BF-8805A Temperature Controller

BF-8805A is widely used to control the process in which a heat-pump unit produces constant-temperature hot water by transferring it from small heating tank A (buffer tank) to large hot-water storage tank B.The controller continuously controls the supply of hot water at a suitable temperature from tank A to tank B until tank B is full, while keeping tank B's water temperature within the set range.

BF-8805A is also commonly used for intelligent control of gradual water-volume and temperature increases in heat-pump tanks, and for collecting hot water at the set temperature from solar collectors into a storage tank.Built-in temperature control, can be used exclusively for heating control.

The switching power supply ensures stable, reliable, and durable controller operation across an AC 80V～240V supply range.

• One 240K NTC temperature sensor input; the sensor cable can be extended up to 100 m

• One water level sensor input detects 0%, 30%, 50%, 80%, and 100% water levels

• The first normally open and normally closed contact output can control the heating

• The second normally open contact output controls the constant temperature of the water.

• Low water compulsory loading

• Temperature controlled heating

• Temperature measurement deviation correction

• Setting parameters Power down Long-term memory retention
