Operation
Overview of display values and settings
Start-up relief
ON: SOLID FUEL-T > T- RELAY 1
OFF: SOLID FUEL-T < [T- RELAY
1 - 5K]
The pump is switched on when the
temperature of the heat generator for
solid fuel exceeds the temperature of
the buffer storage at the inlet area
(BUFFER-T-LOW) by the hysteresis
(HYST 5K). Switching off
occurs when the temperature drops 5K
below the switch-on temperature.
Switching off additionally occurs when
the temperature of the heat generator
for solid fuel drops below the set limit
temperature (T-RELAY1) by 5K. The
pump is enabled again when the
temperature of the heat generator for
solid fuel exceeds the set limit
temperature (T-RELAY1).
Disabling the HS1
ON: SOLID FUEL-T +5K > SET
HS-T and solid fuel boiler
pump = ON
OFF: SOLID FUEL-T < SET HS-T
or solid fuel boiler pump
= OFF
!
Disabling the HS1 only occurs if
the solid fuel boiler is integrated in
the HS1 controller.
If the cooling function is activated,
it will also affect the solid fuel boiler
function.
23 = Solar integration
T-COLLECTOR = Temperature of the
solar collector BUFFER-T-LOW =
Temperature of the storage tank at the
inlet area (connector III, pin 2+3)
ON:
T-COLLECTOR >
[BUFFER-T-LOW + HYST
RELAY 1 + 5K]
OFF: T-COLLECTOR<
[BUFFER-T-LOW
+ HYST
RELAY 1]
The pump is switched on when the
temperature of the solar collector
exceeds the temperature of the
buffer storage at the inlet area
(BUFFER-T-LOW) by the hysteresis
(HYST 5K). Switching off
occurs when the temperature drops 5K
below the switch-on temperature.
26
Safety / system protection
OFF: T-PUFFER-T-LOW >
T- RELAY1
ON: BUFFER-T-LOW < [T- RELAY
1 - 5K]
Switching-off occurs when the
temperature of the storage tank at the
inlet area exceeds the set limit
temperature (T-RELAY1). The pump is
enabled again when the storage tank
temperature drops below the limit
temperature by 5K.
24 = return flow temperature
increase
RETURN-TEMP = Return temperature
of system
ON:
RETURN TEMP < T- RELAY1
OFF: RETURN TEMP > [T- RELAY
1+ HYST RELAY 1]
The return flow temperature increase
pump is switched on if the return flow
temperature drops below the set limit
temperature (T-RELAY1). It is switched
off again when the return flow
temperature exceeds the set limit
temperature by the Hysteresis (HYST
RELAY1).
32 = Direct heating circuit
Is activated by means of a short circuit
at the sensor input of relay 1 and
switches the heating circuit pump ON.
There is an after-run after the sensor
short circuit is cancelled. The HS
obtains a set temperature value from
the parameter "T-RELAY 1“.
RELAY FUNC 2 (function selection
relay 2)
00 = no function
01 = Header pump
ON: When heat is requested by a
consumer
OFF: Without consumer heat request
If at least one consumer in the system
requests heat the pump is switched on.
The after-run function is effective after
the heat generator is switched on.
02 = Circulation
Switching the relay according to the
circulation program
03 = Booster pump
ON: In the event of a heating request
from an internal consumer
OFF: Without internal consumer
heating request A pump after-run
occurs.
05 = Pump heat generator 1
When using the controller to control
two heat generators the relay may be
used to control the heat generator
pump for heat generator 1.
(Relay switches with burner relay 1;
run-down =5 min)
06 = Pump heat generator 2
When using the controller to control
two heat generators the relay may be
used to control the heat generator
pump for heat generator 2.
(Relay switches with burner relay 2;
run-down =5 min)
