6 Special Functions:
6.1 Pump exercise function:
If pumps are not activated for a period of 48 hours, this function will automatically
activate them for 15 seconds to avoid jams.
6.2 Dimmer function:
To save power, the backlight automatically dims if there is no keypad activity for a
period of 10 minutes.
6.3 Security function:
To avoid unintentional/unauthorized changes, System type and Extra Function
selection ( No , Thermostat , Cooling , or Diffcontrol ) are inaccessible after the

If you want to modify these parameters at any time past the 15 minute settings lock,
you must disconnect and reconnect the power to the controller.
•
This action will not reset the control; it will only allow access to make
modifications.
To reset all of the control settings to the factory default values, see

7 Ohm to °F Conversion Chart for PT1000 Sensors:
Sensor temperature can be read with an Ohmmeter as a preliminary troubleshooting
measure by the following method:
Perform this test only after disconnecting the sensor.
•
Disconnect the sensor leads from the solar control.
•
Connect the leads to an Ohmmeter.
•
Use the following chart to determine the approximate temperature at the
sensor bulb.
