Alarms (KE2 LDA). See page 4 for additional details.
Service Call Saver - Post Defrost Indicator
To eliminate unnecessary service calls, the KE2 Temp + Valve alerts the
user when it is coming out of a defrost cycle using the onboard dis-
play. 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.

Installation Manual
When wiring the controller rst remove the display by loosening the
four corner screws. The display is connected to the lower board by a
short ribbon cable.
Caution: The board may be damaged if excessive force is used when
removing the cover.
1
Wiring the Controller
The Temp + Valve was designed with functionality in mind. The con-
troller accepts 120V / 208-240V to power the controller and 12V -
240V solenoid voltage via the liquid line solenoid relay through the
lower conduit connection. The temperature sensor, pressure trans-
ducer, valve, and communication wires are attached via the upper
conduit connector.
After the four screws have been detached from the lower section, the
cover may be gently moved to the side.
2
Next remove the high voltage protective cover. There are two screws
holding it in place.
3
With the high voltage cover removed, the two screw terminal con-
nectors can be seen. The Red 2-position connector is the controller’s
power supply.

7Replace high voltage shield after wiring is completed.
The liquid line solenoid/compressor relay accepts a variety of input
voltages and is not required to match the controller’s input. See table
for relay ratings. The relay uses the 3-position screw terminal to make
the connection on the board. This relay is designed to control smaller
compressors directly. It may also control either the liquid line sole-
noid or as a pilot to the compressor contactor. When connecting the
wires to the relay, the controller will be breaking one leg of the power.
One leg of incoming power (L1) supply for the liquid line solenoid
should be connected to the common terminal of the liquid line sole-
noid relay, the right most terminal connection. The other leg of the
incoming power (L2) should be connected directly to the solenoid
lead. The remaining lead from the solenoid should be connected to
the NO (normally open) terminal, the left most terminal location.
Proper wiring practices must be followed. Local wiring codes take
precedence over any information in this bulletin.

Installation Manual
Remote Monitoring, Control, Alarm Notications
The KE2 Temp + Valve includes RS-485 Modbus communications, and
can now be accessed remotely using the KE2 Local Area Dashboard
and Alarms (KE2 LDA). See page 4 for further details.
Low Voltage Connections
Air Temperature Sensor - The air temperature sensor terminal is
located on the cover’s circuit board, and is permanently attached.
The temperature sensor input consists of the right two terminal posi-
tions. Although the terminals are labeled‘+’and‘ -‘ , the sensor is not
polarized and may be connected in either orientation.
The sensor should be fed through the top conduit connection, be-
fore being attached to the board.
Suction Temperature Sensor - The suction temperature sensor
terminal is located on the cover’s circuit board, and is permanently
attached. The temperature sensor input consists of the middle two
terminal positions. Although the terminals are labeled ‘+’ and ‘ - ‘ , the
sensor is not polarized and may be connected in either orientation.
The suction temperature sensor is required when applying the con-
troller with an electronic expansion valve. The sensor’s proximity
to the evaporator outlet diers slightly for electronically controlled
valves from the placement of a TEV bulb. Due to the more rened
control from an electronically controlled valve, the sensor must be
placed as close to the outlet of the coil as feasible.
Although the distance from the outlet is dierent, the nature of the
refrigerant’s ow through the tube remains unchanged, thus the ori-
entation of the sensor remains at the 4 or 8 o’clock position. The sen-
sor should be secured to the suction line using the included wire ties
designed or low ambient operation.
Pressure Transducer – The pressure transducer terminal is located
on the cover’s circuit board, and is permanently attached. The pres-
sure transducer input consists of the 3 terminal positions on the left-
hand side of the board.
The pressure transducer can be attached to the suction service port
on the evaporator’s suction header. If a suction port is not available,
mount the pressure tap on the top of a horizontal section of tube, ap-
prox. 3 inches downstream of the suction temperature sensor.

Installation Manual
Accessing the KE2 Temp + Valve on a Local Area
Network
When the KE2 Temp is connected to the KE2 LDA communication
device’s serial USB adapter, the device will find the controller, and
provide immediate local network communication. More informa-
tion on the KE2 LDA is found in bulletin Q.5.42.
Accessing the KE2 Temp + Valve on the Internet
When used with the KE2 LDA, the KE2 Temp + Valve
can be accessed remotely through the KE2 Smart
Access portal, anywhere Internet service is avail-
able. So, there’s no need to worry about your re-
frigerated products overnight, during holidays,
or vacations. Just go online and see, or setup the
email/text alarm alerts feature, for instant notifica-
tion of system issues. More informa-
tion on KE2 Smart Access is found in
bulletin Q.1.34 and A.1.76.
Webpage View
From the Webpage you can monitor temperatures, relay status
and alarms, as well as make changes to setpoints, and manually
control the system.

Programming the Controller
Many applications can use the controller’s preset defrosts per day.
This automatically spaces the defrosts throughout the day, based
on the number of defrost cycles selected. The user can change the
number of defrost cycles performed by changing the Defrost per Day
setpoint, ranging from 0 to 12. Or, if required, each individual defrost
can be scheduled for a specic time of day.
