2 Summary
2.1 Brief description
Smart Thermostat RDS110.R is designed to control your heating system in
apartments, single family homes, dormitories and other types of residences as well
as light commercial spaces. It controls your heating system wirelessly by
connecting to the smart receiver (RCR114.1) or smart valve actuator
(SSA911.01TH).
As a smart thermostat, the RDS110.R can be controlled locally and remotely, via a
mobile application on your smartphone. The mobile application offers additional
features such as intuitive schedules and temperature trends to ensure that your
home is comfortable and saving energy at the right times.
2.1.1 Operation overview
You can control the heating system using the thermostat or mobile application.
Some control operations can be performed from both ends, whereas others are
limited to either the thermostat or the mobile application:
●Configuration of the thermostat is possible only on the thermostat itself, such
as selecting the settings of the heating applications and connecting the
thermostat to the wireless accessories (smart receiver or valve actuator)
●Daily operation is possible both on the thermostat and with the mobile
application, for example, changing the temperature setpoint, switching the
thermostat on or off
●Advanced operation is possible with the mobile application, for example,
creating the time schedule and viewing energy trends

3 Mounting and installation
NOTICE
We recommend hiring licensed installers to mount and install the thermostat.
●The thermostat is suitable for wall mounting.
●The recommended height is 1.50 m above the floor.
●Do not mount the thermostat in recesses, shelves, behind curtains or doors, or
above or near heat sources.
●Avoid direct solar radiation and drafts.
●Seal the conduit box or the installation tube if any, as air currents can affect
sensor readings.
●Adhere to allowed ambient conditions.
In addition to the following instructions, a step-by-step graphical instruction
showing how to assemble different components and mount the thermostat can be
found in the Mounting instructions. The following part only gives textual instructions
so as to assist you with safe and successful mounting.
1. Switch off power to your heating system and old thermostat by using your
home’s breaker box.
2. Remove the cover of your old thermostat.
3. Label the wires according to your old thermostat terminal designations, using
the stickers provided together with the thermostat. It is also helpful if you take a
picture of the current wire connections for reference later on.
4. Disconnect all the labeled wires and then remove your old thermostat.
NOTICE! Do not dispose of your old thermostat as part of household
waste if it contains mercury in a sealed tube. Contact a thermostat
recycling organization, for example, www.thermostat-recycle.org, for safe
disposal of your old thermostat.
5. Determine if you need to have more wires connected to the power unit to be
installed. If so, prepare the wires and label them accordingly. We strongly
recommend hiring installers to connect the wires.
6. Seal the conduit box or the installation tube to prevent entry of cold or hot air
and make sure the temperature readings of the internal sensor are correct.

7. Screw the mounting plate tightly on the conduit box using a screwdriver,
making sure the mounting plate is placed correctly (the part with the upward
arrow placed on the top).
8. Connect the labeled wires to the terminals following the thermostat terminal
designations. Use a screwdriver to tighten down the screws to secure the
inserted wires.
NOTICE! There are four pairs of L and N terminals on the power unit.
However, you can combine any L with any N terminal.
9. Screw the power unit on the mounting plate tightly.
10. Attach the front module horizontally. Ensure that each side of the front module
aligns with the power unit and press the corners in the order illustrated below:
Top (1); bottom (2) until each corner clicks in place. Note: You must discharge
static electricity from your body before mounting the front module. For example,
touching the wall can help discharge static electricity.
11. Switch the power back on to your heating system and thermostat by using your
home’s breaker box.
See the Mounting instructions for more information.
●Comply with local regulations to wire, fuse and earth the thermostat. Connect
the conduit box to earth (safety ground).
●Adapt the line diameters as per local regulations to the rated value of the
installed overcurrent protection device.
●The line voltage cables and signal cables must be arranged separately.
●X1, M and X2 wires operate at SELV (Safety Extra Low Voltage) level. Do not
insert cables with AC 230 V mains voltage into terminals X1, M and X2 and
vice versa.
●Isolate the cables of inputs X1, M and X2 from AC 230 V mains voltage.
●The AC 230 V mains supply line must have an external circuit breaker with a
rated current of no more than 10 A.
●Screw down all terminals regardless of whether cables are connected or not.
●Properly size the cables to the thermostat.
●Screw down the cables tightly and make sure no bare copper is exposed.
●Disconnect from power supply before removing the front module and the
mounting plate.
●Use a cable lug to avoid touching of mains and neutral wires, if the power cable
is made of RVS wires.

4.1 Setup wizard
When your thermostat is powered up for the first time, a setup wizard displays to
guide you through the following procedures:
●Setting a display language
●Setting an administrator password
●Setting up a network connection and choosing the network connection type
●Selecting an equipment type and setting up the details
●Configuring time and date
●Specifying a name to the location where the thermostat is installed
For more details, see the Quick guide.

the following:
●If there is a network connection and you’ve also set your schedule, the
thermostat follows your schedule. Your temporary change of the
temperature setpoint only takes effect during the currently scheduled
mode.
●If the network is connected but no schedule set, the thermostat applies
the system’s default schedule. For more information on the default
schedule, see Time-based schedules.
●Without network connection or valid time, the thermostat cannot retrieve
schedule information from the Cloud. It always works in the “Comfort”
mode.

Relative room humidity
The thermostat works following a schedule. If you haven’t set one, the
thermostat works following a default schedule. This default schedule
could be set by the system, or specified by yourself if you have changed
the default setpoints of some operating modes under “Advanced
Settings” > “Optimization”.
When this icon is toggled on, temperature setpoint changes can only be
maintained within the current scheduled mode and will be overridden to
the scheduled setpoint when the next scheduled mode starts.
NOTE: If the thermostat has never been connected to a WLAN network,
it cannot read the real time from the network and thus cannot follow a
schedule. In this case, it always works under the “Comfort” mode.
The thermostat doesn’t work following a schedule. All of your temporary
setpoint changes work continuously if this icon is toggled on.
