Diverting valve
Additional parameters

Building Technologies Division
The diverting valve is driven to the position demanded by the current heat request:
DHW or space heating (heating circuit). If there is no request for heat, the diverting
valve assumes its basic position. This can be selected via parameter Basic position
DHW div valve (5734).
The following choices are available:

Last request (0): Diverting valve maintains the position resulting from the last
heat request

Heating (1): Diverting valve is driven to the position for space heating

DHW (2): Diverting valve is driven to the position for DHW heating
During the time the diverting valve is driven to the other position, it may be necessary to
temporarily deactivate the pump. Using parameter Pump off change div valve (5732),
the period of time the pump shall be deactivated can be set. Parameter Delay pump off
(5733) can be used to parameterize a temporal offset of pump shutdown against the
control of the diverting valve.
