4.3 Guided commissioning procedure (user
terminal/remote display)
When fi rst powered up, MPXPRO runs a procedure that guides the user in
setting the main parameters for the confi guration of the electronic valve
and the serial network.
Start-up parameters
Par. Description
/P2 Type of probe, group 2 (S4, S5)
/P3 Type of probe, group 3 (S6)
/Fd Assign tGS (superheated gas temperature probe)
/FE Assign PEu/tEu (saturated evaporation pressure/temperature probe)
/U6 Maximum value of probe 6
/L6 Minimum value of probe 6
P1 Electronic valve
PH Type of refrigerant
In Type of unit
Sn Number of slaves in the local network
H0 Serial or Master Slave network address
The parameters can be confi gured from the user terminal or the remote
control. If using the remote control, a terminal with display and infrared
receiver (IR) is required.
After having powered up the controller:
1. the fi rst parameter is displayed: /P2 = type of probe, group 2 (S4, S5);
2. press Set to display the value of the parameter;
3. press UP/DOWN to change the value;
4. press Set to confi rm, the "spanner" icon disappears, indicating that the
setting has been made;
5. press UP and repeat steps 2, 3, 4 for the following parameters, /P3, /Fd,
/FE, /U6, /L6, P1, PH, In, Sn, H0;
6. press Prg/mute for 5 seconds to exit the guided commissioning
procedure.

/P2: Type of probe, group 2 (S4,S5)
Used to select the type of temperature probe to be used for inputs S4, S5.
Par. Description
/P2 Type of probe, group 2 (S4, S5)
0 = NTC Standard Range –50T90 °C
1 = PTC Standard Range –50T150 °C
2 = PT1000 Standard Range –50T150 °C
3 = NTC L243 Standard Range –50T90 °C
Note: NTC L243/PTC/PT1000 probes can only be set in the full
optional models or models with EEV driver. To assign the functions
to the other probes, see parameters /FA, /Fb, /Fc, /Fd, /FE,
/FF, /FG, /FH, /FI, /FL, /FM. For probe calibration, see parameters /c4,/c5.
/P3: Type of probe, group 3 (S6)
Used to select the type of temperature or ratiometric pressure probe to
be used for input S6.
Par. Description
/P3 Type of probe, group 3 (S6)
0 = NTC Standard Range –50T90 °C
1 = PTC Standard Range –50T150 °C
2 = PT1000 Standard Range –50T150 °C
3 = NTC L243 Standard Range –50T90 °C
4 = 0 to 5V ratiometric probe
Note: NTC L243/PTC/PT1000 can only be set in the full optional
models or models with EEV driver.
/Fd: Assign tGS (superheated gas temperature probe)
Used to assign the measurement of the superheated gas temperature at
the evaporator outlet to the selected probe.
Par. Description
/Fd Assign tGS (superheated gas temperature)
0 = Funct. disab. 6 = Probe S6
1 = Probe S1 7 = Probe S7
2 = Probe S2 8 = Serial probe S8
3 = Probe S3 9 = Serial probe S9
4 = Probe S4 10 = Serial probe S10
5 = Probe S5 11 = Serial probe S11
/FE: Assign PEu/tEu (saturated evaporation pressure/temperature
probe)
Used to assign the measurement of the saturated evaporation pressure/
temperature to the selected probe, which by default is the probe
connected to input S6. The 0 to 5 Vdc ratiometric probe is recommended.
Par. Description
/FE Assign PEu/tEu (saturated evaporation
pressure/temperature probe)
See /Fd
/U6, /L6: Maximum / minimum value of probe S6
Parameters /L6 and /U6 are used to adjust the maximum and minimum
limits corresponding to the range of measurement for the probe
connected to input S6.
Par. Description
/U6 Maximum value of probe 6
/L6 Minimum value of probe 6
P1: Type of expansion valve
MPXPRO can control the CAREL E
depending on the model code.
Par. Description
P1 Electronic valve
0 = not used
1 = PWM valve
2
2 = CAREL E V valve
