Point Name – Description Default/Range
Leaving Water Temperature
Leaving Water Temp Setpoint
– The leaving water temperature setpoint maintained by the module.
D: 44°F
R: 15 to 75°F
Leaving Water Temp Setpoint Offset – An offset value that allows for adjusting the leaving water
temperature setpoint received by the System Control Setpoint or written by a Third Party.
D: 0°F
R: -5 to 5°F
Leaving Water Temp Bypass Setpoint – The number of degrees that the leaving water temperature must
drop below setpoint to enable modulation of the module’s bypass valve.
D: 2°F
R: 0 to 5°F
Outdoor Air Temperature
Outdoor Air Temp Setpoint
– The outdoor air temperature below which the module is allowed to operate. D: 50°F
R: -20 to 80°F
OAT Offset Setpoint – The number of degrees that the outdoor air temperature must rise above setpoint
to disable the module’s operation.
D: 3°F
R: 1 to 10°F
Cooling Demand Limit
Demand Level 1 Cool Adj – The leaving water temperature setpoint is increased by this number of
degrees when receiving a Demand Level 1 signal.
D: 1°F
R: 0 to 10°F
Demand Level 2 Cool Adj – The leaving water temperature setpoint is increased by this number of
degrees when receiving a Demand Level 2 signal.
D: 2°F
R: 0 to 10°F
Demand Level 3 Cool Adj – The leaving water temperature setpoint is increased by this number of
degrees when receiving a Demand Level 3 signal.
D: 3°F
R: 0 to 10°F
Point Name – Description Default/Range
Leaving Water Temperature Alarm
Low Leaving Water Temp Alarm Limit – The Leaving Water Temp must drop below this value to
generate a Leaving Water Temperature Alarm . There is a fixed hysteresis of 2  °F for return to normal.
NOTE : This value should be set to at least 4°F below the configured leaving water temperature setpoint.
D: 42°F
R: -45 to 45°F
High Leaving Water Temp Alarm Limit – The Leaving Water Temp must rise above this value to
generate a Leaving Water Temperature Alarm . There is a fixed hysteresis of 2

°F for return to normal.
NOTE : This value should be set to at least 10°F above the configured leaving water temperature setpoint.
D: 125°F
R: -20 to 150°F
Entering Water Temperature Alarm
Low Entering Water Temp Alarm Limit – The Entering Load Water Temp must drop below this value to
generate an Entering Water Temperature Alarm . There is a fixed hysteresis of 2

°F for return to normal.
D: 42°F
R: -45 to 45°F
High Entering Water Temp Alarm Limit – The Entering Load Water Temp must rise above this value to
generate an Entering Water Temperature Alarm . There is a fixed hysteresis of 2  °F for return to normal.
D: 125°F
R: 90 to 150°F
Outdoor Air Temperature Alarm
Low Outdoor Air Temp Alarm Limit – The Outdoor Air Temperature must drop below this value to
generate an Outdoor Air Temperature Alarm . There is a fixed hysteresis of 1  °F for return to normal.
D: -65°F
R: -65 to 40°F
High Outdoor Air Temp Alarm Limit – The Outdoor Air Temperature must rise above this value to
generate an Outdoor Air Temperature Alarm . There is a fixed hysteresis of 1

°F for return to normal.
D: 245°F
R: 100 to 245°F
