Installation Manual

Supplies List

All of the accessories required for the controller to work

are supplied, however, standard truck stock items are re-

quired to install the controller. A list is provided below:

conduit to go between the controller & evaporator

(2) conduit connectors (straight or elbow as required)

(4) high voltage wires matched to the load of the

liquid line solenoid/compressor and the controller.

wire labeling (numbers, colors, etc.)

additional wire ties

18 gauge twisted shielded pair (if extending sensor

wires/adding communication)

foam insulation (if running wires outside the space)

silicone (for sealing any box penetrations)

This reference should remain on site with the installed KE2 Temp + Defrost controller.

Service Call Saver - Post Defrost Indicator

To eliminate unnecessary service calls, the KE2 Temp + Defrost alerts

the user when it is coming out of a defrost cycle using the onboard

display. The display alternates between dEF and the actual temperature

measured by the air sensor. This continues until the temperature has

reached setpoint, or for the amount of time set by dFt (Defrost Time)

whichever is shorter.
