Antifreeze S1 to switch on the pump
It allows setting the temperature for which the collectors start to ice. When the temperature at the
collectors (sensor 1) is too low (e.g. winter nighttime), the pump is switched on at regular intervals to
prevent the water from freezing and damaging the pipes. To deactivate this function, just decrement the
value until the message is displayed.
Antifreeze hysteresis
Hysteresis for the antifreeze function to switch off the water circulation pump.
Minimum antifreeze time
Minimum time for which the antifreeze function stays on even if the temperature at sensor 1 returns to
the normal value.
Overheating temperature S1 to switch off the pump
It allows setting the overheating temperature of the collectors to switch off the water circulation pump.
When the temperature at the collectors (sensor 1) is higher than an adjustable value, the pump is
switched off to prevent the overheated water from circulating through the pipes and damaging them (if
PVC pipes are used).
Overheating hysteresis to switch on the pump
Overheating temperature hysteresis adjustment for sensor 1 to allow switching on the pump again
Overheating temperature S2 to switch off the pump (swiming pool temperature)
It allows setting the overheating temperature of the swimming pool to switch off the water circulation
pump to avoid uncomfortable thermal conditions.
Overheating hysteresis to switch on the pump (S2)
Overheating temperature hysteresis adjustment for sensor 2 to allow switching on the pump again.
Solar backing 1 operating mode
It allows setting up the operating mode of the solar backing 1 output. The modes are:
Solar backing 1 working independently from solar backing 2
Solar backing 1 deactivated when solar backing 2 is activated
When this parameter has the value "1" and the solar backing 2 is activated the controller will display the
message AA2. This option is used with solar heating systems containing gas (AUX1 output) and
electrical (AUX2 output) heating backups. In this condition when the controller activates the solar
backing 2 (electrical heating) it will alert the user that solar backing 1 (gas heating) is not working
properly.
Solar backing 1 temperature setpoint
Allows setting the activation temperature for solar backing 1.
Solar backing 1 activation hysteresis
Hysteresis setting for solar backing 1 activation temperature setpoint.
Minimum value for solar backing 1 temperature setpoint
Lower threshold aimed at preventing an exceedingly low temperature setpoint from being adjusted
inadvertently for solar backing 1.
Maximum value for solar backing 1 temperature setpoint
Upper threshold aimed at preventing an exceedingly high temperature setpoint from being adjusted
inadvertently for solar backing 1.
Solar backing 1 manual activation time
Time for which solar backing 1 stays on when activated manually. After this time solar backing 1 returns
to automatic operation.
Solar backing 2 operating mode
It allows setting up the operating mode of the solar backing 2 output. The modes are:
Cooling thermostat
Heating thermostat
Cooling thermostat linked to the event schedule
Heating thermostat linked to the event schedule
Cyclic timer with initial state "off"
Cyclic timer with initial state "off" and linked to the event schedule
Cooling thermostat for heat dissipation to reduce any excess temperature in the water
tank.
Solar backing 2 temperature setpoint
Allows setting the activation temperature for solar backing 2.
Solar backing 2 activation hysteresis
Hysteresis setting for solar backing 2 activation temperature setpoint.
Minimum value for solar backing 2 temperature setpoint
Lower threshold aimed at preventing an exceedingly low temperature setpoint from being adjusted
inadvertently for solar backing 2.
Maximum value for solar backing 2 temperature setpoint
Upper threshold aimed at preventing an exceedingly high temperature setpoint from being adjusted
inadvertently for solar backing 2.
Solar backing 2 manual activation time
Time for which solar backing 2 stays on when activated manually. After this time solar backing 2 returns
to automatic operation.
Cyclic timer on time
It allows adjusting the time for which the cyclic timer keeps its output on.
Cyclic timer off time
It allows adjusting the time for which the cyclic timer keeps its output off.
Event schedule linking mode
It allows linking the solar backing outputs to one or more of the four daily events. The possible modes
are:
Aux 1 linked to events 1, 2, 3 and 4
Aux 2 linked to events 1, 2, 3, and 4
Aux 1 linked to event 1
Aux 2 linked to events 2, 3, and 4
Minimum S1 temperature alarm
Temperature for sensor 1 low temperature alarm indication
Maximum temperature alarm on S1
Indication temperature of high temperature on sensor 1
S1 temperature indication offset
It allows setting sensor 1 (collectors) temperature indication offset.
S2 temperature indication offset
It allows setting sensor 2 (tanks/swimming pool) temperature indication offset.
S3 temperature indication offset
It allows setting sensor 3 (solar backing systems) temperature indication offset.
.
To disable the temperature sensor for the solar backing systems (sensor 3), access this function in the
advanced function menu. Then press the key
Press SET to confirm.
After sensor 3 is disabled, solar backing 1 and 2 will be controlled by sensor 2 (tank/swimming pool).
If the activation of the water pump is linked to sensor 3 and this sensor is disabled, the controller will
automatically unlink them.
RS-485 network address

4.2.4 - Programming of the events schedule
In this option, you can enter the values for the time periods for each event. The entry of the data depends
on the operating mode configured. You can configure up to four events for each day. For each event, the
start and end time are configured through the options
Start time for the first event
End time for the first event
Start time for the 4º event
End time for the 4º event
If you do not need to use the four events, you can configure it to be deactivated, and all you have to do is
increase the off time (
configure an event to overlap that it begins in one day and it finishes in the other, and for that you should
increase the off time until the option
