Error Code: EH 60 – Indoor Room Temperature Sensor (T1) Error

Error Code: EH 60 – Indoor Room Temperature Sensor (T1) Error
Applies to LETO and AURA Series

What this means:
The T1 sensor, which reads the room temperature, is either shorted, disconnected, or giving incorrect readings. This sensor helps the unit adjust its heating or cooling output based on the room temperature.

Try this first (easy fix):

1. Turn off power to your mini split completely.

2. Wait 2 full minutes.

3. Turn the power back on and check the display.

• If the error disappears — the issue may have been temporary.

• If the error remains — continue with the steps below.

Next steps (for technicians):

• Check the wiring between the T1 sensor and the indoor PCB.

• Ensure the connections are secure and not corroded or damaged.

• Measure the resistance of the sensor:

  • If resistance is out of range, replace the sensor.

  • If resistance is normal but the error persists, the indoor PCB may need to be replaced.

What you might need:

• T1 room temperature sensor

• Indoor PCB

• Connection wires

Helpful tip:
This error typically occurs when the sensor voltage is below 0.06V or above 4.94V. Always measure the sensor before replacing the board. The T1 sensor is a key component for automatic temperature regulation.
