Load Water (Entering) Temperature:
The controller will monitor the entering load water temperature which is located at entering side
of coil.
Alarms will be provided as follows:
Load High Temp: If the water temperature at the entering load side is greater than the cooling
setpoint plus a user definable amount (adj.), the factory default for this amount is 10°F.
Load Low Temp: If the water temperature at the entering load side is less than the heating
setpoint minus a user definable amount (adj.) the factory default for this amount is 10°F.
Load Sensor Failure: If the load water sensor is outside of normal operating limits, typically
produced by a wiring failure between the sensor and the controller.
Source Water (Leaving) Temperature:
The controller will monitor the leaving water temperature on the source which is located on the
source leaving side of coil.
Alarms will be provided as follows:
Leaving High Temp: If the leaving water temperature is greater than 135°F
Leaving Low Temp: If the leaving water is less than 35°F.
Leaving Sensor Failure: If leaving water sensor is outside of normal operating limits, typically
produced by a wiring failure between the sensor and the controller
