663 s QAX95.4 QAX96.4 QAX97.4 QAX98.4 Wireless and battery-less room units with EnOcean interface QAX95.4 QAX96.4 QAX97.4 QAX98.4 Usable with devices from the following ranges: – RXC (together with gateway EnOcean/LONW ORKS, RXZ95.1/LON) – RXB (together with gateway EnOcean/KNX, RXZ97.
Specially suited for • Renovation projects (old buildings, museums, churches, historical buildings, etc.). • Rooms where wall reworking is difficult or even impossible (sandstone, glass, metal) • Spaces requiring adjustable room division (open plan offices, museums, TV studios) • Rooms with flexible furnishing or frequently changing decor • System extensions Use The wireless room units are used to acquire the room temperature and, with the exception of QAX95.4, adjust the room temperature setpoint.

Installation notes – For authorized personnel only STOP Caution! • Only authorized personnel may connect and service the device. • The device is designed for mounting in closed, dry, and bright rooms. • The device features an integrated antenna. Metal walls or furniture may not interfere with the radio signal. • Do not mount on a metallic surface, as this interferes with radio signal transmission. Minimum distance: 20 mm.
Mounting You do not need to open the device for mounting. Claws Mounting plate Frame Wall mounting The mounting plate is asymmetric! Make sure the claws are located on the sides. • Attach the mounting plate to the wall. • Place the frame on top. • The sensor can now easily snapped onto the mounting plate claws. Mounting on glass surfaces An adhesive pad (71 x 71 mm) is provided for mounting on glass surfaces. In addition to secure placing, this ensures visual protection for the device rear.
Function The room device determines the current room temperature and rotary knob position and transmits them via radio interface as soon as the energy store is sufficiently charged via the solar cell. A receiver (gateway) receives the data telegrams and routes them to a control unit. This type of cooperation requires that the receiver "trained" the sender. See data sheet N1661 (Gateway EnOcean/LonWorks) or N1662 (Gateway EnOcean/KNX). Current room unit data are sent only every ca.
Lighting conditions at mounting location For guaranteed operation (without battery), at least 200 lux illuminance must be present for at least 3 to 4 hours daily. Avoid direct exposure to the sun, as this results in fault temperature readings. Avoid also shading by furniture as well as mounting in wall recesses without sufficient lighting. Startup time at empty energy store: Ca. 1 min. at 400 lx Illumination time required to charge the empty energy store for 14 hours operation in total darkness: Ca.
Remove the battery Use a screwdriver no. 2 to remove the battery. Carefully insert the screwdriver between battery and battery holder contact and lift up the battery. Notes• Careless handling of the battery holder damages the holder. Proper and secure contacting of the battery may no longer be possible. • Do not try to remove the battery with your fingers. This may damager the battery holder and its attachment on the circuit board. Make sure you do not damage neighboring parts.
Engineering For operation, the connection to the gateway must first be set up. See data sheet N1661 (Gateway EnOcean / LonWorks) or N1662 (Gateway EnOcean / KNX). Commissioning Send "Init" telegrams The LEARN button is located on the lower section of the housing below the battery. Press this button to create and immediately send a complete learning telegram. The current switching status of LEARN – pressed – is also transmitted.
