Route the wire through the back of the Temperature Sensor and connect it as
shown in Figure 83 below. Pull the wire through the back of the box until a drip
loop is formed as shown.
Static Pressure (SP) Wiring
There is a Static Pressure Sensor included with every Chore-Tronics
®
2 Control. This
sensor is pre-wired from the factory to Analog Input #4 (AI 4) (Figure 84). If it is
desired, the Static Pressure Sensor can be wired to any of the Analog Inputs (AI1
through AI12) (See Figure 85 for example wired to AI2). 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.
