The MB LAN 2 can be used to control and monitor the heating system via
1
a mobile phone.
To be able to use the MB LAN 2, the following prerequisites must be met:
• Internet access is available.
• The RJ45 output of the router is available.
• The corresponding app is installed on the mobile phone.
Additional costs may be incurred when using the Internet access for the
MB LAN 2.
▶ Connect the MB LAN 2 to the following connections:
– Power supply for MB LAN 2 12 V
– EMS
(Chapter 12.2 on page 33 [3 and 6])
If an accessory is already connected at the EMS connection:
▶ Connect the MB LAN 2 to the EMS connection parallel to the
accessory which has already been installed( Chapter 6.7.1
on page 19).

External inputs

NOTICE
Damage due to incorrect connection!
Connections intended for a different voltage or current can damage
electrical components.
▶ Only perform connections to the heat pump's external inputs which
are designed for 5 V and 1 mA.
▶ If an intermediate relay is required, use only relays with gold-plated
terminals.
The external inputs can be used for the remote control of certain
functions in the user interface.
Those functions which are activated by the external inputs are described
in the operating manual for the user interface.
The external inputs are connected either to a circuit breaker for manual
activation or a control device with a relay output for 5 V.
