Fig. 19 — Cooling Set Point (4 to 20 mA)
Cooling Set Point (4 to 20 mA) —
based on an external 4 to 20 mA signal input to the Energy
Management Module (EMM). The signal is connected to
TB6-3,5 (+,–). Figure 19 shows how the 4 to 20 mA signal is
linearly calculated on an overall 10 F to 80 F for both Water
and Medium Temperature Brine COOLER FLUID configura-
tions. See Table 30 for configuration instructions.
