Overheating temperature S1 to switch off the pump
Allows configuring the temperature for sensor 1 (panels) to turn the pump off to prevent damages in PVC
piping by not allowing hot water to circulate.
Overheating hysteresis to switch on the pump
Overheating hysteresis to switch on the pump (S2)
Solar backing 1 operating mode
Temperature difference to turn the circulation pump on again.
Example: F11= 80°C and F12= 10°C. The circulation pump will be turned off when sensor 1 reaches
80°C. When the temperature drops and reaches 70°C, the circulation pump is turned on again (80 - 10 =
70).
Overheating temperature S2 to switch off the pump
Required temperature for the swimming pool. It is the value at which the circulation pump will be turned off.
Temperature difference to heat the swimming pool again.
Example:
F13= 28.0 and F14=1.0. This way the swimming pool will be heated until reaching 28°C. After reaching this
value the pump will be turned off. When the temperature drops to 27°C the swimming pool will be heated
again (28 - 1 = 27).
The user can use this function to configure whether the auxiliary systems will be independent from each
other. The modes are:
Solar backing 1 working independently of the support 2
Solar backing 1 deactivated when the solar backing 2 is activated
If programmed to 1, this function allows turning off the gas support system (connected to support 1) and
turning on support 2 (electric heater) automatically. The support systems will never work together.
Solar backing 1 temperature setpoint
Temperature to turn off the solar backing 1.
Solar backing 1 activation hysteresis
Temperature difference to turn on the solar backing 1.
Exemple: F16= 30.0 and F17=1.0
The solar backing turns on at 29º C and turns off at 30º C (30 - 1 = 29)
It should be noted that the first support system is linked to an event schedule (acts in accordance with
user-defined times for up to four daily events). Therefore the times must be programmed for this support to
work properly.
Minimum value for solar backing 1 temperature setpoint
Maximum value for solar backing 1 temperature setpoint
Functions F18 and F19 are only limits to configure F16 (setpoint temperature for support 1). They are used
to block the setpoint if an out-of-range value is wrongly programmed.
Solar backing 1 manual activation time
If the user activates the solar backing 1 manually,
MICROSOL II plus
will count the time configured in
this functions and then return to automatic mode.
Solar backing 2 operating mode
The user can chose the operation mode for solar backing 2.

When the thermostat mode is selected for the water line heating, the supports are controlled by different
sensors. Support 2 is controlled by sensor 3 while support 1 continues to be controlled by sensor 3. For
this, sensor 3 must be enabled in F34. In the other thermostat functions, both supports are controlled by
the same sensor. If sensor 3 is disabled (F34=OFF), both supports are controlled by sensor 2, or else
they are controlled by sensor 3, if it is enabled.
Solar backing 2 temperature setpoint
Temperature desired for the pool (or thermal reservoir), as well as the function F13.
Solar backing 2 activation hysteresis
Temperature difference to turn on the solar backing 2 heating again.
Exemple: F22= 30.0 and F23=1.0
The auxiliary system turns on at 29ºC and turns off at 30ºC (30 - 1 = 29)
This example is valid only if function F21 is configured to 1.

This alarm is visual, shown in the display of
MICROSOL II plus
as the message .
This function allows adjusting (or correcting) any deviation in the reading of sensor 1 caused by an
increase (splice) in the sensor cable or occasional replacement, only if required.
This function allows adjusting (or correcting) any deviation in the reading of sensor 2 caused by an
increase (splice) in the sensor cable or occasional replacement, only if required.
This function allows adjusting (or correcting) any deviation in the reading of sensor 3 caused by an
increase (splice) in the sensor cable or occasional replacement, only if required.
To disable the temperature sensor for the solar backing systems (sensor 3), access this function in the
advanced function menu. Then press the key successively until the message is displayed.
Press 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.

Water pump activation mode
It allows to set the operation mode of the water circulation pump, the options are:
Water pump always OFF
Water pump always ON
Circulation pump operating in automatic mode and not linked to sensor 3.
With this mode the pump is activated only by the temperature differential (S1-S2).

4.2.2 - 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.
4.2.3 - 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 up to , where:
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 ( for example) until the indication appears. 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
increase the off time until the option appears 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.

NOTE:
Should the controller remain off for more than 24 hours, the message will flash on the

this case, simply adjust the controller clock. If this happens, the controller should remain powered on for
10 hours so that the

Cyclic timer off time
Event schedule linking mode
Functions F27 and F28 work when the user configures the solar backing 2 to filter the swimming pool.
Then Microsol will cycle (on time and off time) the filter system.
If function F21 is programmed to 4 or 5, the solar backing 2 will cycle in accordance with the times
programmed in F27 (on time) and F28 (off time).
This function allows the user to configure whether the auxiliary system 2 must work in conjunction with
auxiliary system 1 or not.
If support 2 is programmed as linked to the schedule of support 1 (F21=2 or F21=3), this function will inform
for which events (times) the support systems must be activated.
Minimum value for solar backing 2 temperature setpoint
Maximum value for solar backing 2 temperature setpoint
Functions F24 and F25 are only limits to configure F22 (setpoint temperature for solar backing 2). They are
used to block the setpoint if an out-of-range value is wrongly programmed.
Solar backing 2 manual activation time
If the user activates the support 2 manually,
MICROSOL II plus
