SyxthSense SST-x-P304 are elegant programmable room thermostats with a large backlit LCD display. The thermostats have 5+2 (weekday / weekend) programmable time clock for quick setup but can also be configured individually for each weekday. Each day has 4 programmable setpoints to provide maximum energy efficiency and comfort.

SST Intelligent Programmable Room Thermostat Operation  
The SST-x-P304 range has internal accurate temperature sensor with option to enable external temperature sensor. If the external sensor has been enabled then the control will be carried out using the external temperature sensor.  
SST-x-P304 thermostats have lockable keypad to prevent unauthorised change in the settings. Intelligent sleep mode allows gradual reduction of temperature at night time providing further comfort and energy savigs as the night setpoint can be set lower as usually in similar installations.  
SST Intelligent Programmable Room Thermostat Sleep Mode  
Other advanced features include external override facility to switch the heating system to day mode from a telephone or a mobile phone interface. Thermostats can also be networked to a central system master via Modbus RTU RS-485 communication network.  
SyxthSense SST thermostats have 16A rated output relay allowing them to be used both water based heating systems as well as with electric heating.
