ELECTRONIC FLUSH-MOUNTING HUMIDISTAT
 Read all instructions carefully

• Install the humidistat in a 3-module flush-mounting box (type 503) at a height
of about 1.5 m above the floor in an area which respects as much as possible
the average humidity conditions of the whole room. Avoid installation near doors
or windows, in niches, behind doors and curtains or in positions with excess or
total lack of ventilation, in order to prevent the humidity reading measured by the
probe from being somewhat offset.
• The device is sold already mounted with anthracite colour. To transform it in the
white version, remove the knob and the cover, acting on the hooks placed on
the upper and lower side of the device and mount the cover and the white knob
included in the package.
• Make the connections by respecting the diagrams described in this manual.
• Fix the device inside the 3 modules box in compliance with the assembly
diagrams described on the back of this instruction sheet. The installation
accessories included in the package or can be purchased separately
(see BOX 7) allow for adaptability with the main domestic range.

information to users pursuant to art. 14 of the directive
2012/19 / EU of the european parliament and of the council
of 4 july 2012 on waste electrical and electronic equipment (WEEE)
If the crossed-out bin symbol appears on the equipment or packaging,
this means the product must not be included with other general waste
at the end of its working life.
The user must take the worn product to a sorted waste center,
or return it to the retailer when purchasing a new one.
Products for disposal can be consigned free of charge (without any new purchase obligation)
to retailers with a sales area of at least 400 m2, if they measure less than 25 cm.
An efficient sorted waste collection for the environmentally friendly disposal of the used device, or its
subsequent recycling, helps avoid the potential negative effects on the environment and people’s health,
and encourages the re-use and/or recycling of the construction materials.

6MOUNTING
Note:
1. For installation with the BTicino Livinglight AIR series if the box extension is not present (adapter which increases the depth of the recessed box)
we recommend using the Livinglight AIR installation frame.
2. Choose the adaptability frame based on the compatibility table (see BOX 7) for the domestic range.
3. Insert, if necessary, plastic elements (see BOX 7).

• Use the selector switch to turn on or off the humidistat:
- position 0: humidistat off, no regulation
- position |: humidistat switched on, active regulation for detected humidity values exceeding the set value.
• Use the knob to set the desired humidity level. It’s possible to set values between 30% RH and 90% RH.
When the humidity value present in the room exceeds the set value, the red LED switches on and the relay closes the contact between terminals 1-2.
Note: In order to preserve the life of the system, the minimum time between a relay switching and the next one is 1 minute. However, the led status updating is
immediate. Therefore, after using the regulation knob, it is possible to find a discrepancy between what is indicated by the led and the actual status of the relay. This
condition lasts for up to 1 minute.
The device has two ring nuts to limit mechanically the range of settable values if the humidistat is installed in public places or in hotel rooms.
To limit the range, proceed as follows:
- Set the knob in an intermediate value of the desired range
- Remove the knob.
- Under the knob there are two ring nuts marked by the word “min” and “MAX”, respectively for the lower and upper
limit.
- Turn the “min” ring nut clockwise and “MAX” anticlockwise until the minimum value range (see the humidity values
reported on the cover).
- Turn the “MAX” ring nut anticlockwise and until the maximum value range (see the humidity values reported
on the cover).
- Replace the knob, making sure that the indicator of the setpoint on the knob is in the same position when the knob has
been removed.
To remove the limitation to the setpoint and reset the range 30% ÷ 90% RH turn the two ring nuts up to bring the locks of limitation in a position outside the range
30% ÷ 90% RH.
OPERATION
Error probe signal
The humidistat signals the error probe condition by blinking the led 2 times per second.
In this case the regulation is inhibited and the relay contact remains between terminals 2 and 3.
