Frequently Asked Questions - Bandha ASTRALPOOL
How do I install the Bandha temperature controller?
Mount the controller on a wall in a dry location, away from direct sunlight. Connect the power supply (230V AC) and the sensor according to the wiring diagram. Ensure the sensor is placed in the water flow.
What is the operating temperature range of the Bandha?
The controller can measure and display temperatures from 0 °C to 50 °C. It is designed for pool water temperatures typically between 10 °C and 40 °C.
How do I set the desired temperature?
Press the 'Set' button until the setpoint flashes, then use the up/down buttons to adjust. Press 'Set' again to confirm. The controller will maintain the temperature automatically.
What does the alarm code 'E1' mean?
Error code E1 indicates a sensor fault. Check the sensor connection and replace the sensor if necessary. If the problem persists, contact support.
Can I use the Bandha with a heat pump or boiler?
Yes, the controller is compatible with most heat pumps, boilers, and other heating systems. It provides a dry contact output to switch the heating device on/off.
How do I calibrate the temperature reading?
Access calibration mode by holding the 'Set' and 'Down' buttons simultaneously for 5 seconds. Then adjust the offset using the up/down buttons. Typical offset range is ±5 °C.
The display shows 'LL' or 'HH'. What does that mean?
'LL' means the temperature is below -10 °C (low limit), 'HH' means above 70 °C (high limit). Check if the sensor is immersed and not exposed to air. If the issue continues, replace the sensor.
Is the Bandha weatherproof?
The controller has an IP54 rating, meaning it is protected against dust and splashing water. However, it should not be installed in areas subject to direct rain or hose-down.
How to clean the controller?
Use a soft, dry cloth to wipe the surface. Do not use water, solvents, or abrasive cleaners. Avoid getting moisture into the device.
Where can I find replacement parts?
