B713

The B713 pump intelligent controller is both an integrated intelligent controller designed to support pumps and an intelligent controller designed to achieve constant differential pressure control for central air-conditioning water circulation systems.
The B713 series can not only supply water at a constant pressure, but also has a differential constant pressure control. It has functions such as multi-pump linkage, one-use, one-standby time-slot water supply, multiple fault protection and self-starting when power on.

Product description

B713 series products are not only the integrated intelligent controller designed for water pump, but also the intelligent controller designed for the central air-conditioning water circulation system to realize the differential constant pressure control.


Features

l Suitable for various constant pressure/constant differential pressure water supply applications.

l After parameters were set correctly, the system can operate automatically with constant pressure or constant pressure difference according to the water consumption without manual operation;

l Stop running automatically when no water consumption;

l Alarm automatically when faults occurred;

l Alternate running automatically in the multiple pump system, prolong the using life of pumps.


Product advantages

◆ Multi-Pumps Control Function: Max.6 pump linkage water supply

◆ Sleep Function: Sleep down when have no water consumption, to earn a better energy saving

Cautions

WARNING: Wrong using may result in death or serious personal injury.

l Please don’t dismantle, change the product, or may cause electric shock, fire hazard and personal injury;

l Please don’t open the cover during the running of controller;

l  Please don’t put wire, bar of metal, filaments etc. into the controller so as not to cause a short circuit or get an electric shock;

l Please don’t splash water or other liquid over the controller. 


CAUTION: Wrong using may result in the damage of controller or system. 


Please don’t make withstand voltage testing for the controller;

Never connect AC power to output UVW terminals;

If the internal components of the controller were influenced or damaged by static, please do not to touch;

The motor, controller and power specifications should be matching, otherwise it could cause abnormal operation even burn out the device;

If the controller appears serious vibration, noise, heat or peculiar smell in the first operation, please cut off the power immediately and contact suppliers or service center later;

Please don’t install the controller in the environment with direct sunlight, rain, frost or snow in case of deformation or damage.
