frost protection
Off/On Setting that determines whether the frost
protection function is to be based on the
outside temperature.
When frost protection is On, the pump is
switched on when the set temperature is reached
and the mixer controls the flow temperature with
reference to the value set under the menu item
Set flow temperature with frost protection.
Frost protection below
Outside Temperature
-20...5...30 °C Setting that determines the outside
temperature from which frost protection is to
be activated.
Room temperature-
dependent frost protection
Off/On Setting that determines whether the frost
protection is to the based on the room
temperature.
A room thermostat must be installed for this
function.
Frost protection below Room
Temperature
1...5...30 °C Setting that specifies the room temperature
from which frost protection is to be activated.
Set flow temperature with
frost protection
3...10...100 °C Setting that specifies the minimum flow
temperature to be reached when the frost
protection function is active.

Explanation Note
Screed drying Off/On Switching the drying program on/off. Chapter 12.4, page 36
End automatically Off/On Setting that determines whether the drying process
should end automatically.
Pause Off/On Setting that determines whether the drying process
should be interrupted.
Continue Off/On Setting that determines whether the drying process
should be automatically resumed following the
interruption.
Waiting time 0...50 days Screed drying program starts once the set waiting time
has elapsed.
Hold start phase 0...3...30 days Time delay between the start of the start phase and the
next phase
Start temperature 20...25...55 °C Flow temperature during the start phase
Ramp-up 0...1...10 days Setting that determines the daily cycle for increasing the
temperature in order to dry out the screed.
Ramp-up by 1...30 K Setting that specifies the increments in which the
temperature should increase to dry out the cement
Hold maximum temperature 1...7...99 days Setting the period of time for which the maximum
temperature should be maintained in order to dry out
the screed.
Maximum temperature 20...45...55 °C Setting the maximum temperature for screed drying
Setting back 0...1...10 days Setting that specifies the daily cycle in which the
temperature should drop to dry out the screed.
With the setting None, screed drying ends
at the end of the maximum holding time.
Setting back by 1...5...35 K Setting that specifies the increments in which the
temperature should decrease to dry out the screed.
Hold minimum temperature 0...1...30 days Setting that specifies the period of time for which the
minimum temperature should be maintained in order to
dry out the screed.
Minimum temperature 20...25...55 °C Setting that specifies the minimum temperature for
drying out the screed
Maximum pause time 2...12...24 h Setting the time that must elapse (e.g. in the event of a
power failure) in order still to be able to continue the
drying process successfully.
