OpenTherm with Y plan setup
We have an Ideal Logic Max Heat 24 boiler which has OpenTherm compatibility that I'm looking to take advantage of. We have a Tado wired thermostat working in wireless mode after we invested in the wireless add-on receiver a number of years ago. Both the thermostat and receiver appear to have low-voltage terminal connections that suggest these pre-date the removal of OpenTherm from UK devices.
We have a system boiler (gravity-fed, Y plan setup with hot water tank, pump and 3-way valve) so we're currently using the switched live wiring configuration in the receiver. We're able to control heating and hot water using Tado.
Is there a way to get Tado to speak to the boiler using OpenTherm and maintain existing functionality, either by connecting the OpenTherm connections between either the thermostat or receiver to the respective connection on the boiler and removing the switched live between the receiver and the boiler?
After reviewing the install guides, they show either OpenTherm or switched live to support the tank stat, pump etc.
Any advice would be greatly appreciated!
Thanks in advance,
