BUS TERMIN
This parameter is used to switch the terminal resistance for
Can communication. The entire system may contain exact-
ly one terminating resistor.
Delivery state:
Mixer controller (1124) => "00“
Boiler controller (0634, 0324,...) => "01“.
(Parameter BUS ID HS1 > 00 => BUS TERMIN = 00)
E When loading the factory settings, the terminal
resistance is newly set (according to boiler sensor).
EBUS SUPPLY (supply for eBUS)
Switching the eBUS supply on / off in relation to connected
devices (power supply balance) => see part 3:
Description of functions – eBUS burner controls.
AF SUPPLY (Outdoor sensor power supply)
Switching off the power supply to the outdoor sensor.
Switching off allows up to 5 controllers to be operated with
a single outdoor sensor. The power supply must only be
switched on if there is one controller per sensor = "01".
TIME MASTER
(Only without or TIME MASTER in system)
00 no time master => each heating circuit has its own time
01 controller is time master => all controllers and remote
controls take over the time settings of this controller.
! No more than 1 TIME MASTER is permitted in the
system!
DYN UPWARD (dyn. heat generator connection [K])
Small value = fast connection
Large value = slow connection
E Values set too low can lead to overheating or short-term
connection of a heat generator.
Calculation: If the cumulative system deviation in Kelvin
reaches the set value A, this results in connection of all
heat generator stages.
DYN DOWNWARD (dynamic heat generator deactiva-
tion [K])
Small value = fast deactivation
Large value = slow deactivation
E Values set to high can lead to overheating and
triggering the STB
Calculation: If the cumulative system deviation in Kelvin
reaches the set value A, this results in deactivation of all
heat generators.
RESET TIME (resetting time for I-Controller)
E Control value: Changing this value can cause the
control system to overshoot. The recommended default
settings should be retained.
