Set extra heat curve with mixing valve
If you have fl oor heating combined with radiators you should set an extra
heat curve with mixing valve. The mixing valve is a valve that lets water
through in different amounts. It prevents the fl oor from becoming too hot
and destroying the fl ooring. The menu is only displayed when there is an
extra fl ow sensor, T4 (GT4), on the heat pump. You set the extra heat curve
using two menus:
Mix. valve incr/decr
and
Mix. valve fi ne-tune
.
Increase or decrease the mixing valve
1. Press the Heat button until Access = CUSTOMER2 is displayed.
2. Press the Heat button.
3. Turn the menu dial clockwise until you reach the menu
Mix. valve
incr/decr.
4. Press the Adjust button.
5. Turn the menu dial clockwise to choose a higher heat curve.
Turn the menu dial anti-clockwise to choose a lower heat curve.

ting circuit is heat curve 2.
