USER INFORMATION
and the unit will defrost itself. This unit features Adaptive Demand Defrost that monitors ambient and coil temperatures to regulate the defrost function accordingly.
At the beginning of the defrost cycle, both the outdoor condenser fan and compressor will turn off. After approximately 30 seconds, the compressor will turn on and begin to heat the outdoor coil causing the ice and snow to melt. NOTE: While the ice and snow is melting, some steam may rise from the outdoor unit as the warm coil causes the melting frost to evaporate.When defrost is completed, the outdoor fan motor will start, and the compressor will turn off again. In approximately 30 seconds the compressor will start up again and continue normal operation.
Operating the Heat Pump for Automatic Cooling and Heating
1.Set the thermostat system switch to AUTO and the thermostat fan switch to AUTO. See Figure 1.
Note: Thermostats will vary. Some models will not include the AUTO mode, and others will have the AUTO in place of the HEAT and COOL, and some will include all three.
2.Set the thermostat temperature to the desired heating and cooling temperature level(s).The outdoor unit and the indoor blower will then cycle on and off in either the heating or cooling mode of operation as required to automatically maintain the indoor temperature within the desired limits.
Operating the Indoor Blower Continuously
The continuous indoor blower operation is typically used to circulate the indoor air to equalize a temperature unbalance due to a sun load, cooking, or fi replace operation.
Set the thermostat fan mode to ON (Figure 1). The indoor blower starts immediately, and will run continually until the fan mode is reset to AUTO.
The continuous indoor blower operation can be obtained with the thermostat system mode set in any position, including OFF.
Shutting the Heat Pump Off
Change the thermostat’s system mode to OFF and the fan mode to AUTO. See Figure 1. NOTE: The system will not operate, regardless of the temperature selector setting.
