Table 5. Reset Option (Point 48). Value Description 0 No Chilled Water Reset (Default) 1 Return Chilled Water Reset. Constant Return Chilled Water Temperature Set Point maintained. 2 4 20 ma Chilled Water Reset. Resets Chilled Water Set Point based on 4 20 ma signal. A signal less than 4 ma results in no reset of Chilled Water Temperature Set Point. A signal greater than 4 ma results in a linear reset between Chilled Water Set Point and the Maximum Chilled Water Reset Set Point plus the Chilled Water Set Point. 3 Network Chilled Water Reset. Resets Chilled Water Set Point based on the network evaporator leaving temperature reset (Point 49). A signal of 0 100% results in a linear reset between the Chilled Water Set Point and the maximum Chilled Water Reset Set Point plus the Chilled Water Set Point. 4 Ice Chilled Water Reset. Resets the Chilled Water Set Point (typically 23 F) based upon a 4 20 ma Signal. A signal less than 4 ma results in no reset of Chilled Water Temperature Set Point. A signal greater than 4ma results in a Chilled Water Set Point equal to the set point plus the maximum Chilled Water Reset Set Point (typically 22 F).
