• Pump seizure protection function:
– The connected pump is monitored and ran for a short period after
24 hours of downtime. This prevents the pump from seizing.
A maximum of three modules per system are permissible, irrespective of
the number of other BUS subscribers:
• a maximum of two modules for a total of six heating circuits without
electronic mixing valves
• a maximum of one module for two additional heating circuits without
electronic mixing valves and one cylinder charging circuit
As delivered, the code switch is set to
Y
. The module will therefore
operate the system as a mid-position (Y-plan). S (S-plan) or other
configurations can be selected when necessary.
2.1
CORRECT USE
The module communicates via an EMS-plus interface with other EMS-
plus-enabled BUS subscribers such as Greenstar boilers.
▶ Only use the appliance for its intended purpose.
▶ Observe all country-specific regulations and standards during
installation and operation.
