Flow Switch Control
A paddle flow switch is installed into the water pipe work of the unit to warn of low water flow within the system.
The flow switch limitations are as follows:
Flow switch setpoint
Setpoint increasing flow "ON"
Setpoint decreasing flow "OFF'"
After 5 retries of start-up of pump, with the paddle flow switch, which stays opened, the alarm 32 activates.
