If wall thermostat closes during this delay, TDR is reset and fan relay remains energized. TDR is a 24-v device that operates within a range of 15-v to 30-v and draws about 0.5 amps. If the blower runs continuously instead of cycling off when the fan switch is set on AUTO, the TDR is probably defective and must be replaced. XII. LOSS OF CHARGE SWITCH The loss of charge switch is located on the outdoor liquid line. This switch contains a Schrader core depressor. This switch opens at 7 psig and cl

A freeze protection thermostat (FPT) is located on the indoor coil. It detects frost build-up and turns off the compressor(s), allowing the coil to clear. Once frost has melted, the compressor can be reenergized. 11 CONTROLS (cont) Heating, Units Without Economizer — With unit main power on, set thermostat at HEAT position and desired room temperature.

These heat pump systems provide economy of operation through energy conservation. They recover heat for indoor comfort from outdoor air during the heating season and, by automatically reversing the refrigerant system, remove indoor heat and excess humidity during the cooling season. All models are ARI certified. FEATURES COMPRESSOR—Designed specifically for heat pump duty, with high energy efficiency during heating and cooling operation. Each compressor is hermetically sealed against contamina
