Up to two Remote Control Units, ECA 30 / 31 can be connected to
one ECL controller in order to control the ECL controller remotely.
Exercise of circulation pumps and control valve in periods without

485 bus in order to utilize common outdoor temperature signal,
time and date signals. The ECL controllers in the ECL 485 system
can work in master - slave system.

override the schedule to a fixed 'Comfort' or 'Saving' mode.
