6.3 DESCRIPTION OF PARAMETERS
[CoDE] – Access code (123):
Required if you want to change the parameters for advanced configuration. To view the set
parameters only, it is not necessary to insert this code.
[,F01] – Preferential indication:
This function allows you to choose the temperature that would normally be displayed on the display.
You can select between:
[,DIF]– T1-T2 Differential. Shows how many degrees is the difference between the solar
collector (T1) and the pool or thermal reservoir (T2).
[,,T1]– Temperature of collectors (T1).
[,,T2]– Temperature of 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 / thermal
reservoir to trigger the circulation pump. As the collectors receive energy, the T1 sensor temperature
increases when this temperature is above a certain value of the T2 sensor temperature, the pump is
turned on and circulates the heated water, storing it in the reservoir.
[,F03] – Differential (T1-T2) to turn off the pump:
Allows you to configure the temperature difference between the solar collector and the pool / thermal
reservoir to turn off the circulation pump. With the pump on, the temperature difference between the
collector and the reservoir (T1-T2) tends to decrease. When this value falls to a certain value, the
pump is turned off, stopping the water flow.
[,F04]– Antifreeze temperature (T1) to turn on the pump:
When the temperature of collectors (T1) is too low (ex.: winter nights) the pump is turned on,
depending on the temperature set this parameter to prevent the water from freezing in the solar
collector and damaging them. The hysteresis of this control is fixed and set at 2.0ºC. To disable this
function moves the setting to the minimum until [,,no] appears.
[,F05] – Minimum time of antifreeze:
This minimum time of pump on serves as security to ensure that water passes by all collectors. Even if
the temperature of T1 sensor exceeds the antifreeze temperature (parameter [,F04]), the
controller regards the time set in this parameter. This function is widely used in large projects by the
amount of installed plates. To disable this function moves the setting to the minimum until
[,,no]appears.
[,F06]– Overheating temperature (T1) to turn off the pump:
When the temperature in the collector (T1) is above the value set in this parameter, the pump is turned
off to prevent the heated water circulating through the pipes and damaging them, if PVC pipes are
used for example. The hysteresis of this control is fixed and set at 2.0ºC.
[,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):
Aims to cool the pool / thermal reservoir at night when 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 turned on, using the collector as a radiator to cool the pool water. When the
differential (T1-T2) is less than -2,0ºC (fixed) or temperature (T2) falls below 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].
There are models of vacuum tube collectors that do not allow direct measurement of the collector
temperature, for lack of foresight for immersion sensors.
For a correct measurement of the water temperature at the outlet of the collector is necessary that a
minimum water flow occurs. For this, the solar circuit must activate the pump at regular intervals, so that
heated water from the collector reaches the sensor T1.
Note: The controller prioritizes the protection settings (overheating), ignoring the function of the vacuum
tube, upon the occurrence thereof.
[,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 heating temperature of pool / reservoir (T2) [temp] parameter):
If the pump is stopped by heating of the reservoir ([temp]), using this function you can define a
temperature range within which the pump will remain off.
For example: If adjusted [temp]=[,30.0]and [,F14]=[,,1.0], pool / thermal reservoir heating
will turn off when the temperature of the T2 sensor reaches 30.0°C, and again just calling to heat when it
drops below 29.0°C (30.0 - 1.0 = 29.0).
[,F15]– Offset of T1 sensor indication:
[,F16]– Offset of T2 sensor indication:
To compensate possible misreading of T1 (collector) and T2 (reservoir) sensors from sensor
replacement or modification of cable length.
[,F17] – Time to lock functions:
Sets the time that must be held down the increment key to lock / unlock the parameter changes. For
further information see section 5.5 - Lock of Functions To disable this function moves the setting to the
minimum until [,,no] appears.
[,F18] – Display backlight intensity:
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).
Notes:
am pm
- If no 123 code has been inserted, when accessing the parameter setting
the icon will be displayed on upper display, indicate that the setting
is locked.
- By blocking the active functions to press or keys to change the value
of the function, the controller displays the [,LOC] [,,On] message on
display and you cannot make the parameter adjustment.
