Ventostat Wiring Diagrams
The Ventostat family of products has two basic configurations. One
configuration provides three active outputs (CO2, RH and temperature)
and an independent thermistor. It has an output terminal block with pins
#1, 2 and 3. The other configuration provides only CO2 outputs and an
independent thermistor and has no terminal block with pins 1, 2, and 3
installed. For electrical wiring and power supply requirements, these two
configurations are identical; please follow the specific instructions for
wiring. The recommended wire gauge is 18-22 AWG (1.0 to 0.75
metric).
!WARNING!
Ventostat products have three terminal pins that are
connected inside the sensor to a common/ground: pin
#2, 5 and 7 on the I/O terminal blocks and pin #2 on the
power block. Do NOT connect positive (hot) 24 VAC power
line to terminal number 2 of the terminal block.
Caution!
The T8100 Ventostats are either 3-wire or 4-wire type
configurations, powered by either AC or DC voltage. They
are not 2-wire or loop-powered devices. Wiring the units as
2-wireorloop-powereddeviceswillirreparablydamage the
sensors and void the warranty.
Note: For temperature measurements, Ventostat models contain a
passive thermistor (terminal pins #4 and 5), which is
electrically isolated from the other circuitry and should be
wired independently from active CO2/RH/temperature outputs.
The thermistor has no connection to the Ventostat common
ground and/or power.
The active temperature output has the same common (ground)
as CO2 and RH outputs.

ABC Logic™ Self Calibration System
ABC Logic™ (Automatic Background Calibration) self calibration
allows the sensor to continually recalibrate itself when the indoor
concentrations drop to outside levels while the building is unoccupied.
Generally a building must be regularly unoccupied for 4 hours or more
for this self-calibration system to operate properly. Under these
conditions, ABC Logic™ should maintain sensor calibration over the
lifetime of the sensor. The ABC Logic™ should be turned OFF where a
building is continuously occupied 24 hours per day, or where there could
be significant sources of non-occupant related CO2 such as greenhouses,
breweries and other industrial and food processing applications.
