When already disassembling the machine for cleaning and maintenance, I figure it is also a good time to perform some upgrades. Primarily the aging analog thermostat and pressurestat ought to be replaced with digital PID, but which? I have two options in mind:
- Gicar prosumer PID (Alex Duetto etc.)
- GS/3 AV 3d5 system board
For now, you can totally disregard the difference in cost. Yes, the 3d5 board would be much more expensive, but I actually bought one years ago that I never got around to installing at the time. Also already have a "Piero" group cap (including flowmeter) waiting to be installed, but would need to purchase a compatible display unit. I am also assuming either solution will end up similarly pretty, with 3D printed bezels around any new parts on the front panel.
What is the GS/3's behavior when powered up through the mains switch? Does it go into standby, fully on, or resume the same mode as before it was powered down? My best guess would be standby, which definitely would be a con for me. I have recently started a smart home control project and as part of it have the Linea on a plug that can be powered up or down remotely.
So, given all this information... Which option should I choose?
