To control heating applications in apartments, single-family homes, dormitories, and other residential as well as commercial spaces.
Automatically detect unnecessary energy consumption in the room and display it using Green Leaf on the thermostat. When the leaf is red, the thermostat setting has been changed. Touch the red leaf to return the setting to energy-optimized operation. See the User Guide (A6V11562455) for more information on this function.
The RDS110.R is designed to control heating applications in apartments, single family homes, dormitories, and other residential and commercial spaces.
The RDS110.R controls the following plant components with its peripherals:
RDS110.R with radiator valve actuator (SSA911.01TH):
RDS110.R with the wireless receiver (RCR114.1):
NOTICE
When selecting the gas boiler application, ensure hydronic heating is used. The RDS110.R is not calibrated for use in combination with a gas-fired ducted heating system.
The RDS110.R can control a maximum of 6 receivers in parallel, with the same control settings.
The RCR114.1 has two relay outputs, one of which is for heating equipment (listed above).
The other relay is available to optionally control a domestic hot water (DHW) boiler, humidifier, or dehumidifier.
The RDS110.R has two multifunctional inputs, optional and configurable for:
NOTICE
See the User guide (doc ID: A6V11562455) for more information about input configurations.
NOTES:
The room thermostat consists of the following parts:
1 | Tap to display detailed information and additional settings. |
2 | Tap to display additional measurements, for example, outside air temperature. (Only if external sensor is connected) |
3 | Tap to display notifications (only visible if applicable) |
4 | Room temperature |
5 | Tap to toggle between “At home” and “AWAY”. |
6 | Displays whether the thermostat is following a schedule ( ● If you are connected to a network and you have set your schedule, the thermostat follows your schedule. Your temporary change of the temperature setpoint only takes effect during the currently scheduled mode. ● If you are connected to a network but no schedule is set, the thermostat applies the system’s default schedule. For more information about default schedules, see Time-based schedules. ● Without a network connection or valid time, the thermostat cannot retrieve schedule information from the Cloud. It only works under the “Comfort” mode. |
7 | Tap or slide to change the room temperature setpoint. * |
NOTICE!
The RDS110.R screen switches to idle mode after 2 minutes of inactivity. The idle screen of the RDS110.R can be displayed as a simple screen with basic room values, or as a blank, black screen. The simple screen is the default setting.
1 | Relative room humidity |
2 | Room air quality status:“Good” . (Displayed only if an external air quality sensor is connected to the thermostat) |
3 | Outside air temperature (displayed only if an external temperature sensor is connected to the thermostat) |
4 | Green leaf: Energy-optimized mode. Red leaf: Tap to restore the energy-optimized mode. |
5 | Room temperature |
NOTE: The icons displayed in idle mode may differ if you’ve connected external sensors to your thermostat. For example, the idle screen may display room air quality status or outside air temperature if a related external sensor is connected to the thermostat. However, the relative room humidity value and green leaf indication are always displayed on the idle screen.
