This function operates according to the
assumption that one may accept a slightly higher
indoor temperature when it is warm outside and
vice versa, providing an excellent opportunity for
conserving energy.
Support control heating/Support control cooling
Support control is normally used when room temperature
control or extract air control has been configured, to
prevent a too large offset in temperature when the unit is
“Off”.
“Support control Heating” or “Support control Cooling”
will run if support control is configured, the running
mode is "Off" (timer control OFF and not in extended
running) and if conditions call for support control.
Minimum run time is settable 0 to 720 minutes (FS= 20 minutes).
Frost protection temperature
Relevant value for the water temperature at the frost
protection sensor. Frost protection can be set to function
either on Y1, Y4 or on both. The function only supports
a single sensor.
