Hi, We have two units where on the first one we used an EVD0000T50 controller – on the following 5 units we used EVD0000T20 – the screen layouts are slightly different and we can’t adjust the PID on the T50s without the controller changing other things.
So we set the T20’s in hot gas bypass and then adjust the PID values to speed the reaction time up.
When we do the same on the T50 the controller changes the configuration back to user defined and off hot gas bypass. Is there something we are missing?
