at the RETURN sensor when the OR OVR input is closed.

Displays method of operation: HeatNet (H-Net)
H-Net MASTER
YES
Auto detected, based on the HEADER sensor.
If the HEADER sensor is present and is set to TYPEZ, the KN-
Series control is run as a H-Net MASTER (YES).
If the HEADER sensor is not TYPEZ, H-Net MASTER = NO.
MASTER TYPE
AUTO
AUTO, MIXED, DHW
Two PID controls are provided, one for Space heating and one for
DHW heating. This menu item selects how they are to be used. The
MASTER TYPE setting is used to determine if the MASTER
control is to be used as a space heating control, a mixed DHW/space
heating control, or just to perform DHW Heating.
When set to AUTO, the boiler uses one PID control to provide space
heating. When set to MIXED, the control will use two independent
PID controls to provide space heating and DHW heating. When set
to DHW, the control only uses the DHW PID control.
H-NET ADDRESS
255
(2
–16)
The local address is the address of a member device.
This is
normally in the range of 2 through 16. But if the KN-Series control
is a MASTER, then the default address is 255. The H-NET
ADDRESS # is synonymous with boiler #.
MODBUS ADDRESS
1
(1
– 247)
The MODBUS address is for communicating with Laptop, PC, or
other MODBUS capable device, such as a Building Management
System. It is the 2nd communication port reserved for host control.
MODULAR BOILER SET
SPACE HEATING
DHW HEATING
If the MASTER TYPE is set to MIXED, or the DHW BOILER?
setting is set to LOCAL or MIXED, the MODULAR BOILER SET
is duplicated for each PID. Select SPACE HEATING to set the
ADD, SHED, MODULATE, and MOD MAX values for the space
heating PID. Then select DHW HEATING to set the ADD, SHED,
MODULATE, and MOD MAX values for the DHW heating PID.
ADD BOILER DELAY
10mins
(0
– 15min)
This is the delay time in 30sec intervals, before starting a new boiler.
Boiler #1 is started immediately after a call for heat. If a second
boiler needs to start, the ADD BOILER DELAY will need to expire
before starting.
SHED BOILER DELAY
2mins
(0-15min)
This is the delay time in 30 second intervals, before stopping a
