Connecting a Frost-Protection Unit to the SBH-E
The SBH-E (since 2005) is prepared for connecting a Frost-Protection-Unit. Therefore no
electrical changes are necessary.
The software is also prepared but you must let the SBH-E know that a Frost-Protection-Unit
is attached. To do this, you change the settings (of the Dibo steering, see manual 5.2.1) At and
Ut, to 9999. Now the SBH-E is ready to use the Frost-Protection-Unit, and the internal
frostprotection is deactivated.
Connecting the Frost-Protection-Unit:

Low Pressure Water:

PAY ATTENTION: ALWAYS CHECK THE ELECTRIC PLAN ON POSSIBLE CHANGES! IT CAN BE POS-
SIBLE THAT THE ELECTRIC CONNECTIONS MENTIONED ABOVE ARE NOT BY DEFAULT.
