Cover mode
This mode concerns pools equipped with a cover and a system that detects when the cover is deployed
over the pool and closes a dry contact.
This is mainly useful for pools fitted with the EES model because this model does not regulate the
concentration of Chlorine in the water but rather produces Chlorine for as long as the filtration cycle is
running. While the cover is deployed over the pool, the free Chlorine is protected from destruction by UV
radiation and is not being consumed by pollution introduced by bathers, therefore there is a risk that it will
accumulate in the water while filtration is running.
The two wires of the dry contact should be connected to the COVER terminal in the control panel (see
paragraph 4), and the contact should close when the cover is deployed over the pool.
While the cover is deployed, the message MODE AUX is displayed on the panel's LCD screen, and the
production of Chlorine is decreased to 20% by default.
The value by which Chlorine production is decreased while the pool is covered may be modified by the
user using the arrow keys ▼ and ▲.
The new value will be saved automatically, this will then be the Chlorine output in Cover mode until the
value is modified again.

Descaling the cell by injecting acid using the acid dosing pump
Reminder: the acid dosing pump is an integral part of EES Pro, and is available as an option for EES.
The automatic electrode polarity switching system helps slow, and evenly distributed deposition of scale
on the electrodes in the cell (see paragraph 1 for the explanations).
Nevertheless, and even if the concentration of calcium dissolved in the water is within allowed limits, there
is a risk that this phenomenon will occur.
The scaling phenomenon may be counteracted by programming the injection of small quantities of acid
(approx 70 cm3) into the cell using the acid dosing peristaltic pump while filtration is stopped (Stand-by
mode). The acid injection frequency is set as follows:
•
stop filtration
•
press the
button to enter CELL CLEANING – AUTO mode
•
choose an injection frequency (LVL) between 0 and 9 using the arrow keys ▼and ▲ according to the
following table:
LVL
0
Min. filtration
No
duration
injection
(hours) prior
to injection
To cancel periodic injections of acid, set the level LVL to 0.
Nota bene: for EES Pro the factory setting is LVL = 9.
