How to reduce noise levels from my Bosch SV060?
- J
  Justin HarrisAug 17, 2025
  To reduce objectionable noise levels from your Bosch Heat Pump, consider the following: Ensure the duct work and grilles are properly sized for the unit's air flow. If the fan speed is too high, consult the blower performance table and reduce it if possible. Make sure the unit is mounted on a full vibration pad. Ensure the unit is installed correctly and adjust the unit location to prevent it from touching the structure.

Why is my Bosch SV060 compressor so noisy?
- C
  Cheryl ShepherdAug 20, 2025
  If your Bosch Heat Pump compressor is noisy, it could be due to high water temperature or low water flow rate, which elevates the head pressure. If possible, increase the water flow rate and/or reduce the water temperature. Another cause could be a scaled or fouled water coil, which also elevates the heat pressure; in this case, clean/descale the water coil. Low air flow can also cause compressor noise, so check the filter and increase fan speed.

Why is the fan not working on my Bosch SV060 Heat Pump with a constant airflow motor?
- J
  Joyce GutierrezAug 22, 2025
  If the fan on your Bosch Heat Pump with a constant airflow motor isn't working, check the following: Ensure there's a fan operation signal by checking for 24 VAC between "G" and "C", and verify all wiring connections, including the thermostat connection plug. Inspect for loose wiring at the motor and control box, ensuring power and control harnesses are securely connected. Examine the interface board for damage and ensure all DIP switches are in the correct configuration. Finally, check the supply voltage to the motor, ensure all motor wires are secure, and test the motor by moving the "TEST" DIP switch to "ON" and the other switches to "OFF" on the "ADJUST" switch block on the interface board.

What to check if the fan isn't working on my Bosch SV060 Heat Pump with a constant torque motor?

  liukevinAug 26, 2025
  If the fan isn't working on your Bosch Heat Pump with a constant torque motor, first check for a fan operation signal by ensuring there is 24 VAC between "G" and "C", and check all wiring connections. Also, inspect for loose wiring at both the motor and the control box. Finally, check the supply voltage to the motor, make sure all motor wires are secure, and with the power off, spin the motor shaft to check for noise, resistance, or uneven motion, which could indicate motor failure.

How do I troubleshoot a Bosch Heat Pump fan that isn't working (PSC motor)?
- W
  William GreerAug 27, 2025
  To troubleshoot a Bosch Heat Pump fan that isn't working and uses a PSC motor, start by checking the supply voltage from the fan relay to the motor and ensure all motor wires are secure. Next, check for a fan operation signal by verifying 24 VAC across the fan relay coil and inspecting all wiring connections. If the relay coil is energized but the relay doesn't pull in, check the resistance across the relay coil, as an open circuit indicates a faulty relay. With the power off, spin the motor shaft to check for noise, resistance, or uneven motion, which can indicate motor failure.

Why is there high humidity with my Bosch SV060?
- M
  Martin LopezAug 30, 2025
  High humidity with your Bosch Heat Pump may be due to several reasons. The fan speed setting might be too high, so consult the blower performance table and reduce the fan speed if possible. There could be low refrigerant levels, so check the refrigerant pressures with a gauge set. The unit might be oversized for the space, so check the unit performance against building load calculations. Also, the thermostat might be poorly located, such as near a supply air duct; relocate it if necessary.

What to do if my Bosch Heat Pump has excessively warm air in cooling or cool air in heating?
- S
  Susan McdonaldSep 1, 2025
  If your Bosch Heat Pump is producing excessively warm air during cooling or excessively cool air during heating, several factors could be responsible. The fan speed setting may be too high; if so, consult the blower performance table and reduce the fan speed if possible. The inlet water temperature may be out of range; check the unit capacity versus the water temperature. Leaky duct work could also be a factor, so inspect the duct work. Finally, low refrigerant levels can cause this issue, so check the refrigerant pressures with a gauge set.

Why is my Bosch SV060 blowing excessively cold air in cooling or hot air in heating?
- A
  Andrea HernandezSep 4, 2025
  If your Bosch Heat Pump is blowing excessively cold air in cooling mode or excessively hot air in heating mode, start by replacing the dirty filter. Also, the fan speed might be too low; consult the blower performance table and increase the fan speed if possible. Lastly, excessive duct pressure drop could be the issue; consult the blower performance table and increase the fan speed if possible to compensate.

Why won't my Bosch SV060 Heat Pump switch to cooling mode?
- L
  Laura HesterSep 9, 2025
  If your Bosch Heat Pump isn't shifting into cooling mode, there are a few things you can check. First, see if the reversing valve solenoid is receiving 24 VAC; if it is, check the solenoid's resistance, as an open circuit may indicate a burned-out solenoid. Next, check that the reversing valve thermostat wire is connected to the "O" terminal of the thermostat and that there's a contact closure between "O" and "R". Lastly, make sure the wires from the thermostat to the unit and from the electrical box to the reversing valve are securely connected.

What to do if my Bosch Heat Pump compressor and fan aren't working?
- A
  alyssa53Sep 12, 2025
  If neither the compressor nor the fan is operating on your Bosch Heat Pump, first ensure that the supply voltage to the unit is within the range shown on the unit data plate. Then, check for 24 VAC between "R" and "C" on the unit terminal block to verify the control transformer is functioning. For 75 and 100 VA transformers, check that the transformer circuit breaker has not tripped. Before replacing the transformer, check the low voltage circuit for overload conditions or short circuits.
