Head Pressure Control

• Integral heat pump bypass circuitry allows electronic bypass of speed control during heat pump operation
• Eliminated overshoots common to on/off and pressure switch controls
• Helps prevent evaporator freeze-ups, low pressure cut-outs,and liquid-slugged compressors in low ambient conditions
• Features:
• Hard start
• Low temperature cut-off
• High temperature bypass
• Isolated 24VAC supply
• Controls up to 3 refrigerant circuits
• Typical application: heat pumps
