o 2
nd
or 3
rd
stage Auxiliary heating (heat strips)
Do NOT use for line voltage controls (120/240VAC)
Stop! Before removing your existing thermostat do the following:
1. Take a picture of the original wires and terminal connections
2. Label the wires with the terminal markings on the old thermostat
3. Record old thermostat terminals and the wire color connected to them below
