GB.ELQZ504480.110202 Installation Instructions for theELQZ-2-504 Air Quality Sensor GOLD/COMPACT 1. General The carbon dioxide content of the indoor air is an effective indicator of how many occupants are in a room and the degree of ventilation required to maintain the air quality we need. Ventilation control based on CO2 measurements guarantee the adequate supply of fresh air, and at the same time keeps energy costs as low as possible. 2. Function Demand Control Set the air handling unit to “DEMAND REGULATION” under the “FAN REGULATION” (CONTROL) function menu (see the Operation and Maintenance Instructions). Set the setpoint required as a percentage of the sensor’s operating range. If a setpoint of 1000 ppm is required, for instance, set the setpoint to 50%. Enter the setting under the “FLOW/ PRESSURE” menu group (see the Operation and Maintenance Instructions). 3. Push the intermediate plate together with cover upward and hold firmly against the base plate. ReCO2 Set the GOLD unit to ”CO2” under the ”ReCO2” Function menu (see the Operation and Maintenance Instructions). Set the setpoint required as a percentage of the sensor’s operating range. If a setpoint of 1000 ppm is required, for instance, set the setpoint to 50%. Enter the setting under the “FLOW/ PRESSURE” menu group (see the Operation and Maintenance Instructions). 3. Mounting Locate the sensor where the indoor climatic conditions are typical for the premises. Avoid any spot where the sensor would be exposed to direct draught or poor air mixture. We advise locating the sensor at least 2 metres above the floor to minimize the risk of physical damage or inaccurate readings due to direct exposure to exhaled air. Access to the sensor is needed for checking its function and servicing only. 1. Route the cable to where the sensor is to be located. The cable can be recessed in the wall or other surface and should then be passed into the air quality sensor through its bottom section. If the wire is surface-mounted, it can be passed into the sensor through one of the knockout lead-throughs in the top of the sensor. 2. Back off the screw and pull the top section straight upward. Specifications are subject to alteration without notice. 4. Bend the intermediate plate with cover obliquely outward and detach it from the hooks. 1 1 1 www.swegon.com 1 GB.ELQZ504480.110202 5. Secure the base plate by means of screws to the wall. The screw head should be max. 4 mm. 6. A Insert the hooks into the holes in the upper section of the base plate. B Press the front against the base plate until its hooks lock into the bottom edge of the front. 4.
