Collector frost protection FROST
This function is disabled ex works and is only necessary for solar power systems that run
without antifreeze: In the south, the energy from the solar cylinder suffices to keep the
collector at a minimum temperature for the few hours below freezing. At
min of 2°C on
the collector sensor, the settings in the chart release the solar pump and block it again at
min
 of 4°C.

Setting of the outputs to be blocked when the switch-on threshold is fallen short
of. If a control output is allocated to the output, then the analog stage 100 is
additionally output at this control output. (ex works

NOTICE: If the frost protection function is activated and an error occurs at the set
collector sensor (short circuit, interruption), the set output is switched on at the
top of every hour for 2 minutes.
The frost protection function is available twice and is indicated by the index (1
or 2) in the lower display line.
If the drain-back function is activated the frost protection function is blocked
(with the exception of program 4).
