Q. What causes my thermostat to short cycle?

Q. Why does my zone valve let flow through it when it is not powered?

Q. The installation in question has zoned hydronic heat, controlled with 3 Taco 571 zone valves and 3 Taco 568 thermostats. I need to replace one of the thermostats, but Taco no longer makes the 568. Are the newer thermostats with no heat anticipators compatible with Taco zone valves? The instructions with the 571 valve say that the thermostat heat anticipator must be set to 0.9A to match the valve rating. Will the valve function correctly without a heat anticipator in the zone?
