NOTES
Wire specifications:
Use 18- to 22-gauge thermostat wire.
Shielded cable is not required.
[6] Use a small piece of wire (not supplied) to
connect W and Y terminals.
[1] Power supply. Provide disconnect means
and overload protection as required.
[2] Remove jumper for 2-transformer systems.
[3] Optional 24 Vac common connection.
[4] Common connection must come from cool-
ing transformer.
[7] Set fan operation switch to Heat Pump (see
page 5) and configure system type for heat
pump (see page 6).
[8] L terminal sends a continuous output when
thermostat is set to Em. Heat. Connect
to Honeywell zoning panels to switch the
panel to Emergency Heat.
[5] Use either O or B terminals for changeover
valve.
[9] Install field jumper between Aux and E if
there is no emergency heat relay.
