SPLIT is a system for heating, cooling and producing hot water for small houses. The system consists of an outdoor module (L8 SPLIT/L12 SPLIT), which utilises the energy in the outdoor air and sends it to the indoor module (HM 8-12 SPLIT), which takes care of the regulation and heat distribution in the house.

For Home Owners Maintenance Maintenance HM 8-12 SPLIT and L8 SPLIT/L12 SPLIT require minimal VVS 300 SPLIT/VVS 500 SPLIT maintenance after commissioning. SPLIT contains many components and is why monitoring functions are integrated to help you. If something abnormal occurs, a message appears about malfunctions in the form of different ”alarm”...
During the cold months of the year, check to make sure that there isn't a build up of ice or frost under L8 SPLIT/L12 SPLIT. Strong wind combined with heavy snowfall can block the intake and exhaust air grilles.
For Home Owners Dealing with comfort disruption Dealing with comfort disruption Use the following list to find and remedy any heating or hot water problems. Symptom Cause Action Low hot water temperature or a lack of Circuit or main MCB tripped. Check and replace blown fuses.
For Home Owners Dealing with comfort disruption Operating mode "Add. heat only" In the event of malfunctions that cause a low indoor tem- perature, you can normally activate "Add. heat only" in HM 8-12 SPLIT, which means that heating only occurs with the immersion heater.
