DISPLAYING TEMPERATURE SENSOR #2
Sensor number 2, the air outlet or evaporator 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 evaporator air inlet temperature) after 60 seconds. Both sensors can also be read through the
Ethernet and USB connections with the optional communications board.
COMPRESSOR RESTART TIME DELAY
A factory set 5 minute (300 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. If the time delay is reduced to less than five (5) minutes, this may cause reduced compressor life.
ALARM OUTPUT CONTACT
The smart controller has a normally open dry contact alarm output with a resistive load rating of 250 VAC at 3
amps. A connector located on the enclosure side of the unit provides a 2 pin connection to this output marked
YEL/ALARM.
ALARM INPUT CONNECTION
The smart controller can accept a dry contact/switch input via the connector terminals marked WHT/DS1 and
WHT/DS2 located on the enclosure side of the unit. This input is associated with the controller display alarm
mnemonic TP (door open and/or smoke detected). To use this feature, remove the jumper wire connecting
terminals DS1 and DS2 and replace with customer supplied wires from the enclosure door switch to DS1 and DS2
terminals.
ALARM CONDITION DISPLAY
There are seven possible non-latching alarm conditions detectable by the controller and are indicated on the
controller display. All alarms can also be accessed through the Ethernet and USB connections with the optional
communications board.
