Head Pressure Control
- Integral heat pump bypass circuity allows electronic bypass of speed control during heat pump operation
- Helps prevent evaporator freeze-ups, low pressure cut-outs & liquid-slugged compressors in low ambient conditions
- Eliminates overshoots common to on/off & pressure switch controls
- One models covers 120-480 VAC
- Features: hard start, low temperature cut off, high temperature bypass
- Requires 24 VAC supply
- Controls up to 3 refrigerant circuits
- Typical application: heat pumps or air conditioners
