Also, why do you have your maximum flow temperature set to 90 ? Turn it down to a more reasonable maximum ?
When the room is at the right temperature the Evohome sends a heat demand from 1% to the boiler. This 1% is a setpoint from 47 degrees and keeps my boiler on. I would say that when the room is heated up the Evohome should stop sending a setpoint and stop heating. Specially with floor heating because it is a slow system to prevent a temperature overshoot.
A proportional system tries to find exactly the right amount of heat output to equal the heat loss in the room thus maintaining a steady temperature. To maintain a steady temperature there must be a small amount of heat constantly put into the room so if it sending a 1% heat demand to the boiler it looks like it has found this steady equilibrium, thus it is working as designed.
