Will changing to modulating control make old controller redundant?

Hi, long term Tado user here and now looking to change to modulating control.

My current set-up sees a combi boiler connected to the original boiler control which in turn connects to the wired thermostat.

Question is will the original boiler controls need to be removed if I want to get the full benefits of modulating control.

In some ways I'm thinking that might actually be better as it removes wall clutter and a point of failure.

Any thoughts?

    Actually, thinking about it. As soon as I move from high voltage to the low voltage connection I'm assuming the old controller might stop working?

    Digital modulating thermostats often require a direct connection to the boiler, but to get a definitive answer you'll need to provide brand and model number for the old device.

    Almost certain that you’ll need to wire the Tado thermostat in directly, but like grilled cheese says, really depends on your device.

    If you switch to a digital connection, make sure to tell Tado support to set your boiler’s max flow heating temperature to 55c, as otherwise it defaults to a much higher temp and overrides the boiler settings.
