This function is used in the controlled drying of floors. It adjusts the flow temperature to a tempera-
ture profile. Drying is performed by floor heating via the heating circuit with a mixing valve or with a
pump.
– Floor curing function:
• Off: The function is deactivated.
• Heating operational (Fh): The first part of the temperature profile is automatically completed.
• Heating "ready for occupation" (Bh): The second part of the temperature profile is handled
automatically.
• Heating "ready for occupation"/Heating operational: The full temperature profile (1
nd
2 part) is performed automatically.
• Manual: No temperature profile is performed, but the control is performed according to the
"manual controlled drying setpoint". The function is automatically terminated after 25 days.
Important
• The standards and directions of the building contractor must be followed.
• This function will not work properly unless the installation has been adequately made (hy-
draulic, electricity, settings). Otherwise, floor to be dried may be damaged.
• The function may be prematurely interrupted by setting it to Off.
• The maximum flow temperature limitation remains active.
X: Starting day
Comply with the standards and instructions of the manufacturer of the building.
A good performance of this function is only possible with an installation correctly implemented
(hydraulic, electricity and adjustments).
This function can be stopped by anticipation when setting the adjustment on "Off".
– Floor curing setpoint manually:
The flow temperature setpoint for the "Manual" controlled floor drying function can be adjusted
respectively for each heating circuit.
– Floor curing day current:
Displays the current flow temperature setpoint for the controlled floor drying function.
