
RHeating power. Connect to secondary
side of heating system transformer.
O/B Changeover valve for heat pumps.
Aux/E Auxiliary/Emergency heat relay.
YCompressor contactor (stage 1).
Y2 Compressor contactor (stage 2).
GFan relay.
LHeat pump reset (powered continuously
when System is set to Em Heat; system
monitor when set to Heat, Cool or Off).
K THP9054 connection (see note below)
U1/U1 Configuarable IAQ relay for humidi-

Note: Use the Kterminal in place of the Yand Gterminals to provide full fan and compressor
control though a single wire. The K terminal must be connected to the THP9045 Wiresaver
module (see page 14). The K terminal can not be used in heat-only applications.
Note: Do not connect wires to terminals marked “Not Used.”
