ALARM PARAMETERS

P19 40 F Low Temperature Alarm

DISPLAYING TEMPERATURE SENSOR #2

Sensor number 2, the air outlet or condenser coil sensor, can be viewed at any time by pressing the up or down

arrow button on the front panel of the controller display. The display will revert to displaying temperature sensor

number 1 (the AC inlet temperature) after 60 seconds. Both sensors can also be read through the Ethernet and

USB connections.

COMPRESSOR RESTART TIME DELAY

A factory set 6 minute (360 second) restart delay exists to reduce residual back pressure before allowing the

compressor to restart. The compressor will stay off for the entire restart duration after the compressor is

disabled. A flashing “1” on the controller display will indicate the unit is in a compressor restart delay while

calling for cooling.

ALARM OUTPUT CONTACT

The Remote Access Control has a normally open dry contact alarm output with a resistive load rating of 250 VAC

at 3 amps. Two yellow 18 AWG wires located at the back of the air conditioner provide a connection to this output.
