Celsius Programming 
Celsius Programming option allows the user to control the DELTA-T Air Conditioner in SI units. This 
feature can be programmed into the digital temperature controller at time of manufacturing. This 
feature is also available as an upgrade to air conditioners already in the field equipped with Gen 2.0 
controller via a flash drive key. 
External Heat Output 
This option allows you to add an external heater to be located anywhere in your enclosure. These 
external heaters are ideal for focusing on individual sections of the enclosure without having a large 
capacity Built-in Heater. 
External Heater capacities available are 100 Watt, 150 Watt, 200 Watt, 250 Watt, 300 Watt,  
400 Watt, 550 Watt, 650 Watt & 950 Watt 
    Default Settings: 
  55°F Heat Set Point 
  3°F Differential 
At the default settings the heater output turns on at 52°F and operates until the temperature has 
reached 55°F. Refer to Advanced Digital Temperature Controller Programming section on this manual 
for details on changing these parameters. 
Special Programming 
All DELTA-T 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. 
High Ambient 
Most of our air conditioners have capabilities for high ambient application upgrades from our Standard 
Maximum Ambient temperature of 125°F. With this option we can optimize the Air Conditioner during 
manufacturing to achieve improved performance at high ambient conditions. 
Open Door Kill Switch 
This option provides you with an adjustable and mountable safety switch for your electronics 
enclosure. This switch will disable power to the air conditioner when your electronics enclosure door is 
open allowing you to work on your enclosure without the risk of unintentionally powering the unit. 
Adjustable Temperature Probe 
The adjustable temperature probe provides you with a 5’ temperature probe that can be installed 
anywhere in your enclosure. This allows you to have the flexibility to monitor and maintain the 
temperature at any specific location of your enclosure.
