8.2.2 Wiring the Programmable Wall Control to a KE4 Heater
The Programmable control backing plate has 8 terminal points for the connection of control
wires. When connecting, use ONLY the two top terminals marked RH and W. Ensure that the
IMPORTANT R (RH) and W polarity is correct at both ends of the wire cable. DO NOT remove the factory
fitted link between RH and RC.
A Kaden Programmable Wall Control can be wired directly to a Kaden KE4 heater as follows:
•
Run a twin wire cable (i.e. figure 8 cable - 0.75mm2) from the heater to the Programmable Wall Control.
•
Remove the backing plate from the Programmable Wall Control by unclipping it at the sides.
•
Draw the wires from the wall cavity and feed them through the opening in the backing plate.
•
Connect the cable to the terminal connections on the backing plate before mounting it to the wall refer to
Diagram 19.
•
Mount the backing plate onto the wall and then reassemble the controller.
•
Feed your cable through the grommet located at the base of the unit underneath the access panel.
•
Connect the other end of the cable to the terminals marked R and W in the heater's electronic control module,
refer to Diagram 19.

8.2.3 Wiring Programmable Wall Control to KU3, KE3 & KE4 for ADD-ON Cooling
The KU3, KE3 and KE4 heater control board does not have provision for "Add-On" cooling operation. For "Add-
On" cooling operation the unit must be configured, by fitting an Add-On Cooling Relay.
To facilitate Add-On Cooling operation, Kaden accessory Part No. 1621344 must be fitted.
8.3 MANUAL WALL CONTROL INSTALLATION
8.3.1 Wiring the Manual Wall Control to a KU3 Heater
The Manual control backing plate has 8 terminal points for the connection of control wires. When
connecting, use ONLY the two top terminals marked RH and W. Ensure that the R (RH) and W
IMPORTANT polarity is correct at both ends of the wire cable. DO NOT remove the factory fitted link
between RH and RC.
A Kaden Manual Wall Control can be wired directly to a Kaden KU3 heater as follows:
•
Run a twin wire cable (i.e. figure 8 cable - 0.75mm2) from the heater to the Manual Wall Control.
•
Remove the backing plate from the Manual Wall Control by unclipping it at the sides.
•
Draw the wires from the wall cavity and feed them through the opening in the backing plate.
•
Connect the cable to the terminal connections on the backing plate before mounting it to the wall refer to
Diagram 20.
