Introduction:

AC802 Series digital thermostats are widely used for temperature controlling of blower fan scroll, electronic valve, electronic fan valve, electronic wind gate and equipment that supply heating. It adopts special large liquid-crystal screen, by the inside temperature sensor of NTC (negative temperature coefficient), compared with the indoor measured temperature and the set temperature, automatic adjusts the inflowing cold air and hot air and opens and closes the electronic valve, and achieves the goal of keeping constant temperature between indoors and outdoors.

Characteristic:

◆ Chinese edition LCD display, home electrical appliances operating surface.
◆ the indoor temperature precision resolving power is 0.5 ℃.
◆ 8 hours timely open/close power
◆ the wind speed in four types of working status : high, middle, low and automatic.
◆ super thin, subminiature design (surface board only 12mm thick).
◆the output control of the relay is stable.
◆ the air blower in four kind of working status: high, middle, low and automatic.
◆ indoor temperature adjustable and compensatory function (realized by the buttons of surface board directly).
◆ data memory function, if the power suddenly shut off, it can restored the work after the electricity come back.

Function:

It controls blower fan scroll and two-way valves temperature, when temperature arrives, the valve and blower fan scroll stop simultaneously; It controls electronic wind valve and electronic wind gate; It controls blower fan scroll and two-way valve, when temperature arrives, it only closes two-way valve; It controls three-line electronic wind valve and controllable device.

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 measure and control 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 l(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 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*14.
