P1-1 Heaters Turned Off
Heater is then turned off. After 10 seconds, the current draw is measured. The change in current draw is
then recorded.
Test passes if change in current draw test is in the range specified.
Condenser Fan Current Draw:
For P2 tests, the condenser fan is turned on, then off. Current draw must fall within
specified range. No other system components will change state during this test. If the Water Pressure Switch is
open this test will be skipped.
P2-0 Condenser Fan On
Condenser fan starts in the off condition and current draw is measured. Condenser fan is then turned on
and after 15 seconds the current draw is measured again. The change in current draw is recorded.
Test passes if change in current draw test is in the specified range.
P2-1 Condenser Fan Off
Condenser fan is on and current draw is measured. Condenser fan is then turned off and after 10
seconds the current draw is measured. The change in current draw is recorded.
Test passes if change in current draw test is in the specified range.
Low Speed Evaporator Fan Current Draw:
For P3 tests, the system must be equipped with a low speed
evaporator fan, as determined by CnF02, the Evaporator Fan Speed Select configuration variable. Low speed
evaporator fan is turned on, then off. Current draw must fall within specified range. No other system components
will change state during this test.
If a unit is configured for single evaporator fan operation and either AL11 or AL12 is active at the start of either test,
then the test will fail immediately. If AL11 or AL12 become active during the test, then the test will fail upon
conclusion of the test.
P3-0 Low Speed Evaporator Fan Motors On
Low speed evaporator fans start in the off condition and current draw is measured. Low speed evaporator
fans are then turned on and after 60 seconds the current draw is measured again. The change in current
draw is recorded.
Test passes if change in current draw test is in the specified range.
P3-1 Low Speed Evaporator Fan Motors Off
Low speed evaporators are on and current draw is measured. Low speed evaporator fans are then
turned off and after 10 seconds the current draw is measured again. The change in current draw is
recorded.
Test passes if change in current draw test is in the specified range.
High Speed Evaporator Fans Current Draw:
For P4 tests, high speed evaporator fans are turned on, then off.
Current draw must fall within specified range and measured current changes must exceed specified ratios. No
other system components will change state during this test.
If a unit is configured for single evaporator fan operation and either AL11 or AL12 is active at the start of either test,
then the test will fail immediately. If AL11 or AL12 become active during the test, then the test will fail upon
conclusion of the test.
P4-0 High Speed Evaporator Fan Motors On
High speed evaporator fans start in the off condition and current draw is measured. High speed
evaporator fans are then turned on and after 60 seconds the current draw is measured again. The
change in current draw is recorded.
Test passes if change in current draw in the specified range AND measured current changes exceed
specified ratios.
If the three phase motors are configured IN, the change ratio test is skipped.
