3. Check the improvement in comfort over one week.
4. Readjust the parameters as needed.
Silent mode is used to reduce the noise level of the outdoor unit during
specified programmed hours. This mode limits the performance of the heat
pump.
1. Activate silent mode.
2. Program the operating range in silent mode.
The multifunctional output X19 for the EHC-14 PCB sends an on/off signal
(dry contact) based on the status of the Cooling mode, Defrosting mode or
Silent Mode.
1. Follow the access path described below.
Adjustment required
