It is the digital units that either steal power, need the resistor, direct power, or battery. All of the battery operated thermostats will work with the resistor and the units that require a third wire (C) to get power from the transformer. A lot of the new thermostats do not require a heat anticipator. Flo-Chek open automatically when the circulator starts running. This makes it possible to use the heating boiler to maintain domestic hot water year-round. However this design is ideal,making this out of thick metal pipe with welded caps and brazed fittings will. The current draw of the circuit had to be matched to the heat anticipator so it would work properly. Taco Flo-Chek prevents gravity circulation in forced hot water heating systems during periods when the boiler is hot, but the space heating zone is not wanted. Best for small projects,air and water pumps,fountains,anything small with low pressure. Its purpose is to trick the thermostat into shutting off ahead of time, allowing the heat left in the piping system to dissipate into the room and not overshoot the temperature setting.

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. Many people mistakenly think the 571 zone valve is a 3-wire zone valve because it has 3 terminals. It may not look like your original, but it functions the same.
