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 (GOLD LP/COMPACT) or under Functions/Flow (GOLD RX/PX/CX/SD, Version E/F). See the Operating & maintenance instructions. MIN 5xd h MIN 3xd h MIN 3xd h 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.

The sensor can be mounted on the side or top of the duct for vertical or horizontal air flow. If the ambient temperature varies radically, for example outdoors or in cold attics, insulate the sensor to protect it from the ambient air and prevent the formation of condensation inside the detector housing. To ensure satisfactory function, the sensor should be located at a distance, in the direction of airflow, that is equivalent to at least 3 x the hydraulic diameter of the duct upstream of the nearest source of disturbance in the ducting (see the examples of sources of disturbance). If it is located downstream of the nearest source of disturbance, its distance from this source should be equivalent to at least 5 x the hydraulic diameter of the ducting.

Point 2 • Measure the ventilation duct. • Cut the tube to an appropriate length, if needed. • The tube should penetrate 90% of the duct diameter into the duct. • Insert the end plug. IMPORTANT! The arrow on the plastic cover must point in the same direction as that of the air flowing through the duct. Do not cut this end! End plug. Point 3 • Slip the seal onto the tube. • Insert the tube in the bottom of the sensor housing. Point 5 Electrical installation. • Select 0-10 V operation by putting the jumper in the voltage position. • Connect the cables as shown on the wiring diagram. • Lock the tube in position by means of the stop screw.

The mounting bracket enables the detector to be installed on a duct having a diameter as small as 100 mm. The bracket is supplied completely flat. Point 7 • Fitting of cover. The bracket is easy to bend/form to fit on circular or flat duct surfaces. • Secure the cover. Do not drill any holes in the cover for signs etc. Holes will cause air leakages and seriously disturb the function of the sensor. Secure the legs of the bracket to the duct.
