Most common faults are caused by problems with the WiFi signal. Please verify that you have good WiFi signal at the heat pump location using your mobile. Try to relocate H66 and keep it away from metal and cables. In worst case you may have to buy a WiFi extender unit to amplify the signal.

For stable connections, make sure you have created a dedicated WiFi network using 2.4Ghz for the H66.
For some WiFi equipment brands (often UniFi) , H66 can behave unstable if not having a dedicated network. Also there are some settings for UniFi you can test to set “802.11 DTIM Period” from Auto to 3.

_____________    Fixed light: Initializing heatpump (short period at first start)

Initialisation should not take more than one minute

Trouble Green LED status

By verifying the start sequence described above you can find out if the H60 get stuck on some initialisation step.

Please always verify that you have good Wi-Fi signal the location.

Repeat the Installation procedure and verify that you have given the right Wi-Fi credentials (SSID and password). See “factory reset” below on how to restart the wifi-setup procedure.

Check connections to heat pump. Go through the installation manual for your heat pump again.

If you cannot get WiFi working you should examine the H60 log for more info. Enter H60 web interface by holding the INIT button for 1 sec (until green start flashing). Then enter the device web page using the same procedure as during installation. Scroll down on then page and select “advanced settings”, Click on LOG to examine reason for problem.

Red led

Irregular flashing is normal when communicating with heat pump.

Dark, fixed light or repeating fast-blink-dark, fast-blink-dark indicate something is wrong. However the led can have a fixed light for short periods while initializing.

Forgotten password

If you have forgotten the password for the weblogin you could either do a factory reset or connect the unit to your computer using an USB cable. Disconnect from heat pump first. See Advanced section for further instructions.

Factory reset.

If you like to start over from beginning, hold the Init button for 8 seconds and H60 will load factory default values.

Troubleshooting using Email and H60 web portal

If you entered your email address at the installation, H60 will send you a mail every time it starts up. The email can of course only be sent if the Wi-Fi connection is working properly.

The mail contains a link to the local H60 web portal for additional configuration and troubleshooting.

When accessing the H60 web portal you can view error messages in the LOG menu. Using the SUPPORT page you can send a ticket to Husdata for further assistance.
