To Next PageTo Next PageWhat to do if the thermostatic control valve does not close on Danfoss Termix AT BTD?
If the thermostatic control valve on your Danfoss Boiler does not close, the temperature difference between the DH supply and the DHW set point might be too low. Try lowering the set point temperature or increasing the DH supply temperature.
How to troubleshoot too little or no DHW in Danfoss Termix AT BTD Boiler?
If you're experiencing too little or no domestic hot water (DHW) with your Danfoss Boiler, several factors could be responsible. Start by checking for a clogged strainer in the supply or return line and clean it. Ensure the DHW circulation pump is working correctly and set appropriately. A defective or clogged non-return valve can also cause issues, so replace or clean it. Confirm that there is electricity supplied to the boiler. If automatic controls are in place, verify their settings. Scaling of the plate heat exchanger may be the cause, requiring replacement or rinsing. Check the motorized valve, temperature sensors, and controller for defects, replacing as needed.
Why is there a temperature drop during tapping in my Danfoss Boiler?
A temperature drop during tapping with your Danfoss Boiler may be due to scaling of the plate heat exchanger, in which case you should replace or rinse it out. Alternatively, the DHW flow might be larger than the substation was designed for, so try reducing the DHW flow.
