Use

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):

• Radiator with valve (SSA911.01TH)
  NOTE: The RDS110.R can control a maximum of 6 valve actuators in parallel, with the same control settings.

RDS110.R with the wireless receiver (RCR114.1):

• Gas boiler
• Radiator with pump
• Electric floor heating
• Fan with electric heating
• Floor heating with valve
• Floor heating with pump
• Electric radiator
• Electric boiler
• Generic heating device

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:

• Operating mode switchover contact
  • The thermostat switches to the “OFF” mode if the input has been configured as Normally Open. Useful for a room or key card.
• Remote room temperature sensor
  • The remote temperature sensor can acquire the current room temperature. If the sensor input signal is lost, the thermostat controls the room according to the internal sensor.
• Floor temperature sensor
  • The floor heating limitation function prevents the floor temperature from exceeding a preset value.
• Outside air temperature sensor
  • The outside air temperature sensor can acquire outside air temperature information for display on the touch screen.
• Remote humidity sensor
  • The thermostat can control a standalone humidifier or dehumidifier. The relative humidity is measured by the remote humidity sensor or internal humidity sensor.
• VOC and CO2 sensors
• Condensation monitor
• Universal contact. A notification shows up in the mobile application when the input status switches to “Normally closed” (the circuit is closed).
• Presence detector. The thermostat switches from “Unoccupied” to “Comfort” if the detector detects someone in the room. It remains in “Unoccupied” for a maximum of one hour after the last presence detection.

NOTICE
See the User guide (doc ID: A6V11562455) for more information about input configurations.

Topology

NOTES:

1. Install the receiver close to the RDS110.R if possible. The communication range in a building is typically 60 m, without any blockages. Note that range can vary, because walls, floors, wireless interference and other factors may reduce the signal strength.
2. Add a repeater (RCR114.1) if the connection fails due to low signal strength (distance or blockagers [walls, and so on]).
3. The thermostat can only connect to one heating system. It cannot simultaneously control the wireless relay and the valve actuator.
4. The thermostat can control up to six wireless relays or valve actuators.

Mechanical design

The room thermostat consists of the following parts:

• Housing front with touchscreen
• Housing rear with terminals and temperature sensor
• Metallic mounting plate for wall mounting
• Accessories

Operation and settings

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 () or your setpoint changes permanently (). Following a schedule can mean the following: ●        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. * The thermostat is in heating mode – at some point, the relay will be energized, depending on the heating demand and application type.  The thermostat is not in heating mode.

NOTICE!

•  There is a few seconds delay between the color change in the temperature bar and the reaction of the relays.
• After initial setup of the thermostat, the displayed room temperature may not be correct because the temperature sensors need time for calibration. Wait for at least one hour for the thermostat to calibrate.

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”   , “Okay”, “Poor” . (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.
To set idle display

• On the Home screen, tap , then tap until the “Settings” page displays.
• Tap and then tap to set the idle screen as pure blank or with values.

Notes

Security

CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property damage
● Observe any national provisions and comply with appropriate safety regulations.

Engineering

See the product documentation for information on engineering, selection and sizing connecting cables for supply voltage and field devices.

Installation

The mounting plate of the thermostat can be installed on CEE/VDE conduit boxes and on square boxes 75 x 75 mm. For installation on a rectangular conduit box (for example 105 x 72 mm), accessory ARG100.01 must be ordered, which includes a white decorative frame and a bigger mounting plate.
WARNING
No internal line protection for supply lines to external consumers Risk of fire and injury due to short-circuits

• Adapt the line diameters as per local regulations to the rated value of the installed overcurrent protection device.
• The AC 230 V mains supply line must have an external circuit breaker with a rated current of no more than 10 A.
• Use only AC 230 V isolated wired cables, as the conduit box carries AC 230 V mains voltage.
• Inputs X1-M-X2: Several switches may be connected in parallel. Consider the overall maximum contact sensing current of the switch rating.
• Disconnect from power supply before removing the thermostat cover.

Commissioning

See the Quick guide and User guide (see Product Documentation) to configure your device.
Commissioning includes the following:
