ST ART -UP Preliminary Checks 1. Check that all internal wiring connections are tight and that all barriers, covers, and panels are in place. 2. Field electrical power source must agree with unit name- plate rating. 3. Ensure all service valves are open.
Should room temperature continue to fall, circuit R-W is made through second-stage thermostat bulb. If optional elec- tric heat package is used, a relay is energized, bringing on supplemental electric heat. When thermostat is satisfied, con- tacts open, deenergizing contactor and relay; motors and heat- ers deenergize.
