However because the TADO Smart Radiator Thermostat are not able to measure the temperature in the water, this adaptor instead makes it possible to work as a Telestat just like the more expensive underfloor heating system controls.
Maximum Recommended Water Temp. System: 100°C
This Adapter is recommended for use with Underfloor Heating and Radiator Systems where the system water Temperature is higher than 45°C, We also recommend this Adapter if the Temperature is not known.
For Lower Water Temp. Systems, See This Adapter.
