Faran HR15 and H50 Error codes

The most common error code that comes up is ER3

  • Er3 = Humidity sensor short-circuit

If you have the error code ‘ER3’ appear in the humidity display it means that it’s over 99% humidity, it is too wet.

When the sensor is wet, it could be that you have it set too high, or there must be a bit more humidity lately and your current setting needs adjusting because it is overrunning. When you get extra humid weather it can make it go much higher with humid air coming into the room from outside.

When this happens, turn your setting down a few % lower and it should dry out and start reading correctly again.

 

Other error codes that can come up include:

Er0 = Error in memory – Turn off the power and reset.

Er1 = Temperature sensor short-circuit – This means that your room is too hot.

Er2 = Temperature sensor disconnection – This means you have a damaged sensor cable.

Er4 = Humidity sensor disconnection – This means you have a damaged sensor cable.
