Cooling Set Point (4 to 20 mA) — A field supplied and generated, externally powered 4 to 20 mA signal can be used to provide the leaving fluid temperature set point. Connect the signal to TB6-3,5 (+,–). See Table 27 for instructions to

enable the function. Figure 22 shows how the 4 to 20 mA sig- nal is linearly calculated on an overall 10 F to 80 F range for fluid types (Configuration mode, sub-mode OPT1, item FLUD) 1 or 2.
