11. MAIN PARAMETERS
Pump
The electronic board includes a pump control output.The pump
starts when the assembly is powered up and at least 285 seconds
before the compressor starts up and stops 120 seconds after the
assembly shuts down.
After the first 120 seconds of pump operation when the water flow
is at full speed,the water flow alarm functions are activated
(differential pressure switch and flow switch).
With a pump connected to terminals PL and PN on the installer
terminal board.
Fan speed control
For correct operation of the unit with different outside temperatures,
the microprocessor controls the fan speed based on the pressure
reading from the pressure probe, thus enabling heat exchange to
be increased and/or decreased,maintaining the condensing or
evaporation temperature practically constant.
The fan functions independently of the compressor.
Frost prevention alarm
To prevent the water freezing and damaging the plate heat
exchanger, the microprocessor shuts down the compressor if the
temperature measured by the heat exchanger outlet temperature
sensor is less than 3°C.
The frost prevention temperature set point can be modified by an
authorised service centre only and only after verifying that the water
circuit contains antifreeze.
Tripping of this alarm shuts down the compressor but not the pump,
which remains active.
To reset normal functions,the outlet water temperature must rise to
more than +15°C.Reset is manual.
If it is previewed not to use the machine for long periods After
deactivating the chiller:
-Make sure the model is in the Power off model " ", or
alternatively disconnect the unit from the power supply.
-Make sure the remote control switch is closed (if present) .
-Close the water valves.
If there is a possibility that the outside temperature may drop
below zero,there is the risk of freezing.
The water circuit MUST BE EMPTIED AND SHUT OFF
POWER (when draining after heat pump operation take care
as the water may be hot) or antifreeze must be added in the
proportion recommended by the manufacturer.

Water flow alarm
The microprocessor provides for management of a water flow
alarm controlled by a water flow switch fitted as standard on the
appliance and a flow switch to be installed on the water delivery
piping.
This safety device may trip after the first 120 seconds of pump
operation when the water flow is up to speed.
Tripping of this alarm shuts down the compressor but not the
pump,which remains active.
To reset normal functions,the alarm contact must be deactivated
for at least 15 seconds.
When condenser temperature over than 62°C, system will shut
down,but not returns to normal operation until the condenser
temperature decreased less than 52°C.
