Wiring guide
See detailed wiring guides for specific system types on following pages.
Conventional Terminal Letters:
C Common wire from secondary side of
cooling transformer.
Rc Cooling power. Connect to secondary
side of cooling system transformer.
RHeating power. Connect to seconary
side of heating system transformer.
WHeat relay (stage 1).
W2 Heat relay (stage 2).
YCompressor contactor (stage 1).
Y2 Compressor contactor (stage 2).
GFan relay.
K THP9054 connection (see note below)
U1/U1 Configuarable IAQ relay for humidi-
fier, dehumidifier, or vent
U2/U2 Configuarable IAQ relay for humidi-
fier, dehumidifier, or vent
Heat Pump Terminal Letters:
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-
fier, dehumidifier, or vent
U2/U2 Configuarable IAQ relay for humidi-
fier, dehumidifier, or vent
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.”
