You can configure the thermostat for use with either multi-stage electric heat systems or multi-stage gas systems. When configured for electric heat, the G terminal (blower/fan) will be energized on a call for heat. This thermostat is designed to operate a single-transformer system. If you have a two- transformer system, cut and tape off one transformer. If transformer safety circuits are in only one of the systems, remove the transformer of the system with NO safety circuits. If required, replace remaining transformer with a 75VA Class II transformer. After disconnecting one transformer, the two commons must be jumpered together. Use the terminal output information below to help you wire the thermostat properly for your multi-stage system. After wiring, see CONFIGURATION section for proper thermostat configuration.

E2/P SWITCH The E2/P switch is located on the back of the thermostat body (see fig. 2). This switch controls how the E2/P terminal of the thermostat will be energized. When the switch is in the E2 position (down), the E2/P terminal will be energized only when in emergency heat. When the switch is in the P position (up), the E2/P terminal will always be energized except when in emergency heat. Consult the equipment manufacturer or a qualified heating/cooling service person before setting this s...
