Some third-party materials are needed to install the switch external to the water source heat pump. We recommend the following to successfully install the Flow Proving Switch (Differential Pressure): 4 x ¼" flare nuts, 2 x ¼" copper tu (2-4' sections), 2 x ¼" male flare nuts (replaces the P/T plugs in the Bosch hose kits), and flaring tool.

These highly versatile differential pressure switches are ideal for pump control, pumping systems, waste water, HVAC/R and process 

The differential pressure sensor is wired into the variable speed pump control. In a differential pressure controlled system, we use these components to make sure our control head stays at its setpoint which in this case is 20 feet. At full design conditions, we have 1000 GPM at 100 feet of head (40'+40'+20').

In pump and compressor systems, the switch is activated when the fluid pressure goes below a set level. This starts the motor of the pump or compressor, which returns the system to normal levels. The switch does not deactivate instantly when the pressure goes above the set point. There is a form of hysteresis or differential that prevents

Setting the pressure switch. The pressure switch can either be adjusted simply for the pressure setting with a fixed differential, or it can be adjusted for both the pressure setting and the differential, depending on the model and the manufacturer of the pressure switch.A fixed differential is generally in the range of 0.8 to 1 bar when a pressure switch is purchased, and

Range & Differential Adjustment on a Water Pressure Control Switch The (LARGER) RANGE Adjustment nut The larger nut ( green arrow) on the larger spring in the pump pressure switch: changes cut-in AND cut-out simultaneously moving them both up (higher pressure) or down (lower pressure). This is the range adjustment nut. [Click to enlarge any image].

The FD113 is a differential pressure switch which is used for monitoring flow status across pumps, chillers etc. The unit has and adjustable setpoint with
