T-Flow CH adj
Only if parameter [Interlink fct] = On:
When the RT switching contact cooling
is closed, the target feed temperature is increased
by the set value (see tab. 6-1, parameter [Interlink fct]). Request e.g. through HP convector.

T-Flow Cooling adj
Only if parameter [Interlink fct] = On:

Min Pressure
Defines the minimum water pressure.
Pressure monitor function (only with activated pressure sensor, [Pressure Config]=On, see
tab. 6-1): if the measured value falls below the set value, the ROTEX HPSU monobloc compact
is shut off and an error message is generated.

Set Point Pressure
Defines the target water pressure.
Pressure monitoring function (only with activated pressure sensor, [Pressure Config]=On, see
tab. 6-1): If the measured value undercuts the set value by more than the value set in the [Max
Pressuredrop] parameter, a warning message is generated.

Max Pressuredrop
Defines the maximum acceptable pressure loss in the heating system.

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)
Relay A: output J17 (pin 3) - relay K2 (RTX-EHS) output XBUH1 T2
Relay B: output J17 (pin 2) - relay K3 (RTX-EHS) output XBUH1 T1
Relay C: output J17 (pin 4) - relay K1 (RTX-EHS) output XBUH1 T3

T-Frost Protect
Off: No frost protection of the heating circuit
Otherwise: If the outside temperature drops below the set value, the system switches to
frost protection operation (the pumps are switched on). The function is ended if the out-
side temperature rises above the set value +1 K.

Screed
Function for screed drying
Off: Deactivated
On: the target feed temperature is regulated according to the set screed program. The
day on which the screed function is activated is not included in the running time of the
screed program. The first day starts when the day changes at 00:00 am. On the day of
activation, heating is carried out for the remaining time with the target feed temperature
of the first day's program (see chap. 3.6.13).

Screed Program
Setting of the sequence program of the screed heating. A separate target feed temper-
