*Three temperature sensors are provided. The controller requires a room
temp sensor (T2Air - blue) and a coil temp sensor (T3Coil - yellow) to
function properly. KE2 Therm strongly recommends the third sensor is
used as 2nd coil temp sensor (T4Aux - green).

IMPORTANT:
Determine the coil sensor location
When arriving on site, put the system into defrost and
observe where the frost on the coil disappears last.
Place the coil sensors in the two places where you ob-
serve the frost disappearing last - ❶. Monitor the coil’s
air entering and air exiting side. Often the last place frost
disappears is on the air exiting side, near the right or left
end. And, it is important to verify all heating elements are
working properly.
Generally, sensor location is approximately 1 to 1-1/2”away
from the right and left edges of the active coil surface, and
typically near the bottom 1/3rd of the evaporator. Ice tends
to grow from the edges inward. The sensor needs to be as
far away from the defrost heat sources as possible. Do not
install on U-bend.
Note: To prevent sensor wire damage from sharp edges,
insert plug G into coil housing - ❷. Plug is inserted in the
inner housing to access the coil. Puncture plug to insert
sensor wire.
❸Insert the sensor into the coil so it touches two circuit
tubes, with the tip touching one of the circuit tubes. Don’t
locate it next to the heating elements - position it half way
between the heaters if possible. ❹The probe is inserted
into the ns approx. 1/16” deeper than the stainless shield-
ing. Pinch the ns gently together, securing the sensor. This
provides thermal ballast, ensuring a complete defrost.
Typically last spots to defrost
Verify by initiating a defrost,
and observing last spot to clear.
❶
Typical sensor location
approx. 1-1/2”from end,
in the bottom third of coil.

Alternate method - As the defrost termination sensor, it is
important the sensor does not terminate defrost before all
frost is removed from the coil. In some installations, insert-
ing the sensor into the coil may position it too close to the
defrost heat source. An alternate method of positioning
places the sensor vertically between the coil ns, see ❺.
Pinch ns together gently, securing the sensor ❻.
Extending sensor wires
After the sensors are mounted, route them back to the
controller. If the wires must be extended, use 18 gauge
twisted shielded pair. Max. length for 18 gauge: 100ft.
When running the sensor wires back to the controller be
careful not to introduce noise. Noise occurs when sen-
sor wires are located near high voltage lines (dened by
UL as greater than 30V.) Do not run sensor wires in the
same conduit as high voltage lines.
If crossing a high voltage line, run the sensor wiring at
right angles to minimize noise.
