DISPLAYING TEMPERATURE DATA ON SCREEN

There are two temperature probes in the air conditioner where one is reading the enclosure air temperature
incoming to the air conditioner and other is reading the cooled air leaving the air conditioner and entering the
enclosure. Both temperature data are displayed on the screen where line 1 is the reading of the inlet temperature
and line 2 is the reading of the outlet temperature.

COMPRESSOR RESTART TIME DELAY

A factory set 3 minute (180 seconds) 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 compressor icon
mode while calling for cooling or waiting for compressor to turn ON.

ALARM INPUT CONTACT - DOOR OPEN/SMOKE DETECTED

The digital controller can accept a dry contact/switch input via the two 18 AWG white wires located at the back of
the air conditioner. This input is associated with the controller display alarm mnemonic dO (door open).
Note: Do NOT apply power to this dry contact input.
Para
H05 Door Open and/or smoke detected
ALARM OUTPUT CONTACT – ALL ALARMS
The digital controller has a normally open dry contact alarm output with a resistive load rating of 250VAC @
5 amps max. The two yellow 18 AWG wires located at the back of the air conditioner provide a connection to this
output. Note: Do not apply power to this normally open dry contact (two yellow 18 AWG wire). This alarm relay
output is configurable and provides user with the ability to change the configuration to support their external
device. Parameter C21 controls the alarm relay output logic and can be accessed through security code "0022" in
the PArF folder.
