ALARM RECOVERY
……..
If the compressor is turned off due to an alarm, it will be able to restart after the AC anti short-cycle time delay.
(Parameter AC = 3 minutes)
Probe alarm P1 is cleared with no time delay after the fault is cleared.
Probe alarm P2 starts and stops with no time delay.
Temperature alarm HA automatically clears as soon as the temperature returns to below 105 °F (the ALU setpoint) -2°F = 103°F.
Temperature alarm LA automatically clears as soon as the temperature returns to above 45
°F (the ALL setpoint) +2°F = 47°F.
Temperature alarm HA2 automatically clears as soon as the condenser coils temperature returns to below 153 °F.
Temperature alarm LA2 automatically clears as soon as the condenser coils temperature returns to above 60 °F.
Temperature alarm CA automatically clears as soon as the pressure returns to normal.
