Operating Guide
DHW circuit
A flow or energy meter can be connected to the ECL controller in
order to limit the flow or consumed power. The signal from the
flow or energy meter is a pulse signal.
When the application runs in an ECL Comfort 310 controller, the
flow / power signal can be obtained from a flow / energy meter
via the M-bus connection.
When the flow / power gets higher than the calculated limit, the
controller gradually reduces the desired flow temperature to obtain
an acceptable max. flow or power consumption.
The parameter 'Units' (ID 1x115) has a reduced setting range when
the flow / energy signal comes via M-bus.
Parameters indicated with an ID no. like "1x607" mean a universal
parameter.
x stands for circuit / parameter group.

For monitoring:
Frequency range is 0.01 - 200 Hz
For limitation:
Minimum frequency is recommended to be 1 Hz in order to have a
stable control. Furthermore, the pulses must appear regularly.
