Description
First digit (2nd circuit):
• DO NOT CHANGE parameter 34 first dig-
it. Second central heating circuit operation
is not currently supported .
• 0 (2nd CH circuit off ) - No second CH
circuit operation (LEAVE AS IS)
• 1 (2nd CH circuit as slave)
• 2 (2nd CH as master)
• 3 (2nd CH circuit as slave, T set also by
potmeter) - 2nd heating circuit as slave,
with setpoint temperature with setpoint
temperature determined by potentiometer.
• 4 (2nd CH circuit as master, T set also by
potmeter) - 2nd heating circuit as master,
with setpoint temperature determined by
potentiometer.
4
• 5 (2nd CH circuit as slave, active during
HW) 2nd heating circuit as slave, during
DHW.
• 6 (2nd CH circuit as slave, active during
HW) - 2nd heating circuit as master, during
DHW .
• 7 (2nd Ch circuit as slave, T set also by
potmeter, active during HW) - 2nd heating
circuit as slave, during DHW, with setpoint
temperature determined by potentiometer.
• 8 (2nd CH circuit as master, T set also by
potmeter, active during HW) - 2nd heating
circuit as slave, during DHW, with set point
temperature dtermined by potentiometer.
Second Digit (CH Type):
• 0 (room thermostat) - Central heating
opertion controlled by room thermostat
• 1 (outside temperature) - DO NOT SE-
LECT - Central heating operation con-
trolled by outside sensor (not currently
supported)
• 2 (0 - 10 V analog on MCBA: Capacity)
- DO NOT SELECT - central heating boiler
input controlled with 0 - 10 V input to con-
trol module (not currently supported)
• 3 ( 0 - 10 v analog on MCBA: temperature)
- DO NOT SELECT - Central heating boiler
outlet temperature controlled with 0 - 10
vdc input to control module (Not currently
2
supported)
• 4 (0 to 10 V analog on HAM: capacity) -
Select this value when using HAM module
to interface with multiple boiler controller.
See HAM instructions.
• 5 ( 0 - 10 V analog on HAM temperature)
- DO NOT SELECT - Central heating boiler
outlet temperature controlled with 0 - 10
vdc input HAM module, but controls tem-
perature setpoint. See HAM instructions.
• 6 (+/- control) - DO NOT SELECT - Cen-
tral heating mode controlled with +/- input to
control module (not currently supported)
