Checkout After installing a thermostat, make an initial check of the switch action. Remove the thermostat cover by removing the two (2) thermostat cover screws. Verify the switch action by listening to and watching the switch contacts, using a volt-ohm meter between the proper sides of the switch, or by observing the controlled device. 1. Turn each setpoint dial to a temperature above ambient.

4. Insert the dial stop pin in the appropriate hole on either (or both) side(s) of the control dial to restrict dial rotation. Figure-6 Dial Stop Pin Insertion. Maintenance Open areas at bottom and around base of thermostat should be kept clean and free from obstructions to allow proper flow of air. If switch contacts need cleaning, this may be done with a contact burnishing tool (TOOL-13). Field Repair These thermostats are not field repairable. Replace the entire device.
