What does it mean if Chore-Time Chore-Tronics 3 Control Home Automation says that the pressure in the house is .00?
- JJames BrennanSep 9, 2025
If the control says that the pressure in the house is .00" and will not move, it indicates a wire connection problem between the static pressure monitor and the IO board. When the static pressure monitor is disconnected from the IO Board the Control defaults to a reading of .00. Check for wires being switched, broken wires, wires not making a good connection, etc. An easy way to remember the wiring is that the red wire is connected to the positive terminal of both the IO board and the static pressure monitor.
