2.11.7 Fast access menu
The f ast access 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 f or "Probe not present" or "Value not evaluated".
"Err"
means "Value out of
range" or "Probe damaged, not connected or incorrectly configured".
Entering the fast
access menu
Press and release the
UP
arrow. In case of inactivity the
menu remains displayed for 3 minutes.
The values that will be displayed depend on the
conf iguration of the board.
Use the
or
arrow to select
an entry, then
press
to see the value
or to go on with
another value.
▪
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)
