Installation Manual 7602-443 COMMUNICATING, PROGRAMMABLE THERMOSTAT • 1.0 User Menu Settings • 1.1 OFFSETS If you find that the temperature displayed on the thermostat does not accurately represent the room temperature where the thermostat is located, this offset function compensates for the difference. The thermostat will apply an offset between what temperature the thermostat is measuring versus the temperature that is displayed. • Heat Controller, Inc.
7602-443 COMMUNICATING, PROGRAMMABLE THERMOSTAT Heat Controller, Inc. 1.4 DEMO MODE Demo mode is designed to showcase heat pump operation when the unit is connected to an above ground water loop with the supply air being blown directly over the water loop. Installation Manual The starting mode (heating or cooling) depends on the loop temperature at the time when Demo Mode is entered. The unit will operate in heating or cooling based upon the following algorithm. Start in Cooling Mode 1.4.
