WIRING CONNECTIONS

* The RC/PS switch shown in Figure 1 configures the thermostat for Hardwire or Power Stealing.

The factory setting is RC (Hardwire) and requires a Common connection from the system transformer to the "C" terminal on

the thermostat. If no common wire is available for the thermostat "C" terminal, move the RC/PS switch to PS (Power Steal-

ing). NOTE: If set to PS (Power Stealing), the thermostat "C" terminal must not have a wire connected.
