4.3. Events schedule operating mode
In this option, you can choose how the events planner will operate.
- Weekly programming
- In this mode, the instrument can configure up to 4 events for every day of
the week.
- Programming for business days
- In this mode, the instrument keeps the events the same for
business days (Monday through Friday), and allows the programming of different events for Saturday
and Sunday.
- Daily programming
- In this mode, the instrument keeps the events the same for all of the days of
the week.
F22 - Solar backing 2 activation hysteresis
Hysteresis setting for solar backing 2 activation temperature setpoint.
F23 - 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.
F24 - 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.
F25 - 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.
F26 - Cyclic timer on time
It allows adjusting the time for which the cyclic timer keeps its output on.
F27 - Cyclic timer off time
It allows adjusting the time for which the cyclic timer keeps its output 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.
F21 - Solar backing 2 temperature setpoint
Allows setting the activation temperature for solar backing 2.

6 -
F28 - Event schedule linking mode
It allows linking the solar backing outputs to one or more of the four daily events. The possible modes
are:
0 -
Aux 1 linked to events 1, 2, 3 and 4
2 -
Aux 1 linked to events 1 and 2
Aux 2 linked to events 1, 2, 3, and 4
Aux 2 linked to events 3 and 4
1 -
Aux 1 linked to event 1
3 -
Aux 1 linked to events 1, 2, and 3
Aux 2 linked to events 2, 3, and 4
Aux 2 linked to event 4
F29 - Minimum S1 temperature alarm
Temperature for sensor 1 low temperature alarm indication
F30 - Maximum temperature alarm on S1
Indication temperature of high temperature on sensor 1
5. SIGNALING
Power LED blinking slowly - Controller configuration corrupted
Power LED blinking rapidly - Temperature sensor disconnected
F34 - RS-485 network address
®
Equipment's network address for communicating with SITRAD software, Wall-Link and Wall-Fi.
Note: one network must not have different equipment with the same address.
To deactivate the temperature sensor of the backups (sensor 3) just set this function to its maximum
value.
If the activation of the water pump is linked to sensor 3 and this sensor is disabled, the controller will
automatically unlink them.
F31 - S1 temperature indication offset
It allows setting sensor 1 (collectors) temperature indication offset.
F32 - S2 temperature indication offset
It allows setting sensor 2 (tanks/swimming pool) temperature indication offset.
F33 - S3 temperature indication offset
It allows setting sensor 3 (solar backing systems) temperature indication offset.
If you do not need to use the four events, you can configure it to be deactivated, and all you have to do
isconfigure the off time (
Off1
for example) with the maximum value. It is also possible to
configure an event to overlap that it begins in one day and it finishes in the other, and for that you should
adjust the off time with the option
Cro
and adjust an event for the next day to start at 00h and 00min.
According to the operating mode configured, the following scheduling possibilities may be presented.

4.4. 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
On1...Off1
up to
On4...Off4
,
where:
On1-
Start time for the first event
Off
1-
End time for the first event
On4 -
Start time for the 4º event
Off4
-
End time for the 4º event
