6.2.3 "HC Configuration" level
Relay Test Manual control of individual relays for test purposes. After confirmation of this parameter with
the rotary button, the list of relays 1 - 9 is displayed with a checkbox on the display. For selec
-
tion and confirmation of a relay with the rotary button, a tick is placed in the checkbox and the
respective relay is activated. Multiple selection is possible.
Relay 1: Output J1 (internal heating circulation pump), output pump
Relay 2: Output J14 (circulation pump), Mix valve "Open"
Relay 3: Contact A on output J2 (3UVB1 switching valve), mix valve "Closed"
Relay 4: Contact B on output J2 (3UVB1 switching valve)
Relay 5: Output J12, 3UV DHW switching valve, "Closed"
Relay 6: Output J12, 3UV DHW switching valve "Open"
Relay 7: Connection J3 (potential-free relay: Closer B-B1) - AUX
Relay 8: Connection J3 (potential-free relay: Changer A-A1/A-A2) - AUX
Relay 9: Output J10 (A1P power supply)
* : When activating relay 3, relay 4 is switched on at the same time. When deacti-
vating relay 4, relay 3 is deactivated at the same time.

HC Function Various different functionalities can be assigned to the heating circuit.
0: Weather-dependent T-HS control
1: Regulation to a fixed set flow value, depending on the heating or setback mode
N E 0 - 1 0 1
Pump Mode Setting of the operating mode of the internal circulation pump.
0: Standard circulation pump switching (weather/room dependent)
1: Circulation pump switching according to heating limits (optional room thermostat shutdown
works additionally).
2: Circulation pump switching according to the heating program
3: Circulation pump switching in the continuous operation
N E 0 - 3 1 1
T-Outside lim day Only if [Pump Mode] parameter = 1:
Setting of the automatic summer switch-off of the heating operation. If the outside temperature
measured and averaged by the controller exceeds the set value by 1
K, the heating circuit is
switched off. The heating is released again if the outside temperature undercuts the set heating
limit.
E E Off, 10 - 40 °C 19 °C 1 K
T-Outside lim night Only if [Pump Mode] parameter = 1:
Setting the heating limit for the "Switch-off" of the heating circuit during the setback time (func-
tioning as in [T-Outside lim day] parameter).
E E Off, 10 - 40 °C 10 °C 1 K
Heat-Slope Only if [HC Function] parameter = 0:
Setting of the heat slope. The heat slope reflects the dependence of the target T-HS of the
heating circuit on the outdoor temperature (see chap.
3.6.2).
E E 0.0 - 3.0 0.5 0.1
Room Influence Only with room control connected and assigned to the heating circuit :
Setting that influences the deviation of the room temperature measured by EHS157034 from
the current target value (see chap.
3.4.3 and 3.4.4) has on the T-HS.
Off: Purely weather-dependent T-HS control
0: Purely weather-dependent T-HS control, but internal circulation pump continues running un-
til the next heating cycle after a heat requirement during the setback cycle.
1-20: Causes a correction of the flow target temperature (parallel shift of the heat slope) by the
set factor. If the measured temperature lies 2
K below the target value, the flow target temper-
ature is increased by 2x the set value.
E E Off, 1 - 20 K Off 1 K
T-Room Adj Only with room control connected and assigned to the heating circuit :
Individual adjustment of the room temperature relevant to the control unit.
If a systematic deviation of the room temperature measured by the EHS157034 to the actual
temperature in the occupied area of this room is determined, the measured value can be cor
-
rected by the set value.
E E -5 - 5 K 0.0 K 1 K
T-Flow Day Only if [HC Function] parameter = 1
Setting of the target T-HS for the heating circuit during the heating time in operating mode: "Au-
tomatic 1", "Automatic 2", "Heating".
E E 20 - 90 °C 40 °C 1 °C
T-Flow Night Only if [HC Function] parameter = 1
Setting the flow target temperature for the heating circuit during the setback time for the oper-
ating mode: "Automatic 1", "Automatic 2", "Reducing".
E E 10 - 90 °C 10 °C 1 °C
Max T-Flow Setting limits the T-HS (measured at t
v2
) with active heating support function.
The determined target T-HS of the heating circuit is limited to the maximum value set here.
If an optionally connected mixed heating circuit requests a higher temperature of the heat gen-
erator, this is taken into account. Thus, the internal circulation pump of the heat generator al-
ways runs if it is switched on. If the direct heating circuit supplies the floor heating, a
mechanical temperature limiter must be installed to prevent any overheating of the screed.
N E 20 - 90 °C 80 °C 1 °C
Min T-Flow The determined flow target temperature of the heating circuit is limited to the minimum value
set here.
N E 10 - 90 °C 10 °C 1 °C
