Kaden Installer's Manual
Ducted Gas Heaters

3.1.1 Damper Motor Connections

All KUN4 and KUN5 series gas ducted heaters come with four RJ12 socket connectors preconfigured for Belimo
24V damper motors.

3.1.2 RJ Socket Connections

The plastic cover on the PCB includes moulded cut-outs to enable access to the RJ12 socket. For each socket to
be used, press out and remove the cut-out and connect the RJ plug from the Belimo
If not a Belimo damper motor confirm suitability of the terminal on the damper motor before connecting to the RJ12
socket on the heater PCB. The RJ12 socket in Diagram 12 contains six terminal wires, the left two are connected
to Normally Open (N/O) on the 3-way terminal block, the middle two are connected to '0V', and the right two are
connected to Normally Open (N/C). Check the installation manual accompanying the damper motor to determine
if the RJ12 socket on the heater PCB is suitable.

3.1.3 RJ12 socket detail on heater PCB

Diagram 12 details the Normally Open (NO) and Normally Closed (N/C), Zero Volt (OV) and Normally Open (N/O)
connections for the RJ12 socket connections for zones A, B, C and D on heater PCB. These connections required
to enable the networker outputs to control the damper motors.
Note: Ensure that the circuits are correct to Diagram 11 as applicable.
