**NOTE: Alarm will stop once the cause of the alarm is corrected.
P1, P2, P3, P4, P5, P6 = Open/Disconnected NTC Thermistor or Temperature/Humidity Sensor
L1, L2, L3, L4, L5, L6 = Low Temperature Alarm (Sensed temperature is below X degrees F below setpoint for over 30
minutes)
H1, H2, H3, H4, H5, H6 = High Temperature Alarm (Sensed temperature is above X degrees F above setpoint for over
30 minutes)
r5, r6 = Open/Disconnected Humidity Sensor
d1 = door open alarm
Troubleshooting - To troubleshoot, check all connections and using a multimeter check resistance values.
