Differential Capacitance Pressure Sensor Circuit
Pressure Sensor Circuit. One capacitor is charged positive with respect to ground, while the other is charged negative with respect to ground, as the AC voltage source alternates positive and negative. While one capacitor of the pressure sensor is charging, the other is discharging through Rload, producing an output voltage (Vout).

Use a pressure relief valve. In addition to pressure regulating valve and pressure gauges, always install a pressure relief valve. This can also be a frangible disc type pressure relief device. This device should have a discharge port of at least ½" MPT size. The valve or frangible disc device must be set to release at 175 psig (see Figure 7).
Pressure Independent balancing Control Valves (PICV)
This continuously causes flow and differential pressure changes. Without proper measurements, such systems suffer from uneven heat distribution, poor energy inefficiency and are very difficult to commission. To avoid these issues Pressure Independent balancing and Control Valves (PICV) provide the best and simplest solution.

Taco still offers a thermostat #568-20. It may not look like your original, but it functions the same. Many people mistakenly think the 571 zone valve is a 3-wire zone valve because it has 3 terminals. All the Taco 500 series zone valves are 2-wire, 3-terminal zone valves. The heat anticipator has no bearing on the operation of the zone valve.
