– Floor curing day completed:
Displays the current day of the controlled floor drying function.
Important
After a power outage, the installation resumes the controlled drying function as it was when the
outage occurred.
• Operating mode changeover
HC1
900
In case of an external changeover via input H2 (on the extension module only) the operating mode
to which the changeover will be performed must be previously defined.
• Heating circuit frost protection
The heating circuit frost protection is continuously activated (protection mode ) and is not ad-
justable.
• Heating circuit frost protection in heating mode: If the flow temperature is below 5°C, the con-
troller initiates the production of heat and starts the heating pump, regardless of the current heat-
ing mode. If the flow temperature rises again above 7°C, the controller waits another 5 minutes,
and then stops the production of heat and the heating pumps.
• Heating circuit frost protection in cooling mode: Refer to cooling mode.
