Standard Terminal Outputs
Refer to equipment manufacturers' instructions for specific system wiring information. You can configure the receiver 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.
Dual Transformer System:
If you have a two-transformer system, cut and tape off one transformer. If the transformer safety circuits are in only one of the
systems, remove the transformer of the system with NO safety circuits. If required, replace the remaining transformer with a
75VA Class II transformer. After disconnecting one transformer, the two commons must be connected 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.
