TX-937-H-W is avalaible for underfloor heating system. It had built in WIFI module which is availble for remote control by cell phone, pad and laptop. Models are with NTC sensor to detect ambiet temperature and do the control by comparison with the setting temperature.
TX-937-H series are available for boiler, manifold and underfloor heating system with 7-day, 6-period time program control.Models are with NTC sensor to detect ambient and floor temperature and do the control by compared with the setting one. Manual,time program and temporary mode can be switched any time by pressing the relevant keys. De-frost protection function will be active when ambient temperature below 5 °C , prevent water pipe from freeing and burning.
