Vigas 40L CPU T3 Error

[Jcc583]

I’m hoping someone can help me I have installed a Vigas 40L with an ak3000 CPU. The flue temp is read by a pt1000. I’m getting CPU T3 error. What type of sensor or thermostat is needed for the thermal storage T3 connection?

Someone please! Lol

The AK3000 would indicate an older boiler, I assume this is not new? Based on my manual (AK4000) the T3 error refers to a indoor thermostat signal. “Indoor thermostat signal disturbance caused by induction of simultaneous power supply.” This nothing that I have ever seen but based on the post I thought I’d report what my manual said. Good luck, I’ve been running my Vigas40 LC for about six years and very pleased with it.

Have you tried calling Mark? He has always been super responsive to me. I have the same unit. Are you asking what you need to determine temp of your storage?

Yes I called and left a voicemail and I sent an email. I’ve tried all temp sensors, KTY and PT1000 with no luck. I did a simple jumper with no luck! I also wired directly to the board with no change. I’m stumped!

Yes what type of sensor is used.

Better picture of error. Thanks in advance for the help!

I don't know what it's called exactly but it wires into the area on the back of the unit you have a picture of. Other end goes into a drywell on your storage.

So - you have tried a PT1000 sensor, and it didn't work?

Yes, Vigas uses a very precise resistance sensor that can’t be read using other PTS. Thanks everyone!

So did you get it working? If so it might be helpful for others in the future if you posted an exact fix .
