Temperature Display on Cooling Unit
The temperature display provided on the cooling unit enhances the functionality of the NT
for wine cellar applications. Alarms trigger an audible alarm only at the cooling unit, the
alarms are not communicated through the NT. Consult the cooling unit Owner’s Manual
for detailed troubleshooting information related to these alarms.
The “Set” button has no effect since the set point is managed by the NT.
The following parameters and functions are not available with the NT configuration:
HY, FON, SET, HES, Quick Chill and Energy Saver.
For self-contained cooling units, high and low ambient temperature alarms
(“HA2”/”LA2”) will behave as follows (refer to the cooling unit’s Owner’s Manual for
addition information):
“HA2” alarm - the compressor will shut down until it cools off.
“LA2” alarm - will not shut down the unit and contact CellarPro asap.
A start up safety delay of 3 minutes is enabled when power is first supplied to the unit,
or when recovering from a power failure.
The defrost cycle will be managed automatically based on the unit configuration.
When the cooling unit is in defrost, “DEF” is shown on the display.
The power button can be used to turn off the unit. When the display reads “OFF”, the
compressor and fans are turned off, however the NT still has 24VAC power.
To completely shut down the system, turn off both the cooling unit and the NT, or
disconnect power to the cooling unit.
