Options
The NE040-D48 Series Air Conditioners may be ordered with the following options. Review the list
below for the specifications and functions of the option(s) that apply to your unit.
Dry Contact
This option provides an early warning capability to your enclosure to aid in the protection of your
expensive equipment. The Dry Contact is programmed with an individual dry contact set point to
monitor the enclosure temperature limit that you require. When the enclosure temperature has
exceeded the maximum limit, the Form C gold plated contact will activate to notify you that there is a
problem in achieving your cooling set point.
Default Settings:
105°F Dry Contact High Temperature Alarm Set Point
2°F Recovery Differential
3min Temperature Alarm Delay
At the default settings the Dry Contact initial conditions are normally open and/or normally closed.
When the unit is powered on and the temperature exceeds 105°F for a period longer than 3 minutes
the Dry Contact will activate. At this time the normally open contact will close and the normally closed
contact will open. This state will remain until the temperature has decreased to 103°F.
Note:
The dry contact is not a power status indicator, rather a high temperature alarm alerting you that
the unit is unable to meet the cooling set point.
Refer to Advanced Digital Temperature Controller Programming section on page 8 for details on
changing these parameters.
Special Programming
All Thermal Edge Air Conditioners have a Special Programming option for selecting unique pre in
programmed settings for special requirements. Although most parameters are accessible in our digital
controller, this option allows you to receive a unit preset to your requirements without the need to
manually configure the unit. Refer to Advanced Digital Temperature Controller Programming section
for details on all default settings.
