Anyone in here knowledgeable on mechanical heat recovery ventilation systems?

I have a Paul Novus 300

When I look at the wall mounted controller it says
Outside air: 6.5°C
Supply air 11.5°C

When I check the temperature coming out of the ducting in the bedrooms is about 16°C

I was expecting the supply air to be quite a bit higher considering the whole house is set between 22-23°C.

There is also an issue of a 'summer bypass blocked' message coming up - Spoke to Paul themselves and they said I would need to buy a new circuit board but if i was happy I can just set the system to disable the bypass and the controller does say it is closed.
