Notes
Safety
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
●Observe national provisions and comply with the appropriate safety regulations.
WARNING
Explosion due to fire or short-circuit, even with discharged batteries
Risk of injury due to flying parts
●Prevent the batteries from coming in contact with water.
●Do not recharge batteries.
●Do not damage or disassemble batteries.
●Do not heat batteries over 60 °C.
WARNING
Electrolyte leakage
Chemical burns
●Only grasp damaged batteries using suitable protective gloves.
●If electrolyte comes into contact with eyes, immediately rinse eyes with plenty of water.
Consult a doctor.

Mounting
●RDZ100ZB is suitable for wall mounting.
●RDZ101ZB is suitable for wall mounting and table standing.
●Recommended height for wall mounting: 1.50 m above the floor.
●Mount the thermostat close to Connected Home Hub if possible. Note that the
communication range can vary because walls, floors, wireless interference and other
factors may reduce the signal strength.
●Do not mount or place the thermostat in recesses, behind curtains or doors, or above or
near heat sources.
●Do not mount or place the thermostat near large metal structures or other construction
elements with fine metal meshes like special glass or special concrete.
●Do not mount or place the thermostat in a location where it is exposed to dripping water,
moisture or excessive heat.
●Do not mount or place the thermostat on metal surfaces.
●Avoid placing RDZ101ZB inside or near metal or sources of radio or electromagnetic
energy or interference, for example, do not place under or on top of a WLAN router.
●Avoid direct sunlight.
●Seal the conduit box or the installation tube if any, as air currents can affect sensor
readings.
●Observe allowed ambient conditions.
●Keep the thermostat out of the reach of people (including children) whose physical,
sensory or mental capabilities, knowledge, or experience prevents them from using the
thermostat safely without supervision or instructions.
●If the adapter plate ARG101 is used, assemble its mounting frame and mounting plate in
such a way that the bigger round spot embossed on the mounting frame is atop.
●Make sure wiring, protection, and earthing comply with local regulations.
●Switch off power to the heating system before mounting/dismantling and wiring.
●Correctly size the cables to the thermostat and the valve actuators.
●Use only valve actuators rated for AC 24…230 V.
●External preliminary protection with maximum C 10 A circuit breaker in the supply lines is
required under all circumstances.

Installation
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 fuse.
CAUTION
Risk of explosion
Personal injury and property damage
●Insert the battery at the correct polarity (+/-) using the illustration in the battery
compartment.
●Insert only the correct battery types according to the indication in the battery
compartment.
●Store, transport and dispose of the batteries in compliance with local requirements,
regulations and laws, and observe the instructions of the battery manufacturer.
Observe the following:
●The batteries must be undamaged.
●Do not mix new and used batteries.
Commissioning
●The thermostat is ready for commissioning after batteries are inserted.
●After joining is initiated from the mobile application, tap and hold for more than five
seconds on the thermostat to join the Zigbee network.
●After joining the network, set schedules and change parameters in the mobile application
to ensure optimum performance of the entire system. See the operation manual
(http://www.siemens.com/download?A6V13360586) for more information about
parameters.
The wireless room thermostat RDZ101ZB requires a wireless output module, e.g.
RCR110.2ZB, to control HVAC equipment. Binding the thermostat to the output module is
automatic, if located in the same room. Max. 5 wireless output modules can be bound to one
wireless room thermostat RDZ101ZB.
Operation See the operation manual (http://www.siemens.com/download?A6V13360586) for detailed
information.
Maintenance Apart from replacing batteries upon low battery notification on the local screen or in the
mobile application, the thermostat is maintenance-free. See the operation manual
(http://www.siemens.com/download?A6V13360586) for information about battery
replacement.
