Enable cooling on VRC700 #438
Comments
Same problem here - haven't found the right codes at the moment. |
I would like to see this option too. For some reason my VRC700 doesn't switch my heatpump to cooling automatically (although it should based on what Vaillant technician told me), I have to enable it manually, but this change is not reflected on any of those commands. |
No news here, but I will ask my Vaillant technician again about the option of switching to cooling automatically. Although I don't expect to use it in the short term with the Belgian summer we had. 😢 I'll post here if I know more. |
Thanks for the update. Yea it was the same with summer here in Czech republic, but we had like two weeks of hot weather and it would be nice to have this option to enable the cooling remotely before we returned from the vacation. I didn't make any progress so far, I see some undecoded values coming from the heatpump itself but I can't seem to find any sense in them. |
Here in Spain this is an issue... Regards |
Right, I couldn't get it to work in auto mode, it didn't star the whole summer and we had quite a lot of hot days. I always had to turn it on manually. Even called Vaillant about it, and they basically said the same as you and couldn't help further. |
Regarding how it works - as I have observed it: For starting the cooling mode, this averaged outside temperature AND the actual outside temp have to be higher than the cooling starting temperature parameter in the configuration (in my case 23°C). What I have observed in addition is, that the averaging is reset if you power-cycle the heatpump. Meaning, directly after the power cycle the average temp. equals the actual outside temp. My this helps a little bit. |
I've been using ebusd for almost a year with a Saunier Duval rebranded arotherm split 8 + VRC720. I am about to set everything up again, because I have a defective microsd in my EBUS RPi and also made an absolute mess setting things up a year ago. @nafgarda Do you own a Vaillant or a Saunier Duval unit? |
I've got Vaillant. My zones are not controlled by Vaillant, so that is the plan. I have 9 analog thermostat and 11 zones controlled with 11 solenoids. My plan is to replace the analog thermostats with Shelly wifi relays equipped with a thermocouple. At first I would use the Shelly cloud interface to set up the desired temperatures and it scheduling. My solenoids have a dry contact circuit that tells if they are open or close. That circuit from all solenoids is already connected to the heat pump and when all the solenoids are close, the heating stops automatically. I'm planning to use as well ebusd with Node Red installed in the same RPI:
Total aprox budget: That's all I think. |
I am only interested in pushing hot water control commands through ebus, as I don't have any other thermostat different from the remote control unit. I turn the fancoils on and off using plugs (the fancoil units remember their last state). |
please discuss in the right area (e.g. https://github.com/john30/ebusd-configuration/issues/), not here as this repo is for the source code of ebusd and not for configurations |
Quick question:
I'm trying to get cooling to work on my VRC700 via ebusd, but I cannot find the right commands. So I'm trying to put my heat pump system in cooling mode, either trough the main settings, or as manually cooling (setting for a number of days.)
Can somebody point me in the right direction?
