Mounting and Wire Connection

u Notice the supply power voltage of the detector: 24VAC. Do not install the detector on voltages higher than marked on the detector. u Following step 1 to 4 in figure. 1 to remove the cover. First, prepare a flat head screwdriver and put it deep inside of the hole on the top of the transmitter housing following step 1.

Then slant the screwdriver and open the cover gently following step 2. Do not mount it near diffuser or any steam source, in direct sunlight. u Mount the wall plate first, dimensions see fig. 2. there are two dimensions available.

If there is mounting box, please follow step 5 to 8 in fig. 3; if there

’s no mounting box,

Connect wires to terminal strips (see figure 5), or you can put in the power adaptor to the

1 socket of the indicator instead of connecting terminal 1, 2. make sure wiring connection correct and secure. Following step 4 to step 1 in figure 1 to close the cover.

Important Instructions

1. Don ’t shake or hit the CO2 indicator/controller too much in shipment or in mounting to protect the internal infrared CO2 sensor from any damage and excursion of infrared receiver.

2. When a. First use CO2 transmitter, or b. Reuse CO2 transmitter after a long time unused or c. CO2 measurement is proved to be incorrect (by comparing with the measurement of other Tongdy ’s CO2 products, or put the transmitter outdoors and its measurement is away from the range of 350ppm~450ppm, which is the normal ambient CO2 level range.)

Then let ABC Logic

TM

Self Calibration System work as follows:

Keep the CO2 transmitter energized continuously for at least 2 days to let CO2 sensor ’s ABC Logic TM

self-calibration system operate properly. After more than 2 days ’ calibration, if the measurement (indicated by the analog output) of the

CO2 transmitter still exceeds over the accuracy, you need to let it self-calibrated for a longer time. Here ’s the typical

14-day calibration solution: During a 14-day period, place the CO2 transmitter twice in outdoors or unoccupied places

where CO2 level is around 400ppm. Each time let it be there for more than 4 hours and then check the CO2 measurement via the analog output. If the CO2 measurement is in its accuracy limit, it indicates the measurement is right.

Notice: a. Use of cellular telephones or radio transceivers with two feet of the sensor during calibration process could cause sensor interference, calibration errors and affect sensor accuracy. Please refrain from using these devices during sensor calibration.

b. When checking the analog output, please avoid breath out directly to the CO2 transmitter. It

’s better to connect the output terminals with the Extending Wires with length of more than 1 meter. When the CO2 transmitter becomes stable after more than 10 minutes turning-on, check the analog output through the extending wires. That

’s because people ’s breath influences CO2 level.
