Introduction:
AC-808 Series digital temperature controller are widely used for temperature controlling for blower fan scroll, electronic valve, electronic fan valve, electronic wind gate, and temperature controlling device of central air –condition heating and air conditioning system. They adopt the special large liquid crystal screen. Through the inside temperature sensor of NTC (negative temperature coefficient), compared with the indoor measured temperature and the set temperature, they are automatic adjust the inflowing cold air and hot air and open and close the electronic valve, and achieve the goal of keeping constant temperature between indoors and outdoors. |

Function:
Control blower fan scroll and electronic valve, electronic wind valve and electronic wind gate, three-line electronic valve,
three-line electronic wind valve.
Installing instruction:
1. Thermostats must vertical install in air conditioning room and the wall of room must have good ventilative condition. The distance of thermostats and the ground is about 1.5M high, so that the thermostats can accurately measures and controls the room temperature. 2. Thermostats must be set far away from the doors or windows that light can penetrate directly, or heat source like cooking equipment or other heat source. 3. The thermostats’ drive board (power board) must be connected with blower fan scroll (electronic valve or wind valve) and power line according to the picture .4. when the front of the liquid-crystal board is taken off , made the power board inlay in the hidden box. 5. use the screw to fix the back cover tightly. 6. Make the surface board plug in back cover. 7. The matched line box is the entry wall type, the size is 86*86*13.
