How to connect OTGW between Remeha Tzerra and eTwist thermostat

Post by Ritmeester » Thursday 01 February 2018 17:53

I have a question on how to connect the OTGW between the Remeha Tzerra and eTwist thermostat.

I have this equipment:
Remeha Tzerra Plus

and some box on the wall between the eTwist and the Tzerra

So, how to connect this OTGW PCB?

Hi,

I have the same setup here ( only waiting for the optocouplers).

As far as I read here viewtopic.php?f=38&t=15099 It should be inbetween the gateway and the boiler, as this is OT protocol.

I am wondering if you can override the room setpoint ( sow I finally can get geofencing working on the etwist)

Thanks for your reply. But must I connect the OTGW PCB in “series” or in “parallel” ?
