HS2 Type
(second heat generator type => A7)
(For HS1 with 2-stage burner – not active)
00 = No secondary heat generator
01 = Single stage HS switching
08 = Cooling 1
20 = Solid fuel integration
(additional non-controllable HS)
for switching behaviour, see parameter HS2 storage
21 = Collector pump
22 = Pump for HS1 (e.g. additional HS for cascades)
Storage HS2
(heat accumulator for HS2)
(Only where HS2 Type = Solid fuel)
Warm-up relief applies superordinated:
ON: T-HS2 > Min T-HS2
OFF: T-HS2 < [Min T-HS2 – 5K]
T-HS2 = Solid fuel burner temperature
00 = Heating vis-à-vis collector (no storage tank) => F8
ON: T-HS2 > [F8 + Hyst Burner 2 + 5K]
OFF: T-HS2 < [F8 + Hyst Burner 2]
01 = Heating vis-à-vis buffer storage tank => F1, F3
ON: T-HS2 > [F3 + Hyst Burner 2 + 5K]
OFF: T-HS2 < [F1 + Hyst Burner 2]
02 = Heating vis-à-vis HW tank => F6
ON: T-HS2 > [F6 + Hyst Burner 2 + 5K]
OFF: T-HS2 < [F6 + Hyst Burner 2]
03 = Heating vis-à-vis STORAGE III (Pool) => F15
ON: T-HS2 > [F15 + Hyst Burner 2 + 5K]
OFF: T-HS2 < [F15 + Hyst Burner 2]
Switching pattern
The pump is switched on if the temperature of the solid
fuel boiler exceeds the temperature of the Reference
sensor by the hysteresis (Hyst Burner 2 + 5K). Switching
off occurs when the temperature drops 5K below the
switch-on temperature.
Warm up Temp
Switching off occurs when the temperature of the solid
fuel boiler drops below the set limit temperature
(Min T-HS2) by 5K. The pump is enabled again when the
temperature of the solid fuel boiler exceeds the set limit
temperature (Min T-HS2).
Buffer type
(heater buffer storage type)
!
After activation (01 or 02) it is not possible to
connect a FBR for heatcircuit 1.
00 = no buffer storage for heating operation
01 = Buffer storage for heating operation (F2, F3)
HS1 is activated with reference to sensor "buffer top" (F3)
DHW Relief operates on sensor
"upper buffer".
HW charge pump ON:
"Upper buffer" > HW 5K Hysteresis
HW charge pump OFF:
"Upper buffer" < HWactual
02 = Combination storage tank for heating and HW
operation
HS1 is activated with reference to sensor "buffer middle"
(F2)
DHW Relief operates on boiler sensor KF.
HW charge pump ON:
KF > HW 5K Hysteresis
HW charge pump OFF:
KF < HWactual
03 = passive buffer storage for heating operation (F1, F3)
The buffer will not load by the conventional Heat
generator producers. The use occurs, e.g., through solar
buffer loading [Buffer charging pump], [return flow
temperature increase] or [transfer pump for buffer
storage] (sensor usable).
In this attitude no change of the regulation of the heating
takes place in relation to the without buffers
Cooling mode (Space cooling via operating mode)
The mode of operation cooling and the necessary
settings are released. In the mode of operation cooling
the heating circles can be used for the cooling of the
room. For this function a refrigerating machine is
necessary.
Gradient
ON = HS1 Switching off for Gradient method
OFF = HS1 Switching off by set value + Hysteresis

„Switching behaviour of the HS with gradient method“
HC FUNCTION 1/2
(heating circuit function selection)
Standard => Standard heating circuit
T-Circuit Fxd => Control for fixed flow temperatures
During the heating periods (see heating program ) the
heating circuit is operated with a fixed preset flow
temperature
[T-Flow Day], and during reduced mode operation with a
fixed preset flow temperature [T-Flow Night] accordingly.
Pool => Pool control (only Heatcircuit 2)
This function can be used to heat a swimming pool. The
mixer controls the flow temperature for the swimming
pool heat exchanger. The sensor for the water
temperature of the pool is connected to the room sensor
connection for the heating circuit (see FBR) [connector
5+GND or 12+GND].
The flow temperature control operates like normal room
control [Room Influence].
The set value for the water temperature can be entered in
the user area of the associated heating circuit level
[T-Pool 1/2/3]. The heating program operates. No heating
takes place during the reduction period (frost protection
only).
The water temperature and the current set value are
displayed in the display level [T-Pool / T-Pool Desired].
HW => Hot water circuit
