Entering Water Temperature Sensor
The OE233 Entering Water Temperature Sensor must be wired as shown
in Figure 10 below for proper operation. The Entering Water Tempera-
ture Sensor is a 10K Type III thermistor sensor. The Entering Water
Temperature Sensor should be mounted in the entering water piping.
NOTE: For Dual Cabinet Units, mount the Entering Water
Temperature Sensor in an Entering Water Piping area that is
common to both SA Units.
