5.2 - Functions
Shortcut to adjust the parameter F13
This shortcut is used when the Microsol II plus is installed to control swimming polls heating systems. In
this case the parameter F13 adjusts the maximum confort temperature of the pool water.
Shortcut to adjust the parameter F16
Allows the facilitated adjust of the solar backing 1 temperature setpoint.
Sho tcut to adjust the parameter F22 r
Allows the facilitated adjust of the solar backing 2 temperature setpoint.
Water pump start
It allows to set the operation mode of the water circulation pump, as follows:
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).
Circulation pump operating in automatic mode and linked to sensor 3. With this mode the
pump is activated by the temperature differential and when the temperature at sensor 1 is higher
than that at sensor 3.
Manual activation of solar backing 1
With this option the output of solar backing 1 is manually activated. The output is deactivated after the time
adjusted in function expires. Upon entering this function again, the manual activation is overridden
and the solar backing 1 returns to automatic operation.
To disable the manual activation just configure the function
Manual activation of solar backing 2
With this option the output of solar backing 2 is manually activated. The output is deactivated after the time
adjusted in function expires. Upon entering this function again, the manual activation is overridden
and the solar backing 2 returns to automatic operation.
To disable the manual activation just configure the function
6. QUICK VIEW
6.1 - View other temperatures
To switch between the temperature views for sensor 1, sensor 2, sensor 3 or temperature difference
between sensors 1 and 2 (differential temperature), press
Sensor 1 temperature
Sensor 2 temperature
Sensor 3 temperature
Differential temperature (S1-S2)
The selected temperature will be displayed for 15 seconds and then the default indication returns (as per
parameter setting).
6.2 - Visualize the current time
Quickly pressing the key , you can visualize the time set in the controller, the current time will be

6.3 - View maximum and minimum temperatures
Pressing the key enables viewing the maximum and minimum temperature for each sensor, as well
as the maximum and minimum temperature differentials. Upon pressing the key
message will be displayed to indicate sensor 1 temperature and then its maximum and minimum
temperatures will be displayed, then the temperatures for sensor 2 (
differential ( ) will be displayed in sequence.
If the key is pressed during the visualization, the values will be reset and the message
displayed.
7. SIGNALING
Sensor 1 (collectors) disconnected or out of range
Sensor 2 (reservoir /pool) disconnected or out of range
Sensor 3 (solar backings) disconnected or out of range
Error in the differential temperature calculation
Temperature for sensor 1 is freezing
Temperature for sensor 1 is overheated
Temperature for sensor 2 is overheated
Configuration parameters not programmed or out of range
Circulation pump in off manual mode
Circulation pump in on manual mode
Sensor 1 high temperature alarm
Sensor 1 low temperature alarm
Solar backing 2 activation alarm
8. UNIT SELECTION (°C / °F)
To define the unit that the system will use to operate, enter into the functions menu
access code "231" and confirm it by hitting key

Used to connect more than one instrument to the Interface. The wire's connections must
be made in agreement with the following rules: terminal of the instrument connects to

The terminal of distribution box must be connected to the respective terminals
each instrument.
IMPORTANT
According to the chapters of norm IEC 60364:
1: Install protector against overvoltage
2: Sensor cables and signal cables of the computer may be joined, but not in the same electric conduit
through which the electric input and the activation of the loads run.
3: Install transient suppresors (RC filters) parallel to the loads as to increase the product life of the
relays.

PROTECTIVE VINYL:
This adhesive vinyl (included inside the packing) protects the instruments against
water drippings, as in commercial refrigerators, for example.
Do the application after finishing the electrical connections.
Remove the protective paper
