MODUCONTROL
CONTROL PANEL
5.6. ELECTRIC COMPONENTS
Electric Control Board
Contains the power section and the management of
controls and safety devices. It is in compliance with
the IEC 60204-1 Standard and the Directives regard
-
ing electromagnetic compatibility EMC 89/336/EEC
and 92/31/EEC.
Door-lock isolating switch
The electric control board can be accessed by re-
moving the voltage. Act on the opening lever of the
control board itself. This lever can be locked using
one or more padlocks during maintenance interven-
tions to prevent the machine being powered up
accidentally.
Control board
Allows complete control of the appliance.

Electric Regolation
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
alarm on the ∆T: to identify wiring errors (reverse rotation) or
blocked cycle reversing valve
- Compressor functioning hours count.
- Compressor peak count.
- Historical alarms
- Autostart after voltage drop.
- Local or remote control
