Thermostat stuck open.

[Fizz5]

Hi, I’ve been trying to fit some new smart Tado thermostats when doing so I’ve discovered my thermostat pins are seized fully open.

Any suggestions on how to fix? Or do I just need to buy new valves?

I’ve attached a photo of the valve for ref there’s 3 radiators I’ve tried and all the same.

Thanks

Those valves look ancient. Always best to get new ones when fitting a smart home system - old ones can be stiff as you've discovered, and this will reduce battery life and increase wear & tear on your expensive new valve heads
