If you configured the system for Variable Speed Pumping with a
Pressure Sensor for proof of flow, the Loop Controller can send
a signal to all the Heat Pumps to open their Isolation Valves
whenever a Hi Limit Pressure is exceeded. If the Heat Pumps do
not control an Isolation Valve, then the only reaction is to
reduce the variable speed pump voltage signal. WHP Loop Setpoints

Open if PSI is Above
Hi Limit...: xxx PSI
Minimum Default Maximum
Hi Limit 1 PSI 50 PSI 50 PSI
The Thermister Type III Sensor readings can be calibrated.
Enter a Positive value to increase the reading or a Negative
value to decrease the reading. If no sensor is attached, the
calibration offset will still allow a value to be input and read for
diagnostic purposes.
