4.2 Starting the chiller
• Connect the power supply to the machine by turning the main
isolator switch QS [P0] to ON.
• Turn the chiller ‘ON’ by pressing the key [P1].
• Set the desired temperature on the controller.
Phases Monitor
If appears on display the alarm “PI1/PI2 “, during the start up, the
user must verify the wiring of the input terminals of the disconnecting
switch.
4.2.1 Adjustments at commissioning
a) Temperature setting. To adopt a new setting, see heading 4.5.
b) Verify correct operation of the pump, using the pressure gauge (read
P1 and P0) and checking the pressure limit values (Pmax and Pmin)
indicated on the pump data plate.
P1 = pressure with pump ON
P0 = pressure with pump OFF
Pmin < (P1-P0) < Pmax
- Example n°1.
Conditions:
closed circuit, pressure P0 = 2 bar
pump data plate values: Pmin 1 bar/ Pmax 3 bar
adjust the valve outlet to give a pressure of 3 bar < P1< 5 bar
- Example n°2.
Conditions:
open circuit, pressure P0 = 0 bar
pump data plate values: Pmin 1 bar/ Pmax 3 bar
adjust the valve outlet to give a pressure of 1 bar < P1 < 3 bar
c) Verify correct operation of the pump similarly under normal running
conditions.
Check also that the amperage of the pump is within the limits indi-
cated on the data plate.
d) Switch off the chiller and proceed to top up the hydraulic circuit at
the “SET” temperature.
e) Check that the temperature of the “treated” water does not fall
below 5 °C and that the ambient temperature in which the hydraulic
circuit operates does not fall below 5 °C. If the temperature is too
low, add the appropriate quantity of glycol, as explained under head-
ing 3.3.2
4.3 Stopping the chiller
When chiller operation is no longer required, turn the chiller off as fol-
lows: press key [P2] to switch the controller ‘Off’.
Do not turn off the main switch QS [P0] to ensure that any antifreeze
protection devices will still receive electrical power.
4.4 Parameter settings
General
There are two levels of protection for parameters:
a) Direct (D): with immediate access, User-changeable;
b) Password protected (U): password required for access; Factory-set
parameters.
