▶ Before carrying out electrical work:
– Isolate all poles of the mains voltage and secure against
reconnection.
– Using suitable means, test the power supply is
disconnected.
▶The product requires different voltages.
Do not connect the extra-low voltage side to the mains
voltage or vice versa.
▶ Also observe connection diagrams of other system
components.
Handover to the end user
When handing over the heating system, explain the operating
conditions to the user.
▶ Explain how to operate the heating system, with particular
emphasis on all safety-related actions.
▶ Explain that conversions or maintenance must only be
carried out by a suitably qualified engineer.
▶ Point out the need for inspections and maintenance for
safe and environmentally friendly operation.
▶ The installation and operating instructions must be given to
the end user for safekeeping.
Damage caused by frost
The system can freeze if it is switched off:
▶ Observe the notices regarding frost protection.
▶ Due to the additional functions, e.g. DHW heating or anti-
seizing protection, the system should always be left on.
▶ Correct any faults immediately.
2 Product details
• The module is used to control the activation of a swimming
pool in conjunction with a heat pump with an EMS 2/EMS
plus interface. The heating circuit for the swimming pool is
heated directly by the heat pump via a diverter valve, and it
is installed before a buffer cylinder or a hydraulic
separator.
• The module is used to determine the swimming pool
temperature and activate a mixer as required by the heat
pump.
• Anti-seizing function: the connected mixing valve actuator
is monitored and run automatically for a short period after
24 hours of downtime. This prevents the mixer from
seizing up.
A maximum of one MP 100 is permitted in a system,
irrespective of the number of other BUS nodes.
