9.2 INSTALLER PARAMETERS CONTROL LCD SETTINGS
No. Display Appearance Description
1 HEATER MAXIMUM FAN SPEED SETTING
The number displayed is the fan's default fan speed setting i.e. the RPM the fan is set to
run at for normal heating operation. It can be adjusted between a maximum of 1350 and
a minimum of 500, and should be set to meet the installation's airflow requirements.
It is recommended to use a fan speed between 1000 to 1350, as lower speeds are more
likely to result in overheat conditions if the system has not been balanced correctly.
2 COOLING MAXIMUM FAN SPEED SETTING
This displays the RPM the fan is set to run at for normal refrigerative cooling. It can be
adjusted between a maximum of 1350 and a minimum of 500.
3 HEATER - ZONING MINIMUM FAN SPEED SETTING
This is the minimum RPM the fan will operate to with the maximum outlets closed due
to the Networker zoning in heating mode. The default is 950 but it can be adjusted
between a minimum of 500 and a maximum of 1350.
4 HEATER IDENTIFICATION NUMBER
(
DO NOT
alter unless multiple heaters are installed)
This parameter is used to identify each heater in priority order when more than one
heater is connected on the system.
5 CIRCULATION FAN OPERATION
This displays the RPM of the fan motor in circulation mode for fan operation between
heating / refrigerative cooling cycles. e.g. when the system achieves the set temperature
and is cycled off by the wall control, the heaters fan will continue to operate, to circulate
the room air.
6
SUPPLY AIR THERMISTOR SET POINT TEMPERATURE
This displays the temperature the heater's gas valve will modulate to maintain. The
default will vary across the different models, but can be adjusted between 45°C and
70°C. This should be set to provide a comfortable outlet temperature.
7
ZONE/REFRIGERATION MODE (NETWORK 516 MODULE & ON-BOARD RELAYS)
Selection modes for incorporating adaptive zoning and refrigeration onto the system.

On-board or Kaden Network or 516 Module relays can be
used for Heating only zone control (up to 3 with on-board
or 4 with Module).
2
On-board or Kaden Network or 516 Module relays can be
used for zone control (up to 2 on-board or 3 with Module)
for Heating and Add-On refrigeration.
3 Kaden Network 516 zone control (up to 3), for Heating only.
4
Kaden Network 516 zone control (up to 2), for Heating and
Add-On refrigeration.
5
Kaden Network 516 zone control (up to 4) for heating.
Add-on refrigeration control on heater PCB
8 SUPPLY AIR THERMISTOR SET POINT TEMPERATURE
This is the minimum RPM the fan will operate to with the maximum outlets closed due
to the Networking zoning in cooling mode.
DO NOT SET BELOW 1000
