Units with two control circuit boards

Only the following types: DF S-250-E, M-250-E.
These units have two control circuit boards that each control
a part of the unit. The control circuit board on the connec-
tion side has been configured as master on delivery.
You can connect one or more of these units to a single con-
trol panel in combination with other units. The following
applies in this regard:
• A unit with two control circuit boards counts as two units.
• A unit with two control circuit boards is always the mas-
ter unit. Units with a single control circuit board must be
configured as normal units.
• If several units have two control circuit boards, then one of
these units is configured as the master unit. All control cir-
cuit boards in all other units must be configured as normal
units.
• The control panel and the external control components
must always be connected to the master unit.
2.7.2 Control panel settings
Optional
Several dip switches are located inside the control panel.
These allow the control panel to be configured.
