Currently, there is one fault pending. Contact a specialist company.

Number of lines = error number. The figure shows error number 3.

Active unit errors are also displayed during standby mode.

When a fan fault (supply air/exhaust air fan) is remedied, correct fault rectification must be acknowledged manually.

If the T exhaust air too cold/T supply air too cold fault occurs, acknowledge the fault message manually and wait about 10 minutes. A temporary temperature sensor fault disappears automatically. If it doesn’t, contact a specialist installer.
