Bosch Greenstar 103 and FW200 supply temp

Hello,
I have a Bosch Greenstar 103 and FW200 controller. Both display the supply temp but they are different. I’ve attached a pic showing the display. Shouldn’t they agree?

looks like the boiler isnt running at this time ( no green light on.)... these temps might get closer when system is running.0

I’ll check when the DHW calls for hot water but I think it’s still different.0

This pic was while the boiler was on -

150* would be the set point , and the unit screen would be the actual temperature . It is a small mass boiler you will get a swing to supply an average .I have enough experience to know , that I dont know it all0
