H43Abnormal Zone 1 sensor

Name in the manufacturer's documentation (service manual): Abnormal Zone 1 sensor[1]

In plain words (editorial)

The controller gets an implausible reading from the zone 1 water temperature sensor. Typical causes listed by the manual are a loose connector, a faulty sensor or a faulty indoor sub PCB.

When to call a service technician: Ask the installer to measure the zone 1 sensor and check its wiring (power off first).
