Introduction
1.2.3 Temperature sensors
If using an external valve driver (EVDice/mini) or on the MPXone Advanced version, a temperature probe for calculating the
superheat needs to be installed near the evaporator outlet. Suitable thermal insulation of the probes is recommended. CAREL
supplies probes designed to simplify installation in contact with the refrigerant piping:

Notice:
• the glass temperature probe must be connected to the coldest point of the showcase glass, for optimum operation of the
anti-sweat device (heaters or fans). See technical leafl et +050002005
• see manual +040010025 (ITA- ENG) /+040010026 (FRE-GER) for guidelines on installing the sensors on the unit.

1.2.4 Pressure sensors
If using an external valve driver (EVDice/mini) or on MPXone Advanced, to measure the saturated evaporation pressure/tem-
perature (PEu/tEu), diff erent types of probes can be used; specifi cally (by setting parameter /P2, /P3,/P2) the following can be
installed:
• 0-5 V / 0.5 Vdc-4.5 Vdc ratiometric pressure probe (recommended by CAREL);
• 4-20 mA active pressure probes.
