The RF Digi 2 has been designed to offer you comfort and energy savings. It will be easily installed in your home and will control the ambient temperature according to the program. It will control through radio waves the RF receiver which may be fitted close to the boiler or the heating system.
The RF Digi 2 will control the ambient temperature according to 3 temperature levels.
- "comfort" temperature: this is the temperature for your hours of presence.
- "reduced" temperature : this is the temperature for your brief absences or during the night.
- "frost protection" temperature : this is the minimum temperature for long absences. It protects your dwelling from the risk of frost.

Where and how you should install the RF Digi 2
To control accurately the ambient temperature, the Digi 2 must be installed 1.5m above the floor, on an internal wall shaded from direct sunlight and from all thermal influences such as: television, lamps, heater,
The RF Digi 2 is delivered with a base. With this accessory, you can simply put it on a furniture (table, etc...). It is important to check that no external influence will perturb it (heater, window...).

You can also install it on an internal wall. Therefore, take out its wall mounting base.

Fix it to the wall.

Then replace the product on its base.

The IP43 wall mounting receiver
The IP43 wall mounting receiver can be easily installed close to the boiler.
The RF Digi 2 will control the ambient temperature in the dwelling and will transmit ON and OFF signals to the receiver. The output of the receiver will then switch ON and OFF the boiler.

Transmitter and receiver coding
Important: the transmitter and receiver assembly is factory coded and is therefore immediately operational. There is no need to recode.
