                HEAD PRESSURE cONTROLS & TIME DELAYS
• Integral Heat pump bypass circuitry allows electronic bypass of speed control.
• eliminates 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 bypass, isolated 24 vaC supply.
• Controls up to 3 refrigerant circuits. • one model covers 120-480 vaC. • typical application: heat pumps. • 4.5” x 3” x 1.75”
  Input
• Control: 18-30 vaC, 50/60 hz. 1.8 va max • line Input: 120-480 vaC
output:
• triac max 10 amps, min 100 ma
One IcM model replaces:
• Hoffman: 800/800A/800A-A/814-50, 816-10 • Ranco: E31 Series
• Johnson controls: P66
• AcT: FM2000
