ECL Comfort 210 / 310, application A214 / A314
6.8.5 Energy meter (heat-meter) and M-bus, general information
ECL 310 only
When using the Application Key in the ECL Comfort 310 / 310B, up
to 5 energy meters (heat-meters) can be connected to the M-bus
connections.
Connection of energy meter can:
•
limit the flow
•
limit the power
•
transfer energy meter data to the ECL Portal, via Ethernet, and /
or a SCADA system, via Modbus.
Many applications with control of heating, DHW or cooling circuit
have the possibility to react on energy meter data.
To verify if actual application key can be set to react on energy
meter data:
See Circuit > MENU > Settings > Flow / power.
The ECL Comfort 310 can always be used for monitoring purpose
of up to 5 energy meters.
The ECL Comfort 310 acts as an M-bus master and must be set to
communicate with connected energy meter(s).
See MENU > Common controller > System > M-bus config.
Technical info:
•
The M-bus data are based on standard EN-1434.
•
Danfoss recommends AC supplied energy meters in order to
avoid battery draining.
Energy meter data acquisition from ECL Portal is possible without
setting up the M-bus configuration.

300
The communication speed between ECL Comfort 310 and the connected
energy meter(s).
Typically, 300 or 2400 baud is used.
If ECL Comfort 310 is connected to the ECL Portal, a baud rate of 2400
is recommendable, provided the energy meter allows this.
