EN DIGITAL THERMOSTAT IT 201
The IT 201 thermostat is designed to control heating
systems. Unlike standard home thermostats, IT 201 has
two separate and wirelessly connected units (thermostat +
receiver).
The receiver is a switching device used to connect
heating systems, and a thermostat is a portable control
unit for handling and setting the temperature. The units
communicate with each other using a radio signal.
The advantage of the system is the variability and easier
availability of temperature control.
Important notes
• Read the user manual not only for the thermostat, but also
the the boiler.
• Turn off the power supply before installing the thermostat.
• We recommend installation by a qualified technician.
• Be aware of the required standards for installation.
• The electrical circuit should be secured with a fuse that
does not exceed 20 A.

Safety
Risks due to poor handling
Due to poor handling of the product you can harm yourself
and cause material damage.
• Read the accompanying instructions carefully, especially
the chapter on safety and important notes.
Danger of malfunctioning
• Ensure that the air in the room can circulate freely around
the thermostat and that the thermostat is not covered by
furniture, curtains and other objects.
• Only operate the heating system if it is in technically
perfect condition.
Freezing damage due to too low room
temperature
If the room temperature is set too low in some rooms, the
heating system can be damaged due to freezing:
• Ensure that during the frost period the heating
system remains in operation and that all rooms during
your absence are sufficiently heated.
• Default frost protection temperature is 5 °C and can be
changed in the range from 0 to 17 °C.

Operating via receiver
• When the receiver is in normal operation mode (AUTO
MODE), by clicking on the ON/OFF button, the receiver
turns off and goes to OFF MODE.
• If we want to turn AUTO MODE on the receiver, to
change the state from OFF MODE, it is necessary to click
twice on the ON/OFF button.
• If the receiver is in ON MODE, it is necessary to press the
ON/OFF button once to change the state to OFF MODE,
and then press the ON/OFF button again to change the
state to AUTO MODE.
• When the thermostat is in SYSTEM OFF mode, by
pressing the ON/OFF button on the receiver, we exit from
OFF MODE to enter MANUAL MODE. (SYSTEM OFF mode is a
mode whose state changes apply to all receivers that are connected to that thermostat)
• If we want to start SmartPairing mode via the receiver,
we need to hold the ON/OFF button until the green color
appears on the receiver and then release the button.
• If we want to start a FACTORY RESET via the receiver,
it is necessary to hold the ON/OFF button until the red
color appears on the receiver, and after that the receiver
returns to the factory settings. After that, receiver enters
SmartPairing mode to reconnect with thermostat.

appropriate handling. Here are some tips to handle it properly:
1. Before using the product, read the manual carefully.
2. Do not expose the product to direct sunlight, extreme
cold and humidity, and sudden changes in temperature.
This lowers the measurement accuracy.
3. Do not place the product in a place subject to vibration
or shocks - it may cause damage.
4. Do not expose the product to excessive pressure,
shocks, dust, high temperature or humidity - this can
cause degradation of product functionality, reduced

plastic parts.
5. Do not expose the product to rain or moisture, dripping
or splashing water.
6. Do not place any open flames on the device, such as a
lit candle, etc.
7. Do not place the device in places where there is
insufficient air-flow.
8. Do not place any objects in the vents of the unit.
9. Do not touch the internal power openings of the device
- they may be damaged and thus automatically void the
