Hello,
Could you please share the config software again.
GC-1201STool-V2.0-PW1234.7z
It seems like the link does not work any more.
Thx
hmm, the link seems to still work for me, in any case i reuploaded it for you on a different site GC-1201STool-V2.0-PW1234
Hi guys, back again. My setup seems to be working fine with my yaml config. In my area we often get power outages in bad weather conditions and the only issue I’m having is in case of power outage the heat pump shows E00 and unless I disconnect my waveshare module, reconnect the original Hi-T controller, wait for Hi-T software boot and error reset on heatpump, then disconnect controller and reconnect waveshare module the error will not reset. I event tried to setup various automations to set the control registers and change their status, but nothing seems to work unless I do the procedure I just described. Since I’m not interested in my original Hi-T controller what can I do to prevent this from happening? have you also experienced the same issue?
I’m not sure i understand your problem. E00 is not an actual error. it just means that the heatpump is off and waiting for an external device to turn it on by closing the x15 contact
Yes, I realised my mistake this afternoon analysing the heat pump’s manual, I’ve now put a jumper between x15.1 and x15.2 which solved my problem and enabled remote control. Didn’t need it with the original controller because it closed it digitally. Also created an automation to detect when register 7201 is 0 to automatically restore it to 3 so that in case of power outage it restores control automatically.
Thanks!
@ProtoxiDe22 Thank you so much for your tutorial and all your advice and details. I managed to configure everything on Home Assistant and it works like a charm.
I have a 16kW single-phase Maxa i-32v5 and an e-pro controller at home.
Perhaps you could add a step to your tutorial explaining what material to use and how to connect to the GC1201s bridge, because when you receive it, it doesn’t work with the factory settings.
You need to connect using a USB-RS 485 converter to change the “parity” parameter.
yeah that’s true, i posted the settiings to be used, but didn’t get into the nitty gritty of how you actually do that, referring to the manual for that.
By the time i made this post, it had been a couple weeks since i configured the bridge, so i forgot. i’m not able to make a detailed guide (if you want to write that part i can add it tho!) but in the meantime i added a note about the need for the usb adapter in the original post
Currently the heat pump is controlled by the e-pro controller with a climate curve setting.
But in some moments I wish HA could manage it manually (for example when I have a lot of photovoltaic production) and I have the impression that if I change the temperature in Heating Setpoint it doesn’t matter.
Do I need to activate Remote Setpoint Writr Enable? And if by chance I manually change the temperature of Seth Point from HA, how can I then get the climate curve back into operation?
i have no idea since I never used a climate curve setting, but yes, you would need to enable remote setpoint writing to override setpoints via ha
Hi, first of all, I should say that I’m still trying to figure out how to connect everything. I’d like to connect Home Assistant to the same terminal block where the original controller is also connected, passing through the GC-1201S first, but I noticed that besides the A and B terminals and the power supply terminals, there is also a GNDR terminal that acts as a signal reference. Can this simply be ignored?
