ECA Remote controller
– Remote Control Unit (RCU):
In case of limited access to the basement or heating
system, the ECL Comfort controller can be supple-
mented with a remote control unit, ECA 30/31, which
can be placed at any desired location in the building.
This enables room temperature monitoring and con-
trol, easy interfacing, and remote access for overriding
all the functions of the ECL Comfort controller.
