In many cases, problems like power outages, thermostat miscommunications, or minor glitches can be resolved by following the simple reset procedure as outlined in this guide. Downloadable to see if the control PCB is still useable by leave the faulty component of the control PCB and doing the communication test on the outdoor side of the system, there is a chance that the faulty component hasn’t taken the control PCB with it. Communicating Outdoor Units Only) In heat pump applications, the electric heat is staged to provide supplemental heat to meet desired comfort levels. The Inverter Heat Pump must be positioned on a concrete base. By doing this, the unit is able to maintain a set temperature.
