2.10.6 Entering programming level 2 "Pr2"
To enter the Pr2 programming menu:
▪ Press simultaneously for 3 seconds. The first parameter label will be displayed.
▪ Press till the T18 label is displayed, then press the key;
▪ The blinking PaS label will be displayed; wait for a few seconds;
▪ The display will show "0 - -" with blinking 0: insert the password [321] using the and keys
and confirming with the key.
2.10.7 Fast access menu
This menu contains the list of probes and some values that are automatically evaluated by the board
such as the superheat and the percentage of valve opening. nP or noP stands for "probe not present"
or "value not evaluated", Err means "value out of range", "probe damaged, not connected or
incorrectly configured".
Press and release the UP arrow. The duration of the
menu in case of inactivity is 3 minutes.
The values that will be displayed depend on the
configuration of the board.
▪ P1P: Pressure value of the P1 probe (suction pressure)
▪ P2t: Temperature value of the P2 probe (not valid)
▪ P2P: Pressure value of the P2 probe (discharge pressure)
▪ P3t: Temperature value of the P3 probe (discharge line
temperature)
▪ P4t: Temperature value of the P4 probe (vapour in only for ZXLE)
▪ P5t: Temperature value of the P5 probe (vapour out only for ZXLE)
▪ P6t: Temperature value of the P6 probe (ambient temperature)
▪ P7t: Temperature value of the P7 probe (free)
▪ SH: Value of superheat. nA = not available
▪ oPP: Percentage of step valve opening.
▪ LInJ: Status of the liquid line solenoid ("On" – "Off"). This information
is available only if one relay is set as "Liquid Line Solenoid".
▪ SEtd: Value of the dynamic setpoint (condenser fan SET). This
information is available only if the dynamic setpoint function is
enabled.
▪ AOO: Percentage of the analog output (0-10V or TRIAC PWM
Mod.). This information is available only if the 0-10V or TRIAC PWM
Mod. is enabled.
▪ dStO: Percentage of the PWM output driving the valve of the Digital
Scroll compressor.
▪ L°t: Minimum room temperature.
▪ H°t: Maximum room temperature.
▪ HM: Menu.
▪ tU1: Voltage reading V1 (not valid in standard configuration)
▪ tU2: Voltage reading V2 (not valid in standard configuration)
▪ tU3: Voltage reading V3 (not valid in standard configuration)
▪ tA1: Current reading I1
▪ tA2: Current reading I2
