unit can be switched off and the system can be filled
completely.

Screed drying

When activating screed drying, observe the informa-
tion provided by the screed manufacturer.
When screed drying is activated, the heating circuit
pump for the heating circuit with mixer starts and the
flow temperature is maintained in accordance with the
selected profile. On completion (30 days), the heating
circuit with mixer is controlled automatically according
to the set parameters.
Note
Temperature profile 6 ends after 21 days
