9.2 PARAMETERS DESCRIPTION
CODE - Access code:
It is necessary when you want to change the configuration parameters. To only visualize
the adjusted parameters it is not necessary to insert this code.
Code 231 - Technician
Code 123 - Advanced
DF.01 - Differential (T1-T2) to start the pump:
Allows you to configure the temperature difference between the solar collector and the
thermal reservoir to activate the circulation pump. As the collectors receive energy, the
temperature at sensor T1 increases, and when this temperature is a certain value above
the temperature at sensor T2, the pump is turned on and the heated water is stored in the
thermal reservoir/pool.
DF.02 - Differential (T1-T2) to turn off the pump:
Allows you to configure the temperature difference between the solar collector and the
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 decreases to a certain value, the pump is turned off and the water circulation is
stopped.
DF.03 - Minimum T2 superheat temperature setpoint (pool/reservoir) allowed to
the user:
Allows you to configure the minimum threshold for the superheat temperature T2
(DF.05).
DF.04 - Maximum T2 superheat temperature setpoint (pool/reservoir) allowed
to the user:
Allows you to configure the maximum T2 superheat temperature limit (DF.05).
DF.05 - T2 superheat temperature to turn off the pump:
This is the maximum desired temperature in the reservoir above which the circulating
water pump will not operate. This is a safety measure to protect the hydraulic installation in
case of overheating.
DF.06 - T2 superheat temperature hysteresis to restart the pump:
If the pump is turned off due to overheating in sensor T2 (DF.05), this function can be
used to define a temperature range within which the pump will remain off.
DF.07 - T1 antifreeze temperature to turn on the pump:
When the temperature of the collectors (T1) is very low (e.g., on winter nights) the pump is
switched on depending on the temperature set in this parameter. The goal is to prevent
water from freezing in the solar collector and damaging it. The hysteresis of this control is
fixed and set at 2°C.
Note: This function can be turned off by setting it to the minimum value OFF.
DF.08 - Minimum antifreeze time:
This minimum pump on time acts as a safety measure to ensure that water circulates
through all collectors. Even if the temperature of sensor T1 exceeds the antifreeze
temperature (parameter DF.07), the controller respects the time programmed in this
parameter. This feature is widely used in large works due to the number of collectors
installed.
Note: This function can be turned off by setting it to the minimum value OFF.
DF.09 -T1 superheat temperature to turn off the pump:
When the temperature in the collectors (T1) is above the value set in this parameter, the
pump is turned off in order to prevent superheated water from 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°C.
DF.10 - Pump on time in manual mode:
It is the time that the pump will remain on in manual mode. After this period, the controller
assumes the AUT (automatic) mode.
DF.11 - Temperature at sensor T3 to turn off cooling in Holidays mode:
Its purpose is to cool the thermal reservoir during the night when the Holidays mode is
activated. When the temperature of sensor T3 is higher than the value set in this
parameter and meets the internally defined temperature differentials, the pump is turned
on using the solar collector as a radiator to cool the water in the pool/reservoir. The
hysteresis of this control is fixed and set at 2°C.
Note: When deactivating sensor T3, the temperature of this control is referenced by
sensor T2.
DF.12 - Minimum temperature T1 to turn on the pump - scan mode:
It is the minimum temperature (T1) required to turn on the pump output depending on the
scan mode.
DF.13 - Pump on time - scan mode:
It is the time that the pump will remain on in scan mode.
Note: This function can be turned off by setting it to the minimum value OFF.
