Shielded cable is not required. [7] In Installer Setup, set changeover valve to O or B. [8] In Installer Setup, set system type to 2Heat/1Cool Heat Pump. [1] Power supply. Provide disconnect means and overload protection as required. [2] Remove jumper for 2-transformer systems. [3] Optional 24VAC common connection. [4] Common connection must come from cooling transformer. [5] In Installer Setup, set system type to Heat Only. [6] In Installer Setup, set system type to 2Heat/2Cool Conventional. 69-1922EFS-01 [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. 4
