11.3. Antifreezing (FRE)
When the antifreezing function of the thermostat is activated, the thermostat
will switch on its output, regardless of any other setting, when the temperature
measured by the thermostat goes below 5 °C. When the temperature reaches
7 °C, normal operation of the output is restored (according to the set tempera-
ture).
11.4. Memorizing ON/OFF status in case of a power failture (PON)
By means of the Memorizing Settings function of the thermostat you can select
the mode in which the thermostat continues to operate:
• 00/OFF: the thermostat turns o and remains turned o until this mode is
altered, regardless whether the thermostat was on or o before the power
failure.
• 01/ON: the thermostat returns to the same state in which it was before the
power failure (default setting).
11.5. Changing between heating or cooling mode (FUN)
You can easily switch between heating (00; factory default) and cooling
(01) modes.
The connection points NO and COM of the thermostat’s output relay close at a
temperatures below the set temperature in heating mode and at tempera-
tures above the set temperature in cooling mode (taking the set switching
sensitivity into account).
