Why is my Daikin Enfinity CCH not working due to low voltage brownout?
- P
  Phillip GibsonAug 16, 2025
  If your Daikin Heat Pump is experiencing a low voltage brownout, verify that the E terminal is not connected to common. If it is, remove the wire; the LED should then change to solid green only. Also, confirm that the low voltage supply is between 19-32VAC at the H1 terminal of the main board. If the low voltage supply is out of range, verify that the unit supply voltage matches the nameplate voltage and that the correct transformer primary wire has been selected.

What does it mean if my Daikin Enfinity CCH Heat Pump shows 'Low Entering Water Temp'?
- N
  Nicole HunterAug 19, 2025
  If your Daikin Heat Pump shows 'Low Entering Water Temp' (with No Display in Boilerless EH), it indicates a low entering water temperature, specifically below 35°F in the standard range or 13.5°F in the extended range.

What to do if my Daikin Heat Pump has compressor high pressure?
- T
  Timothy ThompsonAug 22, 2025
  If your Daikin Heat Pump is showing compressor high pressure, verify the high pressure switch is connected to terminal H3 on the main board. Also, check the continuity of the high pressure switch. Make sure to check the water flow if it’s in cooling operation, or check the airflow if it’s in heating operation. Finally, ensure that the entering water and air temperatures are within the operating limits.

What causes a Daikin Enfinity CCH to have compressor low pressure?
- D
  Debra MillsAug 26, 2025
  A Daikin Heat Pump may experience compressor low pressure due to a loose wire connection on the low pressure circuit, a failed low pressure switch, or the unit being low on charge. Check these components to resolve the issue.

What to do if my Daikin Enfinity CCH Heat Pump displays 'Compressor Suction Temp Sensor Fail'?
- F
  Frank SnyderAug 31, 2025
  If your Daikin Heat Pump displays 'Compressor Suction Temp Sensor Fail,' check the connection of the low suction temperature sensor on terminal H6 pins 2 and 3. Also, check the resistance of the low suction temperature sensor, leaving water temperature sensor, and room sensor or return air sensor; all sensors should measure 10kohm thermistor @77°F. Ensure that the return air sensor and room sensor are not connected simultaneously.

Why does my Daikin Enfinity CCH show 'Unoccupied Mode'?
- R
  Randy AguilarSep 3, 2025
  Your Daikin Heat Pump might show 'Unoccupied Mode' because terminal U on the main control board is connected to common from an external source, or the network is overriding the occupancy mode.

What does it mean when my Daikin Heat Pump is in 'Occupied, Bypass Mode, Standby or Tenant Override Modes'?
- J
  Jackie DillonSep 6, 2025
  When your Daikin Heat Pump is in 'Occupied, Bypass Mode, Standby, or Tenant Override Modes,' it means the unit is operating normally. It may currently have a control signal or be ready to operate when a control signal is active.

What causes 'Condensate Overflow' in my Daikin Enfinity CCH?
- C
  Catherine BeasleySep 8, 2025
  A 'Condensate Overflow' in your Daikin Heat Pump (in Cooling & Dehumidification Modes Only) is caused by poor condensate drain. Check the resistance to ground on the condensate wire; it should be open if there is no water in the pan.

What does it mean if my Daikin Heat Pump displays 'Service Test Mode Enabled'?
- K
  Kenneth BrandtSep 12, 2025
  If your Daikin Heat Pump displays 'Service Test Mode Enabled,' it means that jumper JP1 is shorted for service test mode operation. Note that this mode is used only for testing purposes, and control timing may damage actual hardware.
