MAIN FEATURES
APPLICATION: module for installation inside wall mounting housings, cabinet humidity housings, or mounting board of controls, to control fans, humidifier or dehumidifier. The incorporation and ingress protection must be made by the integrator
MEASURING ELEMENT: hygroscopic polymer film with special treatment, produced by Ultimheat, ensuring a fast response, long life and high stability
FRAME: stainless steel.

MOUNTING: two M4 screws,28mm distance (European standard). The steel frame has also 2 holes dia 3mm allowing rear mounting SETTING: dia. 6mm shaft with a 4.6 flat, allowing the use of European standard knobs.

SHAFT ROTATION:270° mechanical rotation
ADJUSTMENT RANGE: 30 to 100%, clockwise set point increase
CALIBRATION: at mid angulation, at 42% relative humidity and 22°C  ambience. Calibration point accuracy: + / -5% relative humidity.

CONTACT: SPDT, silver contacts. Can be used in humidification, dehumidification or ventilation ELECTRICAL RATING: 5A 250VAC, res.

ELECTRICAL CONNECTION:
• Connection block for wires up to 2.5mm²
• Simplified version with micro-switch connection tabs 2.8 x 0.5 (MOQ apply)
AMBIENT:
• Ambient temperature: 5 to 85°C
• Humidity: 5 to 95% (non condensing)
• Air velocity: 15m /s max
PRECAUTIONS FOR USE: This product is not intended for applications with voltages above 48V when there is a risk of condensation. OPTIONS: Special rotation and humidity span, clockwise set point increase, special shaft diameter or length, gold plated contacts (MOQ and / or tooling costs apply)
MAINTENANCE: No maintenance required in applications in dust free clean air. Solvent vapors, spray, aerosol, fume may contaminate the film and make it insensitive to humidity. Dust deposits increase response time and can be removed by smooth air spray.
