Parameter A8 is used to set the type of the motorized 3-way valve used to switch the direction of water flow in different
working modes. If it is set to 0, it means two directions of the valve is controlled by "with" or "without" power. If it is set
to any
value other than
0,
it means the valve takes this time to switch from one direction fully to the other
direction
.
In some special application, heating and hot water may use the same water circuit. In this way, one can set parameter A9
to 0, so unit has one water direction for both hot water and heating, and one direction for cooling only.
