Circulation pump operating in automatic mode without sensor 3 temperature validation. In this
mode the circulation pump will be activated only by the diferential of temperature (S1-S2)
Circulation pump operating in automatic mode with sensor 3 temperature validation. In this
mode the circulation pump will be activated by the diferential of temperature (S1-S2) and
when the temperature at sensor 1 is bigger than at sensor 3.
Confirm the selection by pressing key SET
the function.
5.7 - Disabling the temperature sensor 3
To disable the solar backing`s temperature sensor (sensor 3) enter the functions menu and access
function .After entering the function press the
display, press the SET key to confirm and exit.
When the sensor 3 is disabled the solar backings 1 and 2 will be controlled by sensor 2 (reservoir/pool).
If the circulation pump is adjusted for operation with sensor 3 validation and the sensor 3 was
deactivated the controller will automatically disable the validation.
6. 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
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
7. 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
to choose between: or and confirm with key
message will appear, and the instrument will return to the function
the parameters should be reconfigured, since they assume "standard" values.

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.
For more information, please contact our Technical Support by e-mail:
phone +55 51 3475.3308.

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
and apply the vinyl on the entire
superior part of the device,
folding the flaps as indicated by
the arrows.
