The transformer is designed to give a certain voltage at a certain current. HVAC, Transformers Siemens 24V Transformer With Housing SEM62.2. The most common application for a 24 VAC transformer is to activate a doorbell chime. For use in thermostats, valve actuators, and dampers.

You have two thermostats, so you're not really using the Rc-Rh as designed. Includes screw terminal connections.

Ichecked the gas valve manual there's no range in its specifications. If a thermostat is thought to have a problem then it can be bypassed with a jumper wire.

A 24-volt transformer is typically used as a control device to turn a higher voltage, generally 120 VAC, into a lower working voltage for switches or relays, such as in a furnace thermostat transformer.

4.1 out of 5 stars 61. Showing all 2 results.

The furnace transformer red wire goes to Rh, and the cooling (A/C) transformer red wire goes to Rc. Do I have one or two 24V transformers in HVAC control circuit. A 40 VA transformer is rated for 40 VA or Volt-Amps on the secondary. The lower voltage is sent to the push button to engage the chime mechanism. HVAC, Transformers Siemens 24V Transformer With Housing SEM62.2. The transformer steps down 120 volts to the 24 volts the thermostat needs, and sends out the 24 volts on two wires. Primary power supply 240V AC, Secondary Power Supply 24V AC.
