Temperature limit for frost protection (outside temperature
threshold value)
You can use this item to set the temperature limit for the frost protection
(threshold value for outside temperature). It is only active if either
Outside temp. or Room and outside temp. are set in the Frost
protection menu.
• If the outside temperature exceeds the frost protection temperature
limit by 1 K ( °C) and there is no heating requirement, the heating
circuit pump will be shut off.
• If the outside temperature is below the frost protection temperature
limit, the heating circuit pump will be turned on.
12.3.3 Screed drying menu
A floor plate screed drying program is set in this menu for the selected
heating circuit or the entire system. The heating system will
automatically execute the floor plate screed drying program once to dry
a new floor plate.
In case of a power outage, the user interface will automatically resume
the floor plate screed drying program, as long as the outage does not
outlast the user interface battery power or the max. outage time.
This menu is only displayed if at least one underfloor heating system
circuit is installed and set up in the system.
NOTICE: Water bearing system components can be
destroyed if the frost protection temperature limit is too
low and the outside temperature is below 0 °C for an
extended period of time!
▶ The temperature limit for frost protection (standard
setting = 5 °C) should take system prerequisites into
consideration.
▶ Do not set the frost protection temperature limit too
low. The warranty will not cover damages due to the
frost protection temperature limit set too low!
▶ Set frost protection and a frost protection
temperature limit for all heating/cooling circuits.
▶ In the Frost protection menu, set either Outside
temp. or Room and outside temp. to ensure frost
protection of the entire heating system.

The setting Room temperature will provide no frost
protection at all since e.g. pipes in walls can freeze. This
is possible even if external heat sources keep the
temperature in the reference room well above 5 °C.
When an outside temperature sensor is installed, the
entire heating system can be frost protected:
▶ Set either or Room and outside temp. in the Frost
protection menu.
NOTICE: Risk of damaging the screed!
▶ In multiple circuit systems, this function is only
available together with a heating circuit with mixing
valve.
▶ Set the floor plate screed drying program according
to the screed manufacturer instructions.
▶ Even if the drying program is ongoing, the system
should be inspected daily and the prescribed
protocol observed.
