Explanation of the operating elements
Operation
8
Settings via DIP switch (rear side)
!
Settings 1-5 => In V1 without function
Sensor selection (5K NTC <-
> 1K PTC
)
Check the installed sensors (imprint, type plate, or
measurement value - see table) and set the switch
accordingly.
Functions
Functions
!
In V1, only stand-alone operation and operation with a
cascade controller/manager is supported
(also applies to individual heat generators).
Operation in the cascade
Function only with cascade manager via CAN BUS
Settings:
1/2/11/Mod = Depending on heat generator
BUS-ID = 01-88 (cascade)
Settings on the cascade controller:
HS1 Type = Cascade modulating or switching
HS1 BUS = CAN BUS
The controller can be used as a heating module for the
operation of switching and modulating (air damper) oil or
gas heat generators in cascades with 1 to 8 heat
generators (or 09-64 heat generators; only with
corresponding cascade managers). The controller can be
used to actuate any of the following configurations:
•
A single stage heat generator with associated
boiler pump and return flow temperature increase
via pump or mixer (1/2/11/Mod =1)
•
A two-stage heat generator with associated boiler
pump and return flow temperature increase via
pump or mixer (1/2/11/Mod =2)
•
A two-stage heat generator with associated boiler
pump and shared return flow temperature increase
via pump or mixer (1/2/11/Mod =11)
•
A modulating heat generator with associated boiler
pump (1/2/11/Mod =m)
Modulation in the cascade
In the case of a cascade, an air damper position is
assigned to the required degree of modulation. The air flap
is driven for the defined activation time => The mixer
OPEN/CLOSE relays (here air damper connection) are
actuated for the calculated period. => Only one qualitative
control process is performed (more/less output). The heat
generator will not deliver the exact degree of modulation
required.
!
The air damper activation time must be set under
switch position "
v
b
".
Air damper position:
0-10% = CLOSE; 100% = OPEN; Intermediate values in
increments
