TAg Outside temperature mixed
When only a small heating output is required to cover demand, the
reduced room setpoint can be increased in the case of cold outside
temperatures. This increase is subject to outside temperature. The lower
the outside temperature, the higher the reduced room temperature
setpoint will be increased. The start and end of the increase can be
selected. Between these two points there is a linear increase of the
"reduced setpoint" up to the "comfort setpoint".
Continuous pump operation (809, 1109, 1409)
This function is used to suppress the pump switching off during the quick
reduction and when the room setpoint is reached (room thermostat, room
sensor or room model).
No: the heating circuit pump /boiler pump can be switched off by quick
reduction or reaching the room set point.
Yes: the heating circuit pump/boiler pump remains switched on even
during the quick reduction and after the room setpoint has been
reached.
Overtemp prot pump circuit (820, 1120, 1420)
This function prevents overheating of the pump heating circuit by switching
the pump on and off, if the flow temperature is higher than the flow
temperature required according to the heating curve (e.g. in case of higher
requests from other consumers).
Mixing valve boost (830, 1130, 1430)
The heat request of the mixed heating circuit to the heat source is raised
above the value set here. This boost is intended to correct temperature
fluctuations to be able to be compensated with the mixer controller.
Actuator running time (834, 941, 1134)
Setting the actuator running time of the mixing valve used.
For mixing circuits, a kick-start of the mixer drive is carried out after a
pump kick-start (pump is OFF). In this case, the mixer is controlled in
direction OPEN and CLOSED.
The time of activation in direction OPEN corresponds to the drive running
time.
Floor curing function (850, 1150, 1450)
X Start day
Fh Functional heating
Ch Curing heating
The floor curing function serves controlled drying out of screed floors
Off: The function is switched off.
Functional heating: Part 1 of the temperature profile is run automatically.
Curing heating: Part 2 of the temperature profile is run automatically.
Functional/curing heating: The whole temperature profile is run
automatically.
Manually: Manual control to the screed setpoint.
Caution
Observe the requirements and standards issued by the screed
manufacturer.
A correct function is only possible with a correctly installed heating system
(hydraulic, electrical systems and settings).
Deviations can result in damage to the screed.
The screed function can be stopped prematurely by setting 0=OFF.
