Frequently Asked Questions - WH-SDC16H9E8 PANASONIC

How to reset the remote control lock password?

To reset the forgotten password, set the unit to STOP mode, then simultaneously press the ↩ (return), ← (select), and ▶ (right arrow) keys for 5 seconds. The screen will display 'Initialize password'. Select Reset to reset the code to 0000.

What to do if the error 'Forced DHW backup is disabled' appears?

This error can occur when forced heating is enabled. First disable Forced heating from the quick menu, then re-enable Forced DHW backup if necessary. Also ensure that the tank connection is enabled in the settings.

How to program the heat pump for weekly operation?

Access the quick menu and select the Weekly prog icon. Press ← to confirm. You can then program up to 6 time slots per day, setting the time, mode (heating/cooling) and temperatures for each zone. Use the ▲▼ keys to navigate and ◀▶ to modify.

Is silent mode available and how to activate it?

Yes, silent mode is available in the quick menu. Select the Silent mode icon and press ← to activate. You can choose from 3 silence levels (level 3 being the quietest). The mode starts approximately 1 minute after activation.

How to force backup heating (electric resistance)?

In the quick menu, select the Forced backup heating icon and press ←. The mode activates after about 1 minute. Note that it automatically disables if the system is in normal operation. To cancel, reselect the icon.

What is the procedure for manually defrosting the outdoor unit?

Use the quick menu and select the Forced defrost icon. Confirm with ←. The screen will display 'Request accepted'. The defrosting is performed automatically and may take a few minutes.

How to reset error codes after a fault?

In the quick menu, choose Error code reset and validate with ←. Ensure all units are stopped before proceeding. The screen will display 'Request accepted' and the error codes will be cleared.

Can I use the heat pump without a domestic hot water tank?

Yes, but some functions (like Forced DHW backup) will not be available. Make sure to disable the tank connection in the system settings. The quick menu will then display without the DHW-related options.

What does the 'Remote lock' icon mean and how to use it?

The remote control lock (R/C) prevents unauthorized changes. To activate, select Remote lock in the quick menu and confirm. To unlock, press any key, then enter the 4-digit PIN code (default 0000).

How to clean the indoor unit filters?

Turn off the unit and unplug the power. Open the front panel and gently remove the filters. Wash them with warm water and mild detergent, rinse, and dry completely before reinstalling. Perform this operation every 1 to 3 months depending on usage.
