What to do if I get a HIGH PRESSURE ERROR on my Danfoss DHP-L Heat Pump?
If you receive a HIGH PRESSURE ERROR, it means the high pressure switch has tripped, and the compressor has stopped. To address this, acknowledge the alarm by setting the heat pump to operating mode OFF and then back to the desired operating mode.
Why am I getting a MOTOR ERROR on my Danfoss DHP-L?
A MOTOR ERROR indicates that the overload relay (overcurrent relay) compressor or the overload relay for the outdoor unit fan has been activated. To fix this, acknowledge the alarm by setting the heat pump to operating mode OFF and then back to the desired operating mode.
What to do if the Danfoss Heat Pump shows BRINE OUT error?
The BRINE OUT error indicates that the brine out temperature is less than the set minimum. Consequently, the compressor has stopped. Acknowledge the alarm by setting the heat pump to operating mode OFF and then back to the desired operating mode.
Why does my Danfoss DHP-L Heat Pump display a LOW BRINE FLOW error?
A LOW BRINE FLOW error occurs because the flow sensor was not active during the last start, causing the compressor to stop. To address this, acknowledge the alarm by setting the heat pump to operating mode OFF and then back to the desired operating mode.
What does AUX. HEATER ERROR mean on my Danfoss DHP-L?
An AUX. HEATER ERROR indicates that overheating protection has been activated, and there is no auxiliary heater. To clear this error, acknowledge the alarm by setting the heat pump to operating mode OFF and then back to the desired operating mode.
What happens when the Danfoss Heat Pump shows OUTDOOR SENSOR error?
If you see an OUTDOOR SENSOR error, it means there is a fault in the outside sensor. The control system will use zero degrees when calculating the heat demand. You can acknowledge the alarm by setting the heat pump to operating mode OFF and then back to the desired operating mode.
What does SUPPLY LINE SENSOR error mean for Danfoss DHP-L Heat Pump?
A SUPPLY LINE SENSOR error indicates an issue with the supply line sensor. When this occurs, everything stops except the heating system’s circulation pump. To address this, acknowledge the alarm by setting the heat pump to operating mode OFF and then back to the desired operating mode.
What does FLOW SENSOR error mean on Danfoss DHP-L Heat Pump DHP-C models?
A FLOW SENSOR error indicates that an error has been detected on the flow switch. This applies to DHP-C models. To resolve this, acknowledge the alarm by setting the heat pump to operating mode OFF and then back to the desired operating mode.
