**niko 221-52204 Fourfold Push Button With LEDs And Comfort Sensors Instructions

**

This fourfold push button can be configured to control a variety of actions and routines in a Niko Home Control II installation on bus wiring. It is fitted with programmable LEDs that provide (inverted) feedback on the action that is being performed. In addition, the push button can serve as an orientation light when the LEDs are ON.
Thanks to its integrated temperature and humidity sensor, the push button also supports multi-zone climate and ventilation control, allowing you to increase your energy efficiency and overall comfort.

Its multi-purpose temperature sensor can be set to control a heating/cooling zone within a Niko Home Control II installation, as a basic thermometer or to create certain conditions (e.g. control sunscreens).
The humidity sensor can also be used within routines. For example, to perform automatic ventilation control in a bathroom or toilet.

The fourfold push button features an easy click-on mechanism for wall-mounted bus wiring controls and is available in all Niko finishing.

Technical data

Fourfold push button with LEDs and comfort sensors for Niko Home Control, gold coated.

Function:
When using the push button’s temperature sensor for heating/cooling zone control, make sure the room temperature can be measured accurately by eliminating as many factors as possible that may inhibit the thermostat’s ability to accurately control the room temperature.
When used as thermostat, DO NOT mount the push button:
- in direct sunlight
- on an exterior wall
- within the immediate vicinity of a heat generating source (heater, radiator, etc.) or electrical equipment that may radiate heat (TV, computer, etc.).
- behind a curtain
Select the push button that best suits the above conditions to control your heating/cooling zone
Do not allow air to circulate behind the push button. If needed, use an airtight wall-mounting box or fill in any gaps in the flush-mounting box or bus cable duct using PU foam
Combine the push button’s temperature sensor with a heating or cooling module for multi zone control or a switching module for electrical heating
Combine its integrated humidity sensor with a ventilation module to perform automatic ventilation control
Set points and week programmed are managed via the app
Calibration is managed via the programming software
Maximum number of push buttons set as a temperature sensor per installation: 20
Temperature sensor range: 0 – 40°C
Temperature sensor accuracy: ± 0.5°C
Humidity sensor range: 0 – 100 % RH (non-condensing, nor icing)
Humidity sensor accuracy: ±5 %, between 20 – 80 % RH at 25 °C
Complies with the European standards EN 60669-2-1, EN 63044-3, EN 63044-5-2
Material central plate: The central plate is enamelled and made of rigid PC and ASA.
Lens: On the external corner of the four keys on the push button there is a small amber-coloured LED (1.5 x 1.5 mm) to indicate the status of the action.
Colour: enamelled gold (approximately NCS S 3020 – Y, RAL 1000)
Fire safety
- The plastic parts of the central plate are self-extinguishing (comply with a filament test of 650°C)
- The plastic parts of the central plate are halogen-free.
Input voltage: 26 Vdc (SELV, safety extra-low voltage)
Dismantling: To dismount simply pull the push button off the wall-mounted printed circuit board.
Impact resistance: After mounting, an impact-resistance of IK06 is guaranteed.
