Connect 1 to 4 contacts to the terminals of the connector of the
CPU board according to the number of the compressors to be
shed. 1 contact per compressor (contact free of any polarity
and of good quality).
• Contact open → normal operation,
• Contact closed → compressor load shedding.
• Input specification: 24 V - 15 mA.
NOTE:
• Connection to be made on site by the customer,
• Precautions for connection. See manual for the regulator
and the electrical diagram of the unit.
Communication
• In the room, a control and display console is used to
run an instant check on the unit; it enables the user to
communicate with the microprocessor, to configure the unit
and to adjust the setpoints.
• Electronic remote control (option):
Installed in the machine room, this will be connected to
the unit by a pair of telephone-type wires (max. distance
1000 m). Description of functions and connection: see
CONNECT2 manual.
• Relay board(s) (option):
This board is installed in a cabinet in the machine room and
can remotely report on all the unit's operating states and
faults by providing contacts which are potential-free when
closed. The board will be connected to the unit by a pair of
telephone-type wires (max. distance 1000 m).
Description of functions
CONNECT2 manual.
• Communication with centralised management system
(option).
• See possibility in CONNECT2 manual.
The electronic module controls the operation of the
compressors. Thus, depending on the difference between the
cold water (or hot water) return temperature and the setpoint
