In Installer Setup, set changeover valve to
O or B.
In Installer Setup, set system type to
2Heat/1Cool Heat Pump.
In Installer Setup, set system type to
2Heat/2Cool Heat Pump.
In Installer Setup, set system type to
3Heat/2Cool Heat Pump.
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.
Install field jumper between Aux and E if
there is no emergency heat relay.
