5.2.3 Level "HC Configuration"
Max Pressuredrop
Defines the maximum acceptable pressure drop in the heating system.
Pressure monitor function (only if the pressure sensor is activated, [Pressure Config] = On,
see tab. 5-1): If the measured value exceeds the value set in the [Set Point Pressure] param-
eter by more than the set amount, a warning message is generated.

Relay Test
Manual actuation of individual relays for test purposes. After confirmation of this parameter
using the rotary switch, the list of the relays 1 - 9 is displayed with selection boxes. For selec-
tion and confirmation of a relay using the rotary switch, a tick is set in the selection box and
the respective relay is activated. Multiple selections can be made
Relay 1: Output J1 (internal heating circulation pump),
output pump
Relay 2: Output J14 (circulation pump - ),
mixer "open"
Relay 3: Contact A to output J2 (change-over valve 3UVB1),
mixer "closed"
Relay 4: Contact B to output J2 (change-over valve 3UVB1)
Relay 5: Output J12, change-over valve 3UV DHW, "closed"
Relay 6: Output J12, change-over valve 3UV DHW, "open"
Relay 7: Port J3 (potential-free relay: NO contact B-B1) - AUX
Relay 8: Port J3 (potential-free relay: Change-over contact A-A1/A-A2) - AUX
Relay 9: Output J10 (power supply A1P)

mode

T-Frost Protect
Off: No frost protection of the heating circuit
Otherwise: If the outside temperature falls below the programmed value, the system
switches into the frost protection mode (switches the pumps on). The function ceases
once the outside temperature has risen to the set value +1 K.

Screed
Function for screed drying
Off: Deactivated
On: The flow temperature is regulated according to the set screed programme. The day
on which the screed function is activated does not count towards the running time of the
screed programme. The first day starts as the day changes on the first day at 00:00. On
the day of activation we heat for the remaining time at the inflow temperature for the first
day’s program (see chapter 3.6.13).

Screed Program
Setting the procedural program for screed heating. An individual inflow temperature can
be set for each day for a maximum period of 28 days. The end of the screed programme
is defined by the 1st. Day at target value setting "- - - -" (see chapter 3.6.13).

Heating
T-Outside lim day
Setting the automatic summer shutdown of the heating system. If the outside tempera-
ture measured and averaged out by the controller exceeds the set value by 1 K, the
heating circuit is switched off. The heating is released again if the outdoor temperature
falls below the set heat curve.

Room Influence
Only if the room station
is connected and assigned to the heating circuit.
Setting of the impact the deviation of the room temperature measured by the
EHS157034 from the actual set value (see chapters 3.4.3 and 3.4.4) has on the flow
temperature.
Off: Exclusively weather-controlled flow temperature regulation
0: Purely weather-controlled flow temperature regulation, but internal heat recirculation
pump continues to run until the next heating cycle following a heat demand during the
setback time.
1-20: Causes a correction of the set flow temperature (parallel shift of the heat curve)
by the set factor.
For example: If the measured temperature is 2 K below the set value, the set flow tem-
perature is raised 2-times the set value.

T-Room Adj
Only if the room station

Individual adaptation of the room temperature relevant for control.
Should a systematic deviation of the room temperature as measured by the EHS157034
from the actual temperature in the living area of this room be detected, the measured
value can be corrected by the set value.
