Hello @maurice
Thanks again for you detailed feedback
Programming Offline
After successful installing the T3000 in my documents directory on my laptop, I begun to try coding a sub program .
In the online programming guide the declare and call statement are explained but with a remark saying not implemented…this is what made me confusing.
When I put a DECLARE statement in the program, it is well identified by the syntax checking so I thought first that the documentation was not up to date.
If it is a question of month to have this, I can wait a little, only using a Nano with a PT12 in the beginning to replace my bad pt1000 modules
I was also surprised to see in the release text file in the T3000 directory that the last documented release was from 2016.
I will thus order a Nano… and a PT12
I understand that I can run in a Nano a full software and test it without any Real IO connected. Am I wright?
Can I also configure trends, schedule, graphics to test and evaluate the logic?
Triac module are needed because my existing control works with a PWM on a 120 s cycle base for controlling some 240 V actuators.
I am not sure it is a good idea to do the same with the mechanical relay supplied with boiler controller.
Regarding this relays of the boiler controller, are they monitored by the controller on a digital input in order to check they open and close properly?
What about boiler controller coding, shedule and graphics facility? Are they the same as the T3 Nano or BB? Do they accept also external Expansion IO like PT12 or Metz connect?
If would use two or three boiler controllers and having a PT12 module in another place on the same network, can both boiler controller access the same measurement ? How to share measurement between two controller?
