7.5. Low temperature
The need for disinfectant is greatly reduced when the water temperature falls. So as not to needlessly
use the electrolysis cell, the device suspends production when the water temperature is below 12°C
and displays
T=
. In shock mode (
P8
) the production works even if the temperature is low..
7.6. Automatic cover
If the
ZLT
is connected to your automatic cover, it detects that the cover is closed, activates the
indicator
and divides by 4 the projected chlorine production period. This functionality
means that the risk of a significant accumulation of chlorine is reduced. For instance, if the normally
projected production cycle is expected to last 8 hours, the production is reduced to 2 hours when
the cover is closed.
7.7. Redox-controlled production
Take care not to use the
PA
mode unless you have a RedOx regulator. In this
mode with this external regulator, the switch of the supply must be set to
"EXT".
This mode (
PA
) means that the chlorine production can be regulated according to actual requirements
when the
ZLT
is connected to a redox or chlorine measuring device (sold separately). The "Cover"
entrance of the
ZLT
is then used to connect the contact switch of the measuring device. When the
RedOx or rate of chlorine measured is less than the recommended amount, the analyzer dry contact
is closed and the
ZLT
is in production mode (if filtration is in operating mode).
7.8. Display of parameters
It may be useful to display some parameters which determine the way in which the device operates.
These parameters are viewed by pressing the button
and
. In order to identify the para-
meter, its number is alternated, preceded by a
o
.
Parameter
Description
o1
Remaining electrolysis duration in hours, or in minutes when the point sepa-
rating the 2 displays is lit
o2
Duration of electrolysis completed (hours) since the start-up of the program
in progress
o3
*
Electrolysis current (1.0 = 1,0A)(2.0 = 2,0A)(3.0 = 3,0A) through the plates.
o4
*
Conductivity (in mS/cm) on indicative basis. This value is calculated according
to the voltage, current and temperature on the theoretical basis of a new cell
(doesn't take into account wear and tear of the plates).
o5
(editable)
Water hardness to enter for an optimal calculation of the polarity inversion
cycles (refer to section "Water hardness").
