Step 1
Contact HT-Nova by telephone, by email or through the technical support request form. Include the product model, the serial number and the configuration as far as you have them, an on-site contact, and a description of the malfunction or question - the symptoms, any error message or code, when it started and anything already tried. A photograph of the rating plate, or a short video of an intermittent fault, is usually quicker than describing it.
