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.
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.
