Static Pressure (SP) Wiring
There is a Static Pressure Sensor included with every Chore-Tronics
®
3 Control. This sensor is pre-wired
from the factory to Analog Input #4 (AI 4) (Figure 22). If it is desired, the Static Pressure Sensor can be
wired to any of the Analog Inputs (AI1 through AI16) (See Figure 23 for example wired to AI1). Please
note that the Red wire must always be connected to the +24 volt terminal, the Blue wire must be connected
to the AI terminal being used and the Black wire must be connected to the ground terminal of the analog
Input being use. Make sure that whichever AI Input the SP sensor is connected to, that the blue jumper
above the Input is set to "U" position as shown.
