Thermostat
Manual

The IT 101 thermostat is designed to control heating
systems. Unlike standard home thermostats, the IT
101 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 heating system.
• Turn off the power supply before installing the
thermostat.
• We recommend installation by a qualified installer.
• The electrical circuit should be secured with a fuse
that does not exceed 20 A.
• Be aware of the required standards for installation.

Safety
Risks due to poor handling
Due to poor handling, 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.
• Make sure that all heater valves in the room where the
thermostat is installed are fully open.
• Only operate the heating system if it is in technically
perfect condition.
Damage due to loss of wireless communication
Low voltage in the batteries that power the thermostat
may result in interruption of wireless communication. In
the event of a loss of wireless communication between the
receiver (heating system switching unit) and the thermostat
(room control unit):
• If the receiver is on and the thermostat is off, after 10
minutes orange light signal on the receiver starts to blink.
• If the thermostat is on and the receiver is off, after one
minute the symbol on thermostat’s display starts to blink.

In both cases the heating turns off. The communication
might be lost due to old batteries in the thermostat or
because the thermostat is too far away from the receiver.
Keep in mind the connection status (light signal) of the
receiver and the thermostat.
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.
• The thermostat has an integrated frost protection,
which is activated at 7 °C. Frost protection activates the
heating and protects the system from freezing.
Proper use of the device
Improper use can result in health and life hazards to the
plant operator or third parties.
This product is not intended for use by persons (including
children) with limited physical, sensory or intellectual
