EA1 extension

Part no. 7452091
Function extension inside enclosure for wall mounting.
Using the inputs and outputs allows up to 5 functions to be
achieved:
1 switching output (floating changeover contact)
■ Central fault message output (only with Vitotronic 100, type HC1B
and Vitotronic 200, type HO1B)
■ Switching the feed pump to a substation
■ Switching the DHW circulation pump (only with the Vitotronic 200,
type HO1B)
1 analogue input (0 to 10 V)
■ Specifying the set boiler water temperature
3 digital inputs
■ External operating program changeover for 1 to 3 heating circuits
(only with Vitotronic 200, type HO1B, and Vitotronic 300-K,
type MW2B)
■ External blocking
■ External blocking with central fault message
■ Minimum boiler water temperature demand
■ Fault messages
■ Short term operation DHW circulation pump (only with
Vitotronic 200, type HO1B, and Vitotronic 300-K, type MW2B)
■ Signalling reduced operation for one heating circuit (only for
Vitotronic 300-K, type MW2B)
Power supply for DHW circulation pump
DHW circulation pumps with their own internal control unit must be
connected to a separate power supply. Mains connection via the
Vitotronic control unit or Vitotronic accessories is not permissible.

Vitocom 300, type LAN3
Part no: see current pricelist
For remote monitoring, telecontrol and remote setting of heating sys-
tems via IP networks (LAN).
As an internet data transfer establishes a permanent connection
("always online"), access to the heating system is particularly fast.
For heating systems with one or more heat sources, with or without
heating circuits downstream
For system operation with Vitodata 300
Functions when operating with Vitodata 300
For all heating circuits in a heating system:
■ Remote monitoring:
– Forwarding messages via SMS to mobile phone/smartphone, via
email to end devices with email client functionality or via fax to
fax machines
– Monitoring additional devices via the inputs and outputs of the
Vitocom 300
■ Telecontrol:
– Selecting operating programs, set values, time programs and
heating curves
– Recording trends via datalogger
– Recording energy consumption through integration of M BUS
heat meters
■ Remote setup:
– Configuring Vitocom 300 parameters
– Remote setup of Vitotronic control parameters via coding

charges have to be taken into account for Vitodata 300.
■ For more information, see www.vitodata.info.
Configuration
■ In the case of dynamic IP addressing (DHCP), the IP configuration
of the Vitocom 300 occurs automatically.
No adjustments have to be made on the DSL router.
■ Observe the network settings of the DSL router.
■ The outputs and inputs of the Vitocom 300 and EM301 extension
module are configured using the Vitodata 300 user interface.
■ The Vitocom 300 is connected to the Vitotronic control unit via
LON. The Vitocom 300 does not need to be configured for the
LON.
Fault messages
Fault messages are reported to the Vitodata server. These mes-
sages are transmitted via the following communication services from
the Vitodata server to the configured recipients:
■ Fax
■ SMS to mobile phones
■ Email to PC/laptop
