Program Lock (PL)
The Program Lock feature allows you to the lock the controls so that they are not inadvertently changed.
To activate the Program Lock, press and hold the + and
–
keys simultaneously for 20 seconds or until
‘
PL
’
is shown on the two-digit number screen. Do the same to remove the Program Lock.
Low TDS Mode (Two Decimals on Number Screen)
If the total dissolved solids (TDS) level of the water is low, the controller will go
into Low TDS Mode which is indicated by the two decimals on the screen coming
on. There is no impact to the performance of the system if it switches into Low
TDS Mode and these two decimals can be ignored. However, it is recommended
to test the TDS and increase if needed according to the levels given on page 9.
Low TDS Mode may be activated when the mineral cell is low. If the decimals appear but the TDS is
in range, check the c
ell. If the bars are worn down to 0.5” (10mm) or below it is time to change it.
