Hello everybody, Fabio from Italy here.
We have just finished the installation of a Vitocal 150-A modular + puffer 6 connections 300lt for heating and cooling a house with fan coils. There was already a Vitodens 200 (gas) installed in the 2012, with two stations: the fan coil one mentioned above and a floor panels one. In the future we could end up having to add a ceiling panels new station.
I managed to read and download some of the diagnostic values of the system through python scripts via the API and then dump the values in a csv file. With an Excel workbook I import the values from the csv and show them on a grafic to monitor (and learn) how the various temperatures moves and the pumps and compressor switch on and off when the system in on.
For example, here you can see the monitoring of today time from 12:16 to 18:14.
(due to the limitations of the API calls I can only monitor about 6 hours as I'm asking for 10 different values every 2 minutes)
The only temperature I couldn't read is the return from the fan coils line, to check how much thermal exchange I'm having, to see if it's already optimal or if I can improve it, maybe slowing up or down the fan speed or, if it will be possible, modify the flow rate of the pump.
The system seems not to have a specific input for such a temp sensor but maybe you know better than me and my engineer and will tell me thet it's there...
Thinking it is not, and to the fact that an EM-HB1 module was installed to enable/disable the old Vitodens 200 (old bus protocol), I'd like to ask if would it be possible to use the TS2 sensor port on the EM-HB1 that by now has an NTC sensor wired to but it's not in use. Could I use this sensor to read the temperature of the return of the fan coil line? Will I have to ask my engineer to enable it or I can do it in the service menu on board the 150-A as I've been given the password?
When enabled, maybe as "hydraulic equilibrator" one, will influence the behaviour of the system?
Thank you for listening.
