Description
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] - Maximum pump on time in manual mode:
It is the time the pump will remain in manual mode. After this period, the controller assumes the AUT
(AUTOMATIC) mode.
[,F08]– 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.
[,F09]– Vacuum tube function:
In case this function is enabled, the controller activates the pump for time set in [,f10] and
keeps the pump off for the time set in [,f11]. In order to perform this control, the collector (T1)
temperature must be higher than the value set in [,f12] and observe the maximum differential
set in [,f13].
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.
[,F10]- :Pump on time in the vacuum tube function
It is the time the pump will remain on when the vacuum tube function is active.
[,F11]- :Pump off time in the vacuum tube function
It is the time the pump will remain off when the vacuum tube function is active.
[,F12]- :Minimum temperature (T1) to switch the pump on in the vacuum tube function
It is the minimum temperature (T1) allowed to activate the vacuum tube function.
[,F13]- Maximum differential (T1-T2) for protection against thermal shock in the vacuum
tube function:
It is the maximum temperature difference allowed between T1 and T2 to switch the circulation pump
on. When the vacuum tube function is enabled, the protection against thermal shock is activated,
which prevents the circulation pump from being switched on when the collector temperature is much
higher than the tank.
[,F14]– 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 [,F14] = [,,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).
[,F15]– 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 this
parameter. To disable this function, move the setting to the minimum until [,,No] appears.
[,F16]– Filtering events schedule operating mode:
Sets the operating mode of the events schedule:
[,1b1]– Weekly Programming – in this mode, the instrument can set up to 4 different
events for each day of the week.
[,2t6]– Weekday Programming – in this mode, the instrument keeps events the same on
weekdays (Monday to Friday) and allows you to program different events for Saturday and
Sunday.
[,1t7]– Daily Programming – in this mode, the instrument keeps the events the same for
every day of the week.
[,F17]– T1 sensor indication offset:
[,F18]– T2 sensor indication offset:
Used to compensate for possible deviations in the T1 sensor (collector) or T2 sensor (pool) reading
as a result of sensor replacement or changing the cable length.
[,F19]– Function lock time:
Sets the time that the increment button must be pressed in order to lock/unlock parameter changes.
For more information see item 5.8 – Function Lock. To disable this function, move the setting to the
minimum until [,,No] appears.
[,F20]– Intensity of the display backlight:
If the value adjusted in this function is the minimum [,ECO], the intensity of the backlight of the
display will decrease to the minimum value (1) if no key is pressed for 5 seconds, If any key is
pressed, the intensity will increase to (8).

6.4 UNIT SELECTION
To define the temperature unit with which the instrument is going to operate you should
access the [Code] function (see article 6.1 to find out how to access this function), insert
the 231 code and press the key. The user may select the unit by pressing the keys or ,
where the messages [,=C,]or[,=F,]are alternated. Press the SET key to confirm
the desired unit. Next the message[----]will be displayed and the{or }icons
corresponding to the unit will be turned on.
Obs.: While changing the unit, the controller carries the factory values in its parameters,
[,FAC], being necessary to perform their setting.
