Sunvic Controls

My Sunvic select 207 control panel is a fast clicking noise when hot water and central heating are together. Fires the boiler when it is expected, although now, even if the boiler is in hot water not heating, but radiators do if the heater is on. Everything was going well before I goes for six moths, and turn the hot water and central heating. These problems have shown, since I returned. Does anyone know what is the problem? Do I need to buy a new panel or is there another fault?

Relay chatter Defo new panel sorry
