of water to be sent to the utilities.
6.5. SAFETY AND CONTROL COMPONENTS
HIGH PRESSURE SWITCH
With fixed calibration, placed on high pressure
side of cooling circuit, inhibits functioning of
compressor if abnormal work pressure occurs.
HIGH PRESSURE TRANSDUCER
Placed on high pressure side of cooling circuit,
signals the work pressure to control board,
generating a pre-warning in case abnormal
pressure occurs.
LOW PRESSURE TRANSDUCER
Allows displaying, on the microprocessor board
display, the value of the compressor's suction
side of the cooling circuit.
6.6. ELECTRIC COMPONENTS
Electric Control Board
Contains the power section and the man-
agement of controls and safety devices.
It is in compliance with the IEC 60204-1
Standard and the Directives regarding
electromagnetic compatibility EMC 89/336/
EEC and 92/31/EEC.
Door-lock isolating switch
The electric control board can be ac-
cessed by removing the voltage. Act on
the opening lever of the control board itself.
This lever can be locked using one or more
padlocks during maintenance interventions
to prevent the machine being powered up
accidentally.
Allows complete control of the appliance.

MODU CONTROL
Temperature control of the output water with proportional-integral
algorithm: maintains average output temperature at value set
- Self-adapting differential switch: guarantees minimum functioning
times of the compressor in systems with low water content.
- Intelligent defrosting for pressure reduction: allows to determine
when the coil is effectively defrosted, avoiding useless defrosting
- Set-point compensation with external temperature: reduces energy
consumption
- Pre-alarms with automatic reset: in the case of alarm, a certain
number of re-starts are allowed before the definitive block
blocked cycle reversing valve
- Compressor functioning hours count.
- Compressor peak count.
- Historical alarms
- Autostart after voltage drop.
- Local or remote control
