C440Prohibit operation condition error (H/P)

Name in the manufacturer's documentation (service manual): Prohibit operation condition error (H/P)[1]

In plain words (editorial)

The unit refuses to run in heating because the operating conditions are outside the permitted range – the service manual says to check the temperature around the outdoor unit.

When to call a service technician: If the code appears in normal weather, contact an authorised Samsung service technician.
