CHECKOUT After installing a thermostat, make an initial check of the switching action. Verify the switch action by listening to and watching the switch contacts, using a voltmeter between the proper sides of the switch, or by observing the controlled device. 1. Run the setpoint dial to a temperature above ambient. This should cause the thermostat to switch, calling for heat. 2. Turn the setpoint dial setting down gradually. The switch should break contact.
