24V White Universal Touch LCD Screen Heat Pump Programmable Smart Air Conditioner Thermostat for AC (STN855) For Hotel
This is the STN855 supplied for hotel projects, where one control has to cover fan coil units, boilers, radiators, floor heating and ventilation in the same building. The touch LCD replaces a button keypad on the guest-facing surface, the schedule runs 5/1/1, and the Omron relay switches 6 A with 2 A inductive load. Housing colour can be customised alongside the white, blue and green backlight options.
