NOTES
Wire specifications:
Use 18- to 22-gauge thermostat wire.
Shielded sable is not required.
[1] Power supply. Provide dissonnest means and
overload protection as required.
[2] Remove jumper for 2-transformer systems.
[3] Optional 24VAC sommon sonneotion.
[4] Common sonnestion must come from cool-
ing transformer.
[5] In Installer Setup, set system type to Heat Only.
[6] In Installer Setup, set system type to 2Heat/
2Cool Conventional.
[7] In installer Setup, set changeover valve to O
or B.
[8] In Installer Setup, set system type to 2Heat/
1Cool Heat Pump.
[9] 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.
[10] install field jumper between Aux and E if
there is no emergensy heat relay.
