I have installed a Heatline Monza 24 Combi which appears to be working correctly on the DHW mode. However when CH is called for the boiler fires up until the temp reading on the boiler reaches 65 degrees. The boiler then shuts off until the displayed temp drops to around 45 degrees. This cycle then continues. The pressure is currently showing 2 bar. There are no fault codes displayed. I have checked the CH parameter within the boiler settings and it is set at 78 degrees.
