Water Temperature Probe Installation; Ventilation Speeds; Electric Heating; Diffuser Irys - Airwell K OG LN Manual De Instalación Y De Mantenimiento

12.1.2. WATER TEMPERATURE PROBE INSTALLATION

The SW probe is already wired at the factory.
1. Cut the power supply to the unit.
2. Fit the probe onto the water inlet pipe.
3. Cover the connection with a protective sheath.

12.2. VENTILATION SPEEDS

The cassettes are supplied with 3 fan speeds, wired according to the model. Depending on the application, it is
possible to select from the 6 speeds, by connecting the motor wires on standby.
The disconnected, unused wire must be isolated in accordance with best electrical
wiring practices.

12.3. ELECTRIC HEATING

The electric heating system is equipped with 2 SAFETY DEVICES. One is reset automatically, the other is manually
reset. They cut off electrical supply to the heating resistances as soon as an operating anomaly is detected.
The electrical coil must never operate without the fan turning.

DIFFUSER IRYS

Manual reset

12.4. FAULT WARNING REPEATER

When the upper water level is reached (SB2 detector), the pump electronic logic control shuts down ventilation,
heating and the cooling valve with one of its wires connected to terminal 2.
A default relay (KD) or a warning light (I max 4A / 250 V) can be connected to terminal 6 (230 V NEUTRAL potential).
Provide electrical supply to the system on the same phase and coming from the same
circuit protection device as the cassette.
