The display shows all status information about
the heating system. The time and the heating
program is shown in one of the displays which
can be selected as a favourite display. The display
is also used for the setting of control parameters.
Functions ECL Comfort 200 has a custom-designed display
with backlight for monitoring and setting.
The controller can be used as master or slave in
systems with master/slave controllers.
A remote control or room panel can be con-
nected to the system device bus.
Optional modules can be inserted into the
controller to obtain communication via MODBUS
or RS 232.
The Auto Tuning function for the automatic
setting of control parameters for instantaneous
domestic hot water production is available with
the ECL Card P16.
However, Auto Tuning is only applicable with
valves that are approved for Auto Tuning, i.e. the
Danfoss types VB 2 and VM 2 with split character-
istic as well as logarithmic valves such as VF and
VFS.
Motor protection, which ensures stable control
and a long life of the motorized valve, is available
with ECL Cards P16, P17 and P30.
