PREmax
Flow temperature maximum value
This protection function should prevent overheating of temperature sensitive parts
(e.g. floor heating pipes). The mixer control does not permit a higher flow tempera-
ture than
PREmax
.
fs = 70°C, setting range: 31 to 99°C
PREmin
Flow temperature minimum value
Even if the calculated flow temperature is below this threshold, a flow temperature
below it is nevertheless not permitted.
fs = 30°C, setting range: 0 to 69°C
Frost protection OTF / RTF
If frost protection is activated, the set flow temperature is maintained at at least
PRE
min
according to the set room temperature for frost protection
RTF
(setting in the parameter
menu), until the temperature which has triggered the frost protection function increases to 2 K
above the frost protection limit.
The frost protection is activated even if a switch-off condition would disable the pump.
The status display displays FRO and the symbol .
OTF
Outdoor temperature threshold for frost protection mode (fs = +5°C).
Setting range: -20 to +20°C
RTF
Room temperature threshold for frost protection mode (fs = +5°C).
Setting range: 0 to 30°C
