I’m a new user, recently took delivery of a built Touch v6.0 (I meant to get a kit, but I must’ve mis-clicked ).
The device booted up brilliantly, I had no trouble connecting it to WiFi & openHAB on my phone, but I’m yet to connect it to my boiler.
I’ve spent an hour or so searching the hestiapi.com and this forum for a wiring schematic, but the only documentation I can find for installation is for installing software, or installing the pcb/screen into a case. I want to wire it to my boiler. Others have asked for help replacing existing thermostats, so I can try to reverse engineer instructions in other threads to see if they apply to my boiler too, but I’m wondering if I’m missing something obvious.
Is there any documentation that describes a standard physical wiring case, a schematic of the Touch v6.0’s output, or a specification detailing the behaviour of the device, to assist anyone completing wiring/installation to a boiler?
I’m assuming that when the HestiaPi Touch v6.0 calls for heat or hot water, 220v (or whatever supply voltage is applied to the AC-L terminal) is connected by the relay to the Heat or Water output. Is that right?
I’m guessing I’ve missed something obvious (apologies if I have). Does such documentation exist?
Thanks for your help, and the hard work of everyone who’s made this fab little thing a reality!
p.s. My boiler never had a thermostat installed (Vaillant Turbomax 824E, if you’re interested), so rather than install new wires, I’m considering adding an ESP8266 controlled 240v relay in the boiler cabinet (in my kitchen, not a great place for the central heating thermostat), which HestiaPi triggers remotely from a living area. One step at a time though!
