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 sttoped.
DF.03 - Minimum T2 superheat temperature setpoint (pool/ reservoir) allowed to the
user:
Allows you to configure the minimum T2 superheat temperature limit (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 T2 (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
superheat.
DF.06 - T2 superheat temperature hysteresis to restart the pump:
If the pump is turned off due to superheating 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 start 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 2ºC.
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 superheat water from circulating through the pipes and
damaging them, if PVC pipes are use, for example. The hysteresis of this control is fixed and
se 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.
DF.14 - Pump off time - scan mode:
It is the time that the pump will remain off in scan mode.
DF.15 - Maximum differential (T1-T2) for thermal shock protection:
It is the maximum temperature difference between sensors T1 and T2 allowed to start the
circulation pump. When enabled, protection against thermal shock is activated, which
prevents turning on the circulation pump when the collector temperature is much higher than
the thermal reservoir, preventing damage to the solar collector.
DF.16 - Circulation pump type:
Allows you to select which type of circulation pump will be used in the installation:
STD - standard - ON/OFF relay;
PWM - pulse width modulation pumps;
LIN - linear 0-10V - analog output for variable speed pumps.
DF.17 - Differential setpoint (T1-T2) (variable speed pump):
It is the differential setpoint configured to calculate the speed of the variable speed pump.
When the differential (T1-T2) is greater than this parameter, the pump speed increases
according to the increment rate set in DF.18.
DF.18 - Increment rate (variable speed pump):
It defines the rate of increase of the variable pump speed when the differential (T1-T2) is
greater than the value configured in parameter DF.17. Pump speed is incremented by 10%
whenever the differential (T1-T2) exceeds the increment rate (DF.18) above the differential
setpoint (DF.17).
DF.19 - Minimum pump speed (variable speed pump):
Allows you to configure the minimum speed that the variable speed pump will operate when it
is turned on.
DF.20 - Maximum pump speed (variable speed pump):
Allows you to configure the maximum speed that the variable speed pump will operate when
it is turned on.
DF.21 - Pump start time at maximum speed (variable speed pump):
It is the minimum time that the pump will turn on at maximum speed (set in DF.20) when
turned on. After this time, the pump speed is defined by the calculation according to
parameters.
A1.01 - Auxiliary 1 operating mode:
Sets auxiliary 1 operating mode:
OFF = off; HOT = heating thermostat;
ON = on / cyclic; REF = refrigeration thermostat.
A1.02 - Auxiliary 1 reference temperature sensor:
Choose the temperature sensor that will be used to control auxiliary 1.
A1.03 - Minimum temperature setpoint of auxiliary 1 allowed to the user:
A1.04 - Maximum temperature setpoint of auxiliary 1 allowed to the user:
These parameters serve as lower and upper setting limits for parameter A1.SP. They are
used to lock the temperature setting to the end user to restrict an inappropriate setting. For
example, a high value can keep the auxiliary output on for a long time, resulting in high energy
consumption.
A1.05 - Auxiliary 1 temperature setpoint:
Sets the desired control temperature for auxiliary 1.
A1.06 - Auxiliary 1 temperature setpoint Economic:
Sets the desired temperature for auxiliary 1 when economizer mode is activated. One
possible application for economy mode is use on underfloor heating, in order to keep the floor
preheated and allow for rapid heating of the space when necessary.
Note: Eco mode is activated by configuring the event schedule.
A1.07 - Auxiliary 1 operating hysteresis:
Temperature difference to turn on the auxiliary output. Through this function it is possible to
define a temperature range within which the output will remain off.
For example:
If A1.SP = 45 and A1.07 = 1, are set, the auxiliary output will turn off when the
temperature reaches 45°C and turn on again when it drops below 44ºC.
A1.08 - Auxiliary 1 manual activation time:
Used when the user wants to eventually activate the auxiliary output outside the scheduled
time in the event schedule. During this time, the auxiliary output is controlled according to its
operating mode, for example, linked to the temperature if A1.01 = HOT (heating
thermostat) or REF (cooling thermostat). From manual activation, after the time
programmed in this parameter has elapsed, the auxiliary mode returns to AUT (automatic)
mode.
Note: This function can be turned off by setting it to the minimum value OFF.
A1.09 - Cyclic timer on time / scan time (recirculation):
If A1.01 = ON (on / cyclic): Time that auxiliary output 1 will be on.
If A1.01 = HOT (heating thermostat): Time in which the controller will keep the water
circulation activated to equalize the water temperature in the barrel.
Note: This function can be turned off by setting it to the minimum value OFF.
