Deluxe roomthermostatdesign for control electric diffusers & floor heating systems. 2. Easy to use and provides you with a more comfortable living environment and saving energy. 3. Special design of double temperature modification avoids measurement influence from heating inside, provides you accurate temperature control. 4. Two parts design makes electric load separate from the thermostat. Individual output and input terminals with rated 20amp makes electric connecting more safe and reliably. 5. Pre-programmed for your convenience. Two programs selectable: Program a week 7 days up to four time periods and temperature set points each day or Program a week 7 days up to four time periods and turning-on/turning -off each day, it makes you to complement your lifestyle and to be applicable for many customers. 6. Programs are permanently held in non-volatile memory in the event of a power failure. 7. Attractive turn-cover design, most frequently used keys are located on the LCD for quick and easy access to information. Program keys are located on the interior to eliminate accidental setting changes. 8. Large LCD display with many messages for quick and easy readability and operation. Such as measurement and setting temperature, clock and program etc. 9. Temperature either F or C display for added model flexibility. 10. Constant hold feature allows continuous override 11. Temporary temperature override 12. Holiday status makes it keeping on a saving temperature during the presetting holidays 13. Unique lockable function makes all keys locked to eliminate accidental operation. 14. Low temperature protection 15. Internal or external sensor available 16. Infrared remote control optional 17. RS485 Communication interface optional
