[7] In Installer Setup, set changeover valve to O
or B.
[8] In Installer Setup, set system type to 2Heat/
1Cool Heat Pump.
[9] In Installer Setup, set system type to 2Heat/
2Cool Heat Pump.
[10] In Installer Setup, set system type to 3Heat/
2Cool Heat Pump.
[11] 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.
[12] Install field jumper between Aux and E if
there is no emergency heat relay.
