The Start-up option is used for switching on the loading pump with a delay to a
demand. If the adjusted minimum temperature at the allocated sensor is exceeded
or the adjusted start-up time has elapsed, the corresponding relay switches on.
The Overrun option is used for switching off the loading pump with a delay to a
demand. If the temperature falls below the adjusted remaining boiler temperature
or the adjusted overrun time has elapsed, the corresponding relay switches off.
Valve
Valves and parallel relays can use the shared relays Valve 1 and Valve 2. These
shared relays are energised individually or along with a reference relay (e. g. loading
pump).
6.2 Heating circuits
The controller has 1 mixed and 1 unmixed weather-compensated heating circuit
and is able to control up to 5 further mixed heating circuits by means of extension
modules.
If one or more extension modules are connected, they have to be registered
with the controller. Only registered modules are available in the heating circuit
selection (see page 46).
If New HC… is selected for the first time, the first heating circuit is allocated to
the controller. The operating mode of the first heating circuit also applies to all
further heating circuits, if they are linked.
In the heating circuit menu, relays for the heating circuit pump and the heating
circuit mixer can be selected. Change the factory setting only if required.
3 free relays are required for a mixed heating circuit. If less than 3 free relays are
available on the controller or module, a static (unmixed) heating circuit can be
allocated.
If the measured flow temperature deviates from the set flow temperature, the
mixer will be activated in order to adjust the flow temperature correspondingly.
The mixer runtime can be adjusted with the parameter Interval.
The heating system Constant aims to keep the set flow temperature at a con-
stant value which can be adjusted by means of the parameter Set temperature.
An outdoor temperature sensor cannot be allocated.
If the heating system Curve is selected, the controller calculates a set flow tem-
perature by means of the outdoor temperature and the selected heating curve.
In both cases, the dial setting of the remote control and the controller day correc-
tion or night correction are added.
