Electric or Heat Pump: Change the switch to this setting for heat pump or electric heat systems. (This setting is for systems that allow the thermostat to control the fan in a call for heat, if a fan wire is connected to the G terminal.) Install two AA alkaline batteries in the back of the thermostat, as shown at left. Fresh batteries should be installed immediately when the REPLACE BATT warning begins flashing (see page 10.) The warning flashes about two months before batteries are depleted. Even if the warning does not appear, Batteries should be replaced once a year, or before the home is left vacant for more than a month. Install batteries in back of thermostat Thermostat mounting Set fan operation switch 6 Align the 4 tabs on the wallplate with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps in place. 7 Installation Guide PRO TH3110B Non-programmable Digital Thermostat Fan operation settings Battery installation • • Gas or Oil: For gas or oil heating systems, leave the fan operation switch in this factory-set position (This setting is for systems that control the fan in a call for heat.)
