Indicators - What They Mean
Output readings on the DIGITAL DISPLAY can fall due to any (or combination of) the following: cooler
water temperatures, warming of power supply (in heated equipment rooms for example), lower th an
normal power voltage, lower salt levels, scaling occurring on ‘Cell’.
Provided LED 1 and LED 2 are both GREEN ( and t he ‘Cell’ is not scaling excessively), your ECO-
matic is performing (producing) satisfactorily.

What's
Happening
STAND-BY ON Blank Green Green 1. Unit is in start-up mode
2. "Cell" is OFF cycle during normal operation
(refer System Control)
3. System Control set at MIN.
FLOW ON Blank Green Green 1. Insufficient flow through "Cell"
(Gas or air at Stand-By on "Cell", check
pump/pipes for damage, leaks)
2. Gas Sensor lead not connected to "Cell"
3. System is wired incorrectly.
Approx Green Green System operating normally.
90-100
Approx Green Red 1. "Cell" is dirty, scale build up.
90-100 Clean cell
2. Water Temperature Cold. Switch to Winter Mode
3. Salt level below min. Add salt
4. "Cell" failing. Test and/or replace "cell"
Varying Red Red Unit preparing to Cut-Out. (See low Salinity
Indicator and cut out).
1.
'Cell" is dirty, scale build up. Clean cell
2.
Water Temperature Cold. Switch to Winter Mode
3.
Salt level below min. Add salt
4. "Cell" failing. Test and/or replace "cell"
STAND-BY ON Blank Red Red System protection activated. Unit has Cut-Out.
Follow above procedures.
WINTER MODE ON Approx Green Green System operating normally - in Winter Mode.
75-85 Only operate in Winter mode if water is very cold.
Red LED(s): scaled "Cell" or low salt level.
