16A 3A programmable thermostat Digital Temperature warm Controller for underfloor heating boiler heater room radiant manifoldstart

Technical Parameters Temperature setting range: 5-35 temperature

Temperature accuracy: +/- 1 temperature

Antifreeze temperature: 5temperature

Temperature control tolerance: +/1-

Temperature sensor: NTC Output mode: relay output Native power

consumption: <1 W Power supply

voltage: 220V +/- 10% 50 / 60HZ

NOTE: 

    1, For the 3A thermostat, there is only built-in sensor, there is no external heating sensor probe, and it can only worked for water underfloor heating system.

    2, For the 16A thermostat, it contain built-in and external sensor probe, and it can worked for both water/electric underfloor heating system, boiler and heater, etc.
