Frost pr. T (frost protection temp.)

Set the desired flow temperature at temperature sensor S3 to protect the
system against frost (at heating cut-out, total stop etc.).
When the temperature at S3 gets lower than the setting, the motorized
control valve opens gradually.
See Appendix “Parameter ID overview”
The frost protection temperature can also be set in your favorite
display when the mode selector is in frost protection mode.

Input selected for external override.
If S1... S6 is chosen as override input, the override switch must have
gold-plated contacts.
If S7 ... S10 is chosen as override input, the override switch can be a
standard contact.
See the drawing for a connection example of an override switch
to input S9.
The two drawings (override to comfort mode and override to
saving mode) show the functionality.
Choose only an unused input for override. If an already used input is
applied for override, the functionality of this input is also neglected.
See also ‘Ext. mode’.
