MI 04 Screed drying If an under oor heating system is started for the  rst time in new

buildings, the set  ow temperature may, as an option, be controlled

independent of the outside temperature either to a constant value or

to control the set  ow temperature in accordance with an automatic

screed drying program.

If this function has been enabled (setting 1 or 2), it can be terminated

by resetting parameter MI 04 to 0.

MI 04 = 0 without function

MI 04 = 1 constant temperature mixer circuit

The mixer circuit is heated to the set  ow temperature. The set

 ow temperature is permanently set to the temperature selected

in parameter MI 01.

MI 04 = 2 screed drying function

For the  rst two days, the set  ow temperature will remain constant

at 25 °C. It will then be automatically raised every day (at 0:00 h)

by 5 °C up to the maximum mixer circuit temperature (MI 02).

That temperature will then be held for two days. Subsequently,

the  ow temperature is automatically reduced again in 5 °C steps

per day to 25 °C. The program sequence is terminated after a

further two days.

NB:

Agree the time sequence and the maximum  ow temperature with

the screed contractor, otherwise the screed may be damaged,

particularly through cracking.

The screed drying program continues after a power failure. The

remaining time in days is displayed at the BM.
