Hi Guys, Currently I have a Greenstar 30si boiler which runs our 3 zones of Underfloor heating (Believed to be a water system as it only heats when the boiler is on). The three thermostat are John Guest/Watts Industries Milux units. I am looking into getting a smart system Hive/Nest/Tado. when I contacted Tado regarding compatibility they asked me to find out " if this current thermostat switches less than 6 Amps.". As apparently if the Amps is higher than 6 amps it will damage their units. How can I find out this information. Any help is greatly appreciated TIA
