Door interlocked isolator
Access to the electrical panel is by operating the handle of the door interlocked
isolator which removes power to the unit.
To avoid accidentally powering up the unit during maintenance the isolator is fitted
with a locking mechanism.
Controller keypad
Allows complete control of the unit.
For further information refer to the user manual.
Electronic controller
The microprocessor controls features cutting edge functions and proprietary ad-
justments.
The control panel allows the user to consult and manage the unit operating param-
eters thanks to a purposely designed multi-language graphic interface.
The multi-level menu can be used to control:
— The system temperature for cooling the environments or industrial processes.
The different temperatures are managed automatically according to the unit
work conditions and requirements.
— Management and alarm log to have always a prompt diagnosis of the unit op-
eration.
— Creation of operation time periods required for efficient programming
— A self-adaptive logic is used to defrost. This logic allows you to adjust the num-
ber of defrosts in order to increase efficiency.
— Systems consisting of two chillers allow the unit to be adjusted via (Master/
Slave), supplied as per standard. In case of several chillers through the Mul-
tichiller_EVO. The supervision is possible thanks to different options, with pro-
prietary devices or by integrating other systems via ModBus, Bacnet, LonWorks
etc. protocols.
A specific keyboard for wall-mounting installation (PGD1 accessory) allows the re-
mote control of all the functions.
Note: For further information, refer to the user manual.
