6.3 DESCRIPTION OF PARAMETERS
[Code]
– Access code (123):
Required when you want to change the advanced configuration parameters. This code is not
required to only view the set parameters.
[,F01]
– Preferred indication:
This function allows you to choose the temperature that is normally shown on the display. You
can choose between:
[,DIF]
– T1-T2 differential. Shows the temperature difference in degrees between the
solar collector (T1) and pool (T2).
[,,T1]
– Temperature of the collectors (T1).
[,,T2]
– Temperature of the pool/thermal reservoir (T2).
[,F02]
– Differential (T1-T2) to turn on the pump:
Allows you to configure the temperature difference between the solar collector and the pool at
which the circulation pump is switched on. As the collectors receive energy, the temperature of
sensor T1 increases. When this temperature is a set value above the temperature of sensor T2,
the pump is switched on and circulates the heated water, storing it in the pool.
[,F03]
– Differential (T1-T2) to switch off the pump:
Allows you to configure the temperature difference between the solar collector and the pool at
which the circulation pump is switched off. With the pump on, the temperature difference
between the collector and the pool (T1-T2) tends to decrease. When this value falls to a set
value, the pump is switched off, stopping the circulation of water.
[,F04]
– Antifreeze temperature (T1) to switch the pump on:
When the temperature of the collectors (T1) is very low (e.g. winter nights), the pump is switched
on according to the temperature set in this parameter, in order to prevent water from freezing in
the solar collector
and damaging them. The hysteresis of this control is fixed and set at 2.0 ºC.
To disable this function, move the setting to the minimum until
[,,No]
appears.
[,F05]
– Minimum antifreeze time:
This minimum time with the pump switched on serves as a safety measure to ensure that the
water passes by all the collectors. Even if the temperature of the T1 sensor exceeds the
antifreeze temperature (
[,F04]
parameter), the controller respects the time programmed in
this parameter. This function is often used in large projects due to the number of installed plates.
To disable this function, move the setting to the minimum until
[,,No]
appears.
[,F06]
– Overheating temperature (T1) to switch off the pump:
When the temperature in the collectors (T1) is above the value set in this parameter, the pump is
switched off to prevent the overheated water circulating through pipes and damaging them, if
PVC pipes are used, for example. The hysteresis of this control is fixed and set at 2.0 ºC.
[,F07]
– Cooling (T2):
This is intended to cool the pool during the night whenever the heating temperature (
[TEMP]
parameter) is exceeded and the difference between the collector (T1) and reservoir (T2)
reaches -4.0 °C (fixed). The pump is then switched on, using the collector as a radiator to cool
the pool water. When the differential (T1-T2) is less than -2.0 °C (fixed) or the temperature (T2) is
lower than the heating temperature of the reservoir (
[TEMP]
parameter), the pump is switched
off.
[,F08]
– Vacuum tube function:
When enabled, this function switches the pump on for 20 seconds (fixed) for every 30 minutes
(fixed) the pump is switched off, while the collector temperature (T1) is above 20.0 °C (fixed) and
the temperature differential (T1 -T2) is positive.
Some models of vacuum tube collectors do not allow direct measurement of the collector
temperature since they are not set up for immersion sensors. For correct measurement of the
water temperature at the collector output, there must be a minimum flow of water. For this
reason, the solar circuit must switch on the pump briefly, at regular intervals, so that the water
heated by the collector reaches the T1 sensor.
Note:
The controller prioritizes the protection settings (overheating), ignoring the vacuum tube
function in the event both of these functions are called at the same time.
[,F09]
– Hysteresis of the pool heating temperature (T2):
If the pump is switched off due to reservoir heating (
[TEMP]
), this function allows you to set a
temperature range within which the pump will remain switched off.
For example: If set to
[temp]
=
[,30.0]
and
[,F09]
=
[,,1.0]
, the pool heating will be
switched off when the temperature of sensor T2 reaches 30.0 °C, and will only switch on in order
to heat when the temperature falls below 29.0 °C (30.0 - 1.0 = 29.0).

– Filtering manual override time:
Used when you wish to activate the filtering output outside the hours set in the events schedule.
When using manual override, the mode returns to AUT (automatic) after the time programmed in
