Set Extra Heat Curve With Shunt - IVT Greenline HT Plus C Assembly, Commissioning And Maintenance Manual

Set extra heat curve with shunt

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.
