Description
Heating circuits 1-4*
For more settings for the individual heating circuits, see below this table.
Heating curve
Linear
The heating circuit control of the two heating circuits is based on a linear
calculation.
Curve set
The heating circuit control of the two heating circuits is based on a
heating curve. Details can be found in the section
Selecting the heating
curve from a set of curves
starting on page 29.
Multi-room control
If you use more than one room sensor, you can implement multi-room
control with this function. Comfort will be increased and energy
consumption will be optimised.
You can choose between the following room analysis methods:
-
Min
: The lowest temperature of all active sensors is decisive
-
Max
: The highest temperature of all active sensors is decisive
-
Average
: The average temperature of all active sensors is decisive
-
Switch
: The heating circuit will be switched off when the room
setpoint temperature is exceeded at all active sensors
Room influence
Here you can define the influencing factor of the room sensors.
You can chooce between
low, medium and high
and the supply line
temperature correction will be calculated accordingly.
OT smoothing
Here you can set a value in hours for the smoothing of the outdoor
tempertaure according to the building's insulation. This makes
allowance for the building's inertia.
Examples:
Poorly insulated building (e.g. an old building with no insulation): 4h. A
very well insulated building (e.g. a new building, a KfW efficiency house
type 70, 55, 40): 24h
dt On heat
If the temperature at the middle of the storage tank lies below the
calculated supply line setpoint value plus "dt On heat", the reheating by
boiler will be switched on.
If there are two heating circuits, the higher supply line setpoint value will
be considered.
dt Off heat
If the temperature at the middle of the storage tank lies above the
calculated supply line setpoint value plus "dt On heat" plus "dt Off heat",
the reheating will be switched off.
Request
Switch the "Request" function on or off
Here you can deactivate the boiler function. In this case the multi-
function controller will become available on R0.
Min runtime
This parameter is used to set a minimum time during which the request
will remain active.
