Smart Room Thermostat
Room thermostat for the control of heating applications in apartments, single family homes, dormitories
and other residential-type as well as light commercial spaces. With remote access via computer, tablet,
or smartphone using the Siemens Comfort Cloud service.
Room thermostat features
 Backlit, auto-dimming 90 mm color LCD touch screen for intuitive local operation
 Mobile app for smartphones
 Air quality indication via built-in sensor
 Operate automatically following a scheduler
 Direct temperature and operating mode selection
 RoomOptiControl function with Green leaf button for energy-optimized operation
 Temperature setting limitation for use in public spaces
 Screen lock protection against unauthorized access
 Manual switchover between "Home", "Away" and "OFF" on touch screen
 Room temperature control using the built-in temperature sensor or an optional remote sensor
 Optional temperature averaging using an additional remote temperature sensor
 Patented self-learning algorithm with PID response (patent pending) guaranteeing optimum
temperature control performance in all room types
 Optimum start control function that advances the switch-on time to ensure the selected setpoint is
reached as required
 Floor temperature limitation using a remote sensor in electric floor-heating applications
 Humidity control using the built-in humidity sensor or an optional remote sensor
 Presence detection using a built-in PIR sensor or approach sensor
 Two multifunctional inputs, optional and configurable for operating mode switchover contact (e.g.
window contact), remote room temperature sensor, floor temperature sensor, outside air temperature
sensor, remote humidity sensor
 Two relay outputs for heating equipment, extra output for domestic hot water (DHW) boiler,
humidifier or dehumidifier
 Periodic pump/valve operation to protect against seizing
 Navigation wizard for guided, fast commissioning
