Telaire Ventostat T8041 CO2 Duct Probe Transmitter

Fits HVAC return-air CO₂ demand-controlled ventilation where you need a Telaire Ventostat T8041 duct probe with 0–2000 ppm NDIR sensing and 0–10 V analog output.

Key advantages

• Range — 0–2000 ppm CO₂
• Sensing — Absorption infrared (NDIR)
• Output — 0–10 V (T8041); T8041-5V option 0–5 V
• Calibration — ABC Logic automatic background calibration
• Install — ~4.09 in probe; 1½ in duct hole; 3.05×3.05 in junction box

Typical applications

• Return-air duct CO₂ for DCV.
• HVAC energy optimization with Ventostat probes.
• Sites standardizing on T8041/T8042 family.

Selection guide

• Output — 0–10 V vs 0–5 V option
• Sibling — T8042 if different I/O needed
• Duct — Hole size and probe length fit
• ABC Logic — Suitable occupied-space background yes/no

Common mistakes

• Mounting in supply instead of return when DCV expects return air.
• Disabling ABC Logic without a calibration plan.
• Wrong voltage option vs controller input.
