Supplies List
Basic accessories for the controller are included, however, certain truck stock items are required to complete the installation.
- stock items are required to complete the installation.
- Conduit to go between the controller and the evaporator (high & low voltage).
- Conduit connectors (straight or elbow as required).
- High voltage wires matched to the load of the heaters, fans, liquid line solenoid, and the controller (for ease of install consider using the KE2 Wire Harness accessory).
- Spade Connectors matched to the gauge of the high voltage wires.
- Wire labeling (numbers, colors, etc.).
- Additional wire ties.
- 18 gauge twisted shielded pair, if extending sensor wires.
- Foam insulation, if running wires outside the space.
- Silicone (for sealing any box penetrations).
Popular Accessories
The following parts are available separately:
- KE2 Wire Harness – 10’ pn 20736, 25’ pn 20670, 40’ pn 20737
- Door Switch – pn 20543
Further information on accessories can be found in the KE2 Condensed Catalog 411.
Controller Webpages
The controller has a built-in webpage for service. The webpage can be accessed multiple ways, including: plugging the controller into a KE2 Therm communication accessory like the KE2-Edge Manager (KE2-EM), connecting the controller to a network/provide it internet access, using the KE2 Service Tool App with an Ethernet dongle, or by plugging a laptop directly into it. Once on the webpage, logging in is required to make changes.
- The defaults are: User Name: ke2admin Password: ke2admin
- IMPORTANT: The password MUST be changed from the default upon logging in for the first time for security purposes.

Installation Steps
Installation consists of mounting the panel, wiring the high voltage connections, wiring the low voltage connections (sensors, transducer & EEV if used), and inputing the initial setpoints
High Voltage Wiring – Wiring Schematic
w/ KE2 Terminal Board & Wiring Harness
Sensor Installation – Return Air Temp Sensor
Install the air temp sensor using the air sensor mount E , approximately
2/3 down from the top of the evaporator, and 8 – 12 inches from coil in the
return air of the evaporator.
We recommend standardizing for all installations
**Green (Aux1) & Yellow (TCoil) for Coil Sensors
**
**Blue (TAir) for Air Sensor

Sensor Installation – Coil Temp Sensors
IMPORTANT: Determine coil sensor locations When arriving on site, put the
system into defrost, verify all heating elements are working properly, and
observe where frost is last to disappear on the coil. Place one sensor in each
of the last two places where frost disappears ❶
To prevent sensor wire damage from sharp edges, insert plug (D) into coil
housing – ❷. Plug is inserted in the inner housing to access the coil.
Puncture plug to insert sensor wire.
For most applications, the sensor should rest against a circuit tube in
between the evaporator fins ❸. Position the sensor vertically between the coil
fins. Pinch fins together gently all around the probe, securing the sensor.
This also provides thermal ballast, ensuring a complete defrost. Don’t locate
the sensor next to heating elements or insert the sensor too far into the
coil. Leave a handloop for service in-case the sensor must be repositioned
Intro Mode
The controller will enter Intro Mode the first time power is applied. Intro Mode consists of as little as 4 setpoints that must be configured to begin controlling the system
- Press or to move through the available Types of Control. Once the correct option is displayed, press and hold ENTER for 3 seconds.
- . If AdE or EdE was selected, the controller asks for the Expansion Valve Type and displays rS. Press or to scroll through the available expansion device types. With the correct EEV displayed, press and hold ENTER for three seconds.
- f AdE or EdE was selected, the refrigerant must also be selected. Press or scroll through the available refrigerants. Press and hold ENTER to save a selection.
- The final prompt is to set KE2 SMARTACCESS to ENABLED or DISABLED. KE2 Smart Access allows you to easily view and modify your controllers online. Press or to make your selection, then press and hold ENTER
Note: If a KE2-Edge Manager (KE2-EM) is on site, select DISABLED for KE2 Smart Access.
