Vapor Injection Control:
Modulation Cool or Power Limit
Vapor injection valve is energized (open) continuously when
the compressor duty cycle (ON time) is 100 percent (Full
Cool). High compressor discharge temperature may cause
the vapor injection valve to energize (open) but only while
the Compressor Digital Control valve is not energized
(closed).
Compressor Discharge Temperature Control:
Vapor Injection Valve Energizes (Opens) 138 C (280 F)
Vapor Injection Valve De-energizes (Closes)
6 C (10.7 F) below energize temperature
(132 C [123 F])
Compressor Shutdown (Auto Reset) 148 C (298 F)
Vapor Injection Valve (Compressor):
Voltage 24 Vac
Current 0.85 amps
Cold Resistance 5.6 ohms
Compressor Digital Control Valve:
Voltage 24 Vac
Current Draw 0.85 amps
Water Pressure Switch (Option):
Close 117 ± 21 kPa, 1.17 ± 0.20 bar, 17 ± 3 psig
Open 35 ± 21 kPa, 0.35 ± 0.20 bar, 5 ± 3 psig

Suction and discharge pressures vary too greatly during Modulation Cool to use for evaluating or diagnosing refrigeration
system performance. During the Modulation Cool mode, the suction pressure will vary between 100 and 450 kPa, 1.0 and 4.5
bar, 15 and 65 psig depending upon the percent (percent) cooling capacity.
**Discharge pressure is determined by condenser fan cycling.
