Introduction:

AC803+ Series digital Temperature controller are widely used for temperature controlling of blower fan scroll, motorized valve, electronic fan valve, electronic wind gate and system that control temperature. 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.

Characteristic:

◆ Special large show of liquid crystal screen, blue or orange back-ground at free choice.
◆ The liquid crystal screen shows the temperature of the room and temperature hoped accurately at the same time.
◆ Adjustive and compensative function, implement directly through the thermostat’s panel button.
◆ time showing function, kinds of models at free choice.
◆ Possessing infrared remote control connection, choosing and matching remote controller control..
◆ it can be made program to control, which can set time for power switch 7 days in advance and has RS485 connection  

Function:

1, program temperature for a week, set time function, fixed time to open, to close machine (optional). 2, sleep function (optional), the room temperature is comfortable, economical and saving electricity.3, realize the common control, the long-distance control, the computer monitoring 4, If the power suddenly off, it can restored the data. 5, the air blower wind speed may automatic control, also may manual control. 6, Low temperature protection function (low temperature self-starting, frost (proof ).

Specification:

Three gear blower fan scroll wind speed, two-line electronic valves, the solenoid valve may concurrent open/close wind valve or three gear valves.

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.
