MULTI-STAGE TERMINAL OUTPUTS

Refer to equipment manufacturers’ instructions for specific system wiring information.

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 trans- former 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 thermo- stat properly for your multi-stage system. After wiring, see CON- FIGURATION section for proper thermostat configuration.
