To test the sensor - heat it with hair dryer - with the heating set to 25 degrees - the flow temperature should fall significantly.
The room influence setting should have been determined and set by your installer. The setting is to adjust the impact ( positive or negative ) of the precise positioning of the external sensor against the pre programmed temperature curves in the boiler software.
What you are aiming to achieve is to maximise the duration that the boiler is condensing ( ie. return flow below 55degrees C ) Obviously that is not the case on very cold days - where the driver is to maximise the flow temperature, whilst keeping the temperature delta across the heat exchanger to around 15 degrees C - I think, unless my memory fails me.
If you cannot reengage your installer, set the influence setting to 1. Stop tinkering and leave the system to operate. Observe how it behaves, then after a few weeks make any required adjustments and repeat the process again.
Constant adjustment of the system settings is unlikely to deliver an effective result.
Try to understand over time how the complete system behaves - optimisation ( if applicable), boiler modulation and external temperature flow temp compensation
Any questions get back to me
