T8100-NS/NSP Wiring Diagrams
The Ventostat T8100-NS and T8100-NSP family of products has two
basic configurations.
T8100-NS provides simultaneous voltage and current outputs for CO
an independent thermistor with Night Setback Override Button. The
button shorts the thermistor when depressed.
T8100-NSP provides simultaneous voltage and current outputs for CO
an independent thermistor with Night Setback Override Button and slide
Potentiometer that can be used to control thermostat set point. The slide
potentiometer has 0 KOhm value in the left position and 100 KOhm
value in the right position; the middle position corresponds to 50 KOhm
value.
The functional block diagram of T8100-NSP is presented in Figure 1.
The electrical circuits of thermistor, Night Setback Overage Button and
potentiometer have common signal between each other as shown in
Figure 1.
The electrical circuits of the CO
one side and thermistor, Night Setback Override Button and
Potentiometer from the other, are electrically isolated from each other.
For electrical wiring and power supply requirements, these two
configurations are identical. The recommended wire gauge is 18-22
AWG (1.0 to 0.75 metric).
!WARNING!
Ventostat T8100-NS/NSP products have two
terminal pins that are connected inside the sensor
to a common/ground: pin #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.
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-wire or loop-powered devices will
irreparably damage the sensors and void the
