Chilled Water Valve
For Chilled Water Applications, the Modulating Cooling Signal(s) can
be confi gured for either a 0-10 VDC or 2-10 VDC output signal when
programming the controller. The output signal can also be confi gured
for either Direct Acting or Reverse Acting operation as required by your
application. This signal output would be connected to a Modulating
Chilled Water Valve.
See Figure 23 below for detailed wiring of a Chilled Water Valve.
Warning: It is very important to be certain that all wiring is
correct as shown in the wiring diagram below. Failure to observe the
correct polarity could result in damage to the Modulating Cooling
Device or the SA Expansion Module.

WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-to-
24VAC. Failure to observe polarity will result in damage to one or more of the
boards. Expansion Module must be wired in such a way that the expansion
module and the controller are always powered together. Loss of power to the
expansion module will cause the controller to become inoperative until power
is restored to the expansion module.
Note:
1.) For Chilled Water Applications,
the Modulating Cooling Device Used
Must Be Capable Of Accepting
Either A 0-10 VDC or 2-10 VDC
Input. The Modulating Cooling
Output Voltage Is User-Configurable
For These Voltages. This Voltage
Output Must Be Configured When
You Are Setting Up The SA
Controller’(s) Operating Parameters.
2.) The Modulating Cooling Device
Used On The SA Controller Must
Have (1) Relay Output Configured
In Order To Enable The Modulating
Cooling Device's Sequence. This
Relay Output Must Be Configured
When Setting Up The SA Controller
Operating Parameters.
