5.4 Safety and control components

High pressure switch

Placed on high pressure side of the the refrigeration circuit the
high pressure switch prevents the compressor from operating if
abnormal working. This switch is calibrated during manufacture
and should not be adjusted by the installer.

Low pressure transducer

Placed on the low pressure side of the refrigeration circuit, it
measures the working pressure and generates a pre-warning in
case an abnormal pressure occurs.

High pressure transducer

Placed on the high pressure side of the refrigeration circuit, it
measures the working pressure and generates a pre-warning in
case an abnormal pressure occurs.

5.5 Electric components

Control board

Controls all aspects of the heat pump operation.

5.6 Electronic control

Modu-Control

The controller allows: 

„

Temperature control of the output water with proportional-in-
tegral algorithm: maintains average output temperature at
value set

„

Intelligent defrost program uses pressure drop in the refrig-
eration system to determine when the coil is effectively de-
frosted, avoiding unnecessary defrosting

„

Defrosting by cycle reversing: to overcome more extreme
ambient conditions

„

Weather compensation set point control as standard

„

Condensation check based on the pressure rather than on
temperature for absolute stability (with revs. adjuster acces-
sory )

„

5 temperature probes and 2 pressure transducers

„

Pre-alarms with automatic reset: in the case of alarm, a cer-
tain number of re-starts are allowed before the heat pump is
blocked from operation

„

Alarm on the 

Δ

t: to identify wiring errors (reverse rotation) or

blocked cycle reversing valve

„

Compressor functioning hours count

„

Compressor peak count

„

Historical alarms

„

Auto-start after voltage drop

„

Local or remote control (remote control is supplied as op-
tional extra)

„

Display of the state of the unit:
a) Voltage presence
b) Compressor ON/OFF
c) Current operation mode (Heating / Cooling)
d) Alarm active indication

„

Probes, transducers and parameters display
a) Water outlet
b) Water inlet
c) Coil temperature
d) Pressing line gas temperature
e) External air temperature (heat pumps with DCP)
f) Flow pressure
g) Intake pressure
h) Temperature error (sum of the proportional and integral

error)

i) Stand-by times for start-up/switch-off of the compressor

„

Alarms management
a) Low pressure
b) High pressure (primary alarm: switch directly blocks sup-

ply to compressor)

c) High discharge temperature
d) Anti-freeze
e) Water differential pressure switch
f) Alarm on the
