CR - Remote Control. This device consists of a remote control
which allows all the control and monitoring functions of the control
unit on the machine to be controlled up to 100 meters away from the
actual machine itself. It has been specially designed for installation
on a wall inside the building. Use a threepole. The transmission line
must be routed in a dedicated duct, separate from any electric
powering lines (230/400 V). It has four keys used to select the con-
trols on the controller installed on the machine, the only difference
being that the scroll-up and scroll-down functions have been sepa-
rated from the mode and on-off keys in order to make the control
easier to use.
During normal operation, the operating temperature (or the temperature read by the probe on the exchanger inlet) in
degrees centigrade appears on the LCD display or the alarm code, if at least one is activated. The temperatures read
by the other probes can be read by means of a few simple operations.
If faults occur during normal operation, the controller stops the machine and displays the code of the alarm in question.
After the alarm has been checked and its cause eliminated, the controller can be reset by pressing the on/off key.
The remote control has the following keys:
The controller has five LEDs on the left-hand side of the interface, that display the status functions of the machine:
• LED of compressors 1 and 2 (circuit 1).
