If the return air temperature is above +20C (68F), unit
operates in cool until the return sensor is less then +15C
(59F) or 1 hour.
If the return air temperature is below +5C (41F), unit
operates in heat until return temperature is above +5C
(41F) or 2 hours.

9.1A 9.0A 9.1A
With compressor and condenser fan on, compressor is
operating at 100 percent capacity. Amp draw is
measured and compared to voltage. Compressor
amperes are recorded in PTI log. 6, 7 20 seconds
DIGITAL VALVE TEST
AMB CON EVA
8.0C 25.0C 2.0C
9.1A 9.0A 9.1A
With compressor on - if condenser temperature is above
+30C (86F) condenser fan is turned on. Digital valve is
turned on then off. Amp draw difference is measured
and verified to be minimum 1.4 amps. 119 20 seconds
VAPOUR INJ. TEST
AMB CON EVA
8.0C 25.0C 2.0C
9.1A 9.0A 9.1A
With compressor on, condenser and evaporator fans
are turned on for 30 seconds. If condenser fan
temperature is below 30C (86F) then the test is aborted.
Vapor injection valve is turned on. Amp draw difference
is measured and verified to be minimum 0.4 amps.
26 50 seconds
COMP HI PRESS TEST

9.1A 9.0A 9.1A
With compressor on, evaporator fan operates on high
speed until high-pressure cutout occurs or condenser
temperature is above +70C (158F).
Condenser fan starts and operates until compressor
starts.

2.3A 2.1A 2.3A
With condenser fan on, compressor on, and evaporator
fans on high speed, cool capacity is set to 100 percent
capacity. Vapor injection valve is turned on. A difference
of approx. 4.5C (40.1F) is required between return and
supply air temperatures, depending on return air and
condenser coil temperatures. 22 3 minutes
