if you fit an SI model you will prob need a reset code, (not sure if this model comes set for SI or you have to set it) vokera internal SI clocks need to be activated some are activated so you will need to find out, if it is activated it will work fine but at a predetermined time in nearly 12 months the clock will start to flash to indicate a service is due, if an engineer doesn't use the reset code, depending on model the boiler may shut down all together leaving you no heating
All Danfoss SI's are supplied with the SI feature de-activated.
You need to contact Danfoss with proof you are an RGI to obtain the codes.
