Correct Use; Standard Delivery; Specification - Bosch WORCESTER GREENSTAR WIRING CENTRE Installation, Commissioning & Servicing Instructions

• 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.
