The SAT sensor is shipped attached to a small bracket. If the HVAC unit has an upper block off panel, attach the sensor / bracket as shown in Fig. 8A using a 10 x 5/8” selfdrilling screw. If the unit does not have an upper block off panel, remove the bracket from the SAT and screw the SAT to the side of the indoor blower, using a 10 x

Look on the back of your unit, and you’ll find the model number listed on a silver series ratingplate located above the service valve connections. If your heat pump is geothermal, the model information should be easily found on the front of the unit. Gas or oil furnace. Remove the front door and look inside the unit.

If yes continue to the next step, If no replace the RTEM and jump to end. 3. It looks like you do have a CO2 sensor installed. Check DC voltage across the two DCV pins (with wires still attached). If you measure 0VDC (short) or 10VDC (open) then you should verify proper wiring. If wiring is correct then replace the CO2 sensor.

The following instructions are provided to assist you in developing this CO2 sensor unit that can: Measure the CO2 levels in the air. Record CO2 at regular intervals (store a value and timestamp). Display the current CO2 level being measured, as well as: temperature, air pressure and humidity through our IoT platform “Wappsto” through a wapp.

May 13, 2015· Lennox RTU with Prodigy controller. Stand alone, no BMS. Space needs temp, humidity and CO2 sensors. I''d like to do this with a single sensor instead of 2 or 3. The LConnect communicating zone sensor will do this, but according to Lennox tech support, you can''t use the sensor to control a standalone unit, even though the data sheet says you can.

sensor. Over time the sensor will lose sensitivity, and will need to be replaced with a new System Sensor carbon monoxide detector. This detector’s lifespan is approximately six years from the date of manufacture. Periodically check the detector’s replacement date.
