Summer mode
The Mode channel adjustment determines how the heating circuit is set to sum-
mer mode:
Summer off: The summer mode becomes active when the outdoor temperature
exceeds the adjusted summer temperature TSummer.
Ext. switch: A switch is connected to a selected sensor input. If the switch is
operated, the heating circuit is set to summer mode regardless of the outdoor
temperature.
Both: As long as the switch is not operated, summer mode control works as
described for Summer off. If the switch is operated, the heating circuit is set to
summer mode regardless of the outdoor temperature.
Summer temperature
If Summer off or Both has been selected in the Mode channel, the summer
temperature TSummer can be adjusted. If the outdoor temperature exceeds the
value adjusted in TSummer, the heating circuit pump is switched off.
10.2 Heating circuits (with EM Extension Modules only)
The controller is able to control 2 external, weather-compensated 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.
In the menu appearing when new HC… is selected, it is possible to choose be-
tween registered modules.
Extension modules can be registered in the In-/Outputs / Modules menu.
If an external heating circuit has been selected, a new menu opens. In this menu, all
sensors and relays required for the heating circuit can be allocated, and all adjust-
ments can be made.
Note:
Only relays and sensors of the modules registered are available!
The controller calculates the set fl ow temperature for each heating circuit by
means of the outdoor temperature and the selected heating curve. If the measured
fl ow temperature deviates from the set fl ow temperature, the mixer is activated in
order to adjust the fl ow temperature correspondingly.
If the outdoor temperature falls below the point where the calculated set fl ow
temperature would exceed the maximum fl ow temperature, the maximum fl ow
temperature is treated as the set temperature for as long as the condition remains.
If the outdoor temperature sensor is defective, an error message will be indicated.
For the duration of this condition, the maximum fl ow temperature -5 K is assumed
as set fl ow temperature.
With the timer, the day / night operation can be adjusted. During day phases, the set
fl ow temperature is increased by the adjusted Day correction value, during night
phases it is decreased by the Night correction value (night setback).
