You can connect your Nest thermostat on either OpenTherm or an on/off connection, but you will need to know whether your boiler has an OpenTherm option. You may also need a converter. We sell these through our partner Wifithermostaten.nl
The Nest can also be connected to an on/off connection on your boiler. Then your Nest thermostat communicates an on/off signal with your boiler. You do not need a converter for this.
There is a minimal saving difference between OpenTherm or on/off, which means that you often cannot compensate the costs of the converter. Therefore, if your boiler has both options and you need a converter for OpenTherm, you can choose to connect this on/off instead.
