Installation Guide ECL Comfort 210 / 310, application A237 / A337
Application A237.1 (used in ECL Comfort 210) / A337.1 (used in
ECL Comfort 310) in general:
A connected flow or energy meter (in ECL Comfort 210 it is based
on pulse signals and in ECL Comfort 310 based on M-bus signal)
can limit the flow or energy to a set maximum but also in relation
to the outdoor temperature.
Unused input can, by means of an override switch, be used to
override the schedule to a fixed 'Comfort' or 'Saving' mode.
Modbus communication to a SCADA system can be established. In
ECL Comfort 310 the M-bus data can furthermore be transferred
to the Modbus communication.
Alarm relay (in ECL Comfort 210 it is R4 and in ECL Comfort 310
R6) can be activated if the actual flow temperature differs from
the desired flow temperature.
Valid for ECL Comfort 310 only: A 0 -10 volt signal can be applied to
the input S10 in order to override and control the flow temperature.
Depending on system type, it is recommended to change some
factory settings individually in order to optimize the functionality.
These setting changes, if required, are listed below the system
types in the section 'Identifying the system type'.
Valid for ECL 310 only: A room temperature sensor can be
connected in order to give feedback about the room temperature.
