1.
With factory-installed ifm efector flow-sensing
devices, a secondary field-provided flow-sensing
device is optional. When a secondary flow-sensing
device is used, rem ove the factory jum per, and install
its contacts betw een 1X1-5 to 1K27-4; this places the
secondary flow sensing device in series w ith the
ifm efector.
2. For field-provided prim ary proof of flow devices,
connect the prim ary proof of flow device betw een
term inals 1X1-6 to 1K16-J2-2. The secondary field
provided flow sensing device is optional; how ever,
w hen it is present, it m ust be field-w ired in series w ith
the prim ary proof of flow device.
Temperature Sensor Circuits
All tem perature sensors are factory installed except the
optional outdoor air tem perature sensor (refer to
Figure 33, p. 65
for sensor locations). This sensor is
required for the outdoor air tem perature type of chilled
water reset. Use the follow ing guidelines to locate and
m ount the outdoor air tem perature sensor. M ount the
sensor probe w here needed, how ever, m ount the sensor
m odule in the control panel.
