Figure 30.13 A wiring NOTE: Many thermostatmanufacturersidentify the power terminals for the heating and cooling circuits as RH and RC.In operation, when the thermostat closes its contacts, current flows through the holding coil of the relay or contactor, creating a magnetic field. If only one power supply is used, a jumper wire is placed between the RC and RH terminals.Figure 30.13 A wiring diagram of a lowvoltage thermostat. Some
