I have Fault code F15 / Sensors fault on my heat pump (WPM or Touch screen based). What does this mean?

Fault code F15 / Sensors fault means that the heat pump controller is getting an incorrect reading from one of the temperature sensors on the system.

This fault will require a service engineer or your installer to attend to investigate the issue.
