P1: Type of electronic expansion valve
Code Description Def Min Max UOM User User terminal
P1 Electronic valve type
0 = not used/thermostatic valve
1 = CAREL unipolar E2V (MPXone Advanced)
2 = CAREL E2V driver and valve (superheat probes connected to the controller)
3, 4, 5 = reserved
6 = CAREL E2V driver and valve (superheat probes connected to the driver)
7 = PWM valve (0-10 V)
101- S YES
(*): for MPXone Advanced the default value is P1=1.
Notice: Using PWM valves requires a solid state relay (SSR) between the controller and the valve.
PH: Type of refrigerant
The type of refrigerant is essential for calculating the superheat value. In addition, it is used to calculate the evaporation and
condensing temperature based on the pressure probe reading. The table of predefined refrigerants is shown below.
