To wire the thermostat for AC power, Connect common Jumper side of transformer connect the common side of the cool- to “C” terminal ing transformer to the “C”terminal as shown at left. Important: Remove R/Rc jumper for 2-transformer systems only. (See wiring diagram on page 5.) Battery Power The thermostat can be powered by batteries alone or, if used with AC power, can provide backup power to the display during power interruptions. After installation, batteries can be changed without removing the ther- mostat from the wall (see page 15). Install batteries in back of thermostat (optional if AC powered). To Mount Thermostat 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. 10 FocusPRO™ TH5220D Non-programmable Digital Thermostat Installer setup Follow the procedure below to configure the thermostat to match the installed heating/cooling system, and customize feature operation as desired.

To prevent equipment damage, avoid cycling the compressor quickly. 13 Installation Guide Auto changeover (Setup Function 12) Fan System Auto Changeover is a feature used in Auto Auto climates where both air conditioning and heating are used on the same day.When the system is set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 3 degrees apart.The thermostat will automati- cally adjust settings to maintain this 3-degree separation (called “deadband”). The 3-degree separation between heating and cooling set temperatures is fixed, and cannot be changed. Built-in compressor protection (Setup Function 15) Inside Cool This feature helps prevent damage to the ° Setting compressor in your air conditioning or heat ° pump system. 75 Cool On 75 Damage can occur if the compressor is re- started too soon after shutdown.This feature Fan System Auto Cool forces the compressor to wait for a few minutes before restarting. During the wait time, the message Cool On Message flashes until safe or Heat On (heat pumps only) will flash on restart time has elapsed the display.When the safe wait time has elapsed, the message stops flashing and the compressor turns on. Auxiliary heat control (Setup Function 26) Systems with heat pumps can be set to operate in one of two ways: Comfort Setting: The thermostat will prioritize comfort over economy depending on heat pump performance, load conditions and whether the equipment is calling for heat. Raising the temperature just a few degrees will often activate auxiliary heat. Economy Setting: The thermostat will attempt to reach the temperature set- ting without activating auxiliary heat. The thermostat waits a preset time before allowing auxiliary heat to be activated depending on the compressor stage performance, and on how many degrees the temperature setpoint is changed. 14 FocusPRO™ TH5220D Non-programmable Digital Thermostat Quick reference to controls Digital display screen Battery holder (see page 10) Temperature buttons Press to adjust temperature settings Function buttons Press to select the function displayed just above each button.
