The electric clique uses to control the one of the systematical pipe of a central air-conditioning system and a heating system, and opens or closes, the goal warm for a control office is achieved. A stopcock is driven from the motor by which one tape is delayed simultaneousness, and a spring is reset. When when a valve doesn't function, I have that, and I always have to close the state and work, one offers a signal of a faction to a put thing, connects with an electric faction and makes movement of a power supply be exchanged from a warm controller, a valve is opened, the board spout where I enter a fan of water or hot water is frozen and a chill or a heating system is offered to purpose in the room; When an office achieves the warm and warm set value of the complained container, the complained capacity for which it's warm makes the electric faction go out, and a reset spring makes a valve close, and I cut by that and enter a flow of water of fan's board pipe. An electric faction can have the switch which combines choice and cooperates, and it's applied to control of other equipment; Though it's different, it's chosen, and it's possible to use the form as a requisition is managed, and to apply the voltage, and it's filled, is different in TASU and is necessary.

The operation is flexible and can trust, and strong, and the noise of work is low, and it's possible to arrive at a board tract's of the fan of a ceremony who receives and hides always showing by the environment of the hot high humidity while establishing.    www.baiyunpv.com   021-62775279
