Placed on high pressure side of cooling circuit, sig-
nals the work pressure to control board, generating a
pre-warning in case abnormal pressure occurs.
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/CEE
and 92/31/CEE.
Allows the complete control of the appliance.
For a more in-depth description please refer to the
user manual.
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 (with external
- Condensation check based on the pressure rather than on tem-
Inverse condensation check for the heat pump functioning mode
- 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.
