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?
The EVD0000T50 and T20 are identical in terms of screens and software and functionalities.
The only variant is that the T20 is open to control also Alco, Sporlan and Danfoss valves, whilst the T50 is only for Carel Valves.
You should find everything exactly the same... Unless you are viewing the User menu rather than the Manufacturing menu. This depends on the password you have used to log-in.
Service password is: 22
Manufacturing password is: 66
If you log in with the Service password you will be restricted to view only specific parameters.
Hope the above is the simple reason why you are not viewing the parameters you are expecting to see.
