Part 2: Overview of display values and settings
30
Mixer Open
(open mixer dynamic)
Speed setting at which the mixer opens when a control
difference occurs. The control difference at which the
mixer opens without interruption is entered in Kelvin.
!
Small values cause the mixer to adjust quickly and
can lead to oscillation.
Mixer Close
(close mixer dynamic)
Speed setting at which the mixer closes when a control
difference occurs. The control difference at which the
mixer closes without interruption is entered in Kelvin.
!
Small values cause the mixer to adjust quickly and
can lead to oscillation.
Max T-Flow
(max. flow temperature)
The measured temperature setting for the heating circuit
flow is limited to the maximum flow temperature setting
(overheating protection).
E
The heating circuit pump of the direct heating circuit is
not switched off until the boiler temperature exceeds
the set maximum flow temperature by 8K. The
heating circuit pump is already switched on again
when the boiler temperature drops below the
temperature [maximum flow tempe 5K].
Min T-Flow
(min. flow temperature)
The measured temperature setting of the heating circuit
flow is increased to the minimum flow temperature setting
(e.g. with air heating).
T-Flow cooling
(only in installation cooling mode)
In the Cooling operating mode, this temperature is
adjusted via the mixer in the heating circuit flow.
OFF = Heating circuit is not cooled (Mixer Close, Pump
Off)
CLOSE = Mixer as bypass valve (Mixer Close, Pump On)
T-Frost protect
(frost protection temperature)
If the outside temperature drops below the programmed
value, the system switches to frost protection mode
(pumps are switched on).
"----" Frost protection mode is deactivated!
Outdoor delay
(outside temperature delay)
The selected outside temperature delay must be matched
to the type of construction of the building. In the case of
heavy structures (thick walls), a long delay must be
selected since a change in outside temperature affects
the room temperature later accordingly. With light
structures (walls have no storage effect) the delay should
be set (0 hrs.).
Slope Offset
(heating slope distance)
The boiler temperature that is required for a mixer circuit
is calculated by adding the calculated temperature setting
for the heating circuit flow to the heating curve distance.
The heating curve distance compensates for sensor
tolerances and heat loss up to the mixing valve.
B-Heat Sink
(circuit enable)
On => The heating circuit can be used by higher-order
functions (e.g. emergency cooling function of a heat
generator to protect from overheating; heat removal
during service mode) as a heat sink/consumer. The
heating circuit is heated at the maximum flow
temperature setting for the duration of the function.
