9. HEATING
The emergency shutdown option is used for switching off the cooling, if the adjustable
relative humidity is exceeded. The re-energise hysteresis for this function can be adjusted. An
output can be selected which is activated during an emergency shutdown, e.g. to switch on a
fan.
When Switch is selected, an input as well as an output can be allocated to a dew point switch.
If the dew point switch detects condensation, cooling is interrupted.
If Off is selected, the Dew point option is switched off.
Backup cooling
For the backup cooling of the heating circuit, 4 modes are available:
Therm.: In this mode, the set flow temperature is compared to a store reference sensor.
Zone: In this mode, the set flow temperature is compared to 2 store reference sensors. The
switching conditions have to be fulfilled at both reference sensors.
On/Off: In this mode, the backup cooling is activated when the heating circuit pump is switched
on for cooling.
Absolute: In this mode, a switch-on and a switch-off temperature for a reference store sensor
can be adjusted.
The backup cooling is activated when the switch-on temperature at sensor 1 is exeeded and
switches off again when the switch-off temperature is reached.
In the Output submenu, the modes Standard and Demand are available. If Standard is
selected, the output can be adjusted.
If Demand is selected, a demand has to be activated and adjusted in the Heating / Shared rel.
menu first. If Adj. values is selected, the Heating / Shared rel. / Demand menu will open.
If the Holiday option is activated, the heating circuit switches into the correction mode.
