Activating the function
If setting 1), 2) or 3) is made via the setting parameter, the respective floor curing func-
tion will be carried out.
The floor curing function can be activated only with applications using a mixing heating
circuit.
With the pump heating circuit application, this function cannot be activated.
4.213.3
Function
When the floor curing function is activated, parameter "Maximum limitation of flow tem-
perature Tvmax" will automatically be set to 55 °C. If required, this value can also be
adjusted manually. This value will then be used as the maximum value for the floor
curing function and will be maintained when floor curing is terminated.
The starting day, that is, the period of time from activation until midnight, is not consid-
ered day 1 of the selected temperature profile. The starting day is called day 0 and
adopts the flow temperature value of day 1.
The flow temperature changes dictated by the temperature profile always take place at
midnight.
When the floor curing function is activated, the mixing valve ensures that the flow tem-
perature dictated by the temperature profile will be maintained. This means that protec-
tive boiler start-up or d.h.w. heating with absolute or shifting priority have no impact on
the floor curing function.
In the event of a power failure, the function will be resumed where operation was
stopped.
Manual operation is given priority over the floor curing function. When manual operation
is activated, the mixing valve will be de-energized (relay contacts open). As a result, the
floor curing function does not affect the mixing valve.
4.213.4
Display
The flashing heating circuit operating mode button indicates the activated function.
4.213.5
Aborting the function
The following events cause abortion of the floor curing function:
−
The selected floor curing function is completed
−
Setting parameter "Floor curing function" is set inactive
