End Switch. When the end switch activates the circulator, the circulator transports hot water throughout the zone. When the heat reaches the desired level, the thermostat stops power to the zone valve and the system shuts down.

Beside this, what does a zone valve do?
A zone valve is a specific type of valve used to control the flow of water or steam in a hydronic heating or cooling system.
Furthermore, what happens when a zone valve fails? The zone valve opens and closes according to the temperature in the room as determined by the thermostat and your settings. Sometimes the zone valve will fail to operate properly. This can be caused by a malfunctioning part on the valve itself or by a faulty thermostat or a faulty connection between the two.
Correspondingly, what is end switch?
An end switch is usually a " dry contact switch" meaning no voltage from the control is applied. It is just a switch and you can control 24 volt or 120 volt or a DC volt circuit. So an end switch makes when something else happens first, like the zone valve opens or a relay closes.
Can you leave zone valve open?
Leave the zone valve in the manual open position and it will get heat when any of the other zones call for heat. Some zone motors do have end switches that stop them in either the open or closed positions but these will have a three-wire control.
Related Question AnswersWhere is the zone valve located?
Location of Zone Valves A zone valve can be located right after the boiler and circulator (hot side), or at the end of the zone circuit (cold side). If able, it is recommended to locate the valve on the cold side as it will be less damaging to the valve and improve its life-time.How long should a zone valve last?
It is only crucially important for a Taco zone valve. The system pressure is fine too so leave that alone. Those valves should last much longer than 2 years.How much does it cost to replace a zone valve?

If there is resistance there is water flow going to the valve, if the lever moves with no resistance then the problem is with the water line (such as a leak or lack of boiler pressure) and not the TacoHow does a 3 way zone valve work?
A 3-way zone valve is a bypass version of a 2-way zone valve with 3 ports, commonly used with fan coils, heating units or other central heating equipment. When it is required to bypass the equipment, the supply port of the valve is closed (automatically or manually) and the water flows though the bypass port.What is a taco valve?
The Taco zone-valve is an electricity operated valve used for zone control of hydronic heating and/or cooling systems. It controls the flow of water in a room or zone in response to the demands of the room or zone thermostat.
