8. WALL CONTROL INSTALLATION

Kaden heating systems can be controlled by various Kaden Wall Controls. The Wall Control is located inside
the house and is wired directly to the heater. The wall control monitors the house temperature, and switches the
system ON and OFF to maintain a set temperature. So it MUST BE positioned correctly.
•
Install in the living area: It is important that the Wall Control is placed in a position that will provide the most
accurate reading of the temperature, i.e. in the area most often used for family living.
•
Attach on an internal wall: The temperature difference on an external wall can also affect it, so always mount it
on an internal wall. Keep the hole in the wall for the wiring as small as possible to prevent draughts from within
the wall cavity affecting the temperature setting.
•
Get the height right: The Wall Control should be approximately 1500mm above floor level.
•
Avoid hot spots: Keep the Wall Control as far away as possible from warm air outlets, radiation from the sun,
fireplaces, radio and television sets or warm pipes and duct running in the wall behind it.
•
Avoid cold spots: Keep it as far away as possible from draughts caused by doorways, stairwells, windows or
return air inlets.
•
Avoid dead spots: Keep it away from areas of less than normal air circulation e.g. behind doors, in alcoves or
corners.
•
Interference from other electrical connections: Ensure the Wall Control and wiring are kept away from other
electrical, data and antenna cables. This includes keeping the Wall Control's wiring away from the spark igniter
loom within the heater's cabinet.
•
Use the right cable: Use a cable of 0.75mm² in cross section and less than 100m in length.
DO NOT install the wiring with the power turned on, as the fuse may blow, which would not be
covered under warranty.
NOTE
ONLY use Kaden Wall Controls, as any failure relating to a non-Kaden Wall Control will not be
covered under warranty.
ONLY use alkaline batteries in a manual Wall Control. Other types can cause unwanted operation
of the heater when the batteries reach the end of their life.
*
KU4 heaters are factory supplied with a Programmable Wall Control, if you are upgrading the
system to utilise Networker wall controls, then follow the instructions for the KU5 heaters.
8.1 NETWORKER INSTALLATION KU5
8.1.1 Wiring the Networker to a KU5 Heater
The Kaden Networker backing plate has 4 terminal points for the connection of control wires.
When connecting, use ONLY the two top terminals marked TW1 and TW2 or ONLY the two
IMPORTANT bottom terminals also marked TW1 and TW2. NEVER use a combination of top and bottom
terminals when connecting to a single appliance.
For example, a Kaden Networker operating a Kaden cooler and a Kaden heater would have the
two bottom terminals connected to the heater and the two top terminals connected to the cooler.
When there is more than one Kaden appliance connected to a Kaden Networker, always ensure
that the TW1 and TW2 polarity is correct at both ends of the wire cable.
Networkers can be wired directly to KU5 (KU4*) heaters as follows:
•
Run a twin wire cable (i.e. figure 8 cable - 0.75mm2) from the heater to the Networker.
•
Remove the backing plate from the Kaden Networker 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 Diagram 17.
•
Mount the backing plate onto the wall and then reassemble the controller.
•
Feed the cable through the grommet, located at a cabinet end.
•
Connect the other end of the cable to the terminals marked TW1 and TW2 on the heater's electronic control
module, refer to Diagram 17.
