10.5 Calibrating temperature sensors

Note: Usually, there are no settings to be done in this menu as

the device is adjusted to sensors Pt1000 and operates with

degree-accuracy.

However, long sensor cables or bad placement of the sensor

can lead to distortion of the measurements which can be balanced

via adjustments in this menu.

Offset S1...S3

The three sensors can be adjusted one after the other. Each

step corresponds to a change of the measurement of approx. 1/

3 °C upwards (+) or downwards(-).

Setting range:-20...+20 Default value: 0

11. Changing the operating mode

Here the operating mode of the controller can be changed

between automatic, off or manual operation. Caution: In the off

or manual operation, there is no normal control process and also

functions like solar and freeze protection as well as storage

temperature limit etc. are not in operation and the red LED flashes

to warn. After quitting the off or manual operation, the controller

returns in back to the automatic mode on its own.

Only the specialist is allowed to activate the manual operation

for control or adjustment works. The manual operation must be

quit after finishing the work for the controller to return back to the

automatic operation.

In the manual operation, relay R1 / R2 is selected via the Plus or

Minus key and is switched on / off via the Enter key.

The controller returns back to the automatic operation via the

option „Esc“ and by using the Enter key.

12. Displaying temp. values and measurements

The desired values are displayed via the Plus or Minus key and

the menu can be quit again via the Enter key.

At first, the current temperatures at sensors S1-S3 are displayed.

Afterwards, the current rotational speed stage of the solar pump

is proportionally displayed. The total running hours of the solar

pump (the relay) can be read under the displayed value „Running

hours R1“ and „Running hours R2“.

If one of the sensors is defect which is necessary for the control

function, the red LED flashes and the temperature value <-40°C

in case of a bypass or >230°C in case of an interruption is

displayed.

13. Query of service values

In case of obscurities with the control system and of errors, the

diagnosis values, which can be called up here, must be written

down at the moment of the error. Afterwards, these data can be

used e.g. for a telediagnosis by phone. The different values one

after the other are displayed by using the Plus key. The menu will

be quit via the Enter key.
