INDOOR THERMOSTAT UNIT
(
ROOM SENSOR)
If an indoor thermostat unit is connected, the target room
temperature is calculated from the preset day and night room
temperatures, the room influence factor and the current measured
room temperature.

EATING SYSTEMS FOR THE
HEATING CIRCUITS
In the paramater group “8 - Hydraulic system”, the corresponding
heating system is configured for each of the various heating circuits.
There is a choice of five heating systems:
• None
– This is selected whenever a heating circuit is not needed. All
submenus for this heating circuit are then disabled.
• Radiators
– If this heating system is selected, the corresponding
parameters are loaded and a characteristic heating curve
allocated.
• Floor heating
– If this heating system is selected, the corresponding
parameters are calculated for a flatter characteristic heating
curve and a lower laying temperature. With this heating
system, you also have the option of activating a screed drying
programme.
• Constant
– This system operates independently from the outdoor
temperature and maintains a constant water temperature as it
leaves the boiler. This system is suitable, for example, for
controlling the heating of a swimming pool. An indoor
thermostat unit cannot be integrated with this heating system.
• Uncontrolled
– In an uncontrolled heating system, only the enable
temperature and the time programme are taken into account.
This heating system operates without a heating circuit mixer. If
combined with an indoor thermostat unit, the pump switches
off after the desired room temperature is reached.
