Smart Thermostat RDS110 To control heating applications in apartments, single family homes, dormitories, and other residential as well as commercial spaces.
Room thermostat features ● Direct temperature and operating mode selection ● RoomOptiControl function with Green leaf *) button for energy-optimized operation ● Air quality indication: “Good”, “Okay”, “Poor” ● Temperature setting limitation for use in public spaces ● Screen lock protection against unauthorized access ● Manual switchover between “At home”, “Away” and “OFF” on touch screen ● Room temperature control using the built-in temperature sensor or an optional remote sensor ● Optional temperature aver
● ● ● Monitoring of temperature and humidity Monitoring of indoor air quality: “Good”, “Okay”, “Poor” Secure access and data transmission with the Siemens Cloud Computing Platform Use The RDS110 is designed to control heating applications in apartments, single family homes, dormitories, and other residential as well as commercial spaces.
Operation and settings Normal display 1 Tap to display detailed information and additional setting possibilities. 2 Shows if the system is in an energy-optimized mode. If the leaf is red, predefined settings were changed. Tap the red leaf to restore energy-saving mode. The leaf again turns green. 3 Room temperature*) 4 Tap to toggle between “At home” and “Away”. 5 Shows if the thermostat works automatically ( ) or manually ( ).
Idle display 1 Room relative humidity 2 Shows room air quality: ● If the icon is green, air quality is good. ● If the icon is orange, air quality is okay. ● If the icon is red, air quality is poor. 3 Shows if the system is in an energy-optimized mode. If the leaf is red, predefined settings were changed. Tap the red leaf to restore energy-saving mode. The leaf again turns green. 4 Room temperature Note: Depending on how the thermostat is set up, the displayed options in idle mode may differ.
