Product Details

1. The characteristics of the gas oven intelligent control system
1. The temperature control accuracy is higher than the traditional liquid expansion temperature control system, which can reach within ± 8 ℃, and the temperature control range is 50 ~ 260 ℃ (according to customer requirements)
2. The operation and use method is the same as the traditional liquid expansion temperature control system, and the installation method is also the same.
3. Can be used with safer silicon nitride hot surface igniter
4. The service life of the electronic temperature control valve is 300,000 times
5. The life of the electronic control selection valve is 10000 times
6. The temperature probe uses NTC or PT100, the response speed is fast
7. The use cost of this system is low, far lower than the bimetal control valve, and this system can replace the bimetal control valve;
Resolved the bottleneck of parts procurement only in foreign countries, shorten the system procurement cycle

4. Introduction of important spare parts
1. Electronic control valve
1. Rotate counterclockwise to adjust to the fire row, you can choose the temperature control gear;
2. Rotate clockwise for the upper gear;
3. In the closed position, the knob must be pressed to rotate.
4. Temperature control range 50 ~ 260 ℃

2. Electronic Controller
1. Input voltage 110V 60HZ
2. The output voltage of the hot surface igniter is 110V
3. Indicator lamp output voltage 110V
4. Electronic temperature control valve output voltage 5V
5. Working environment temperature: -20 ~ 80 ℃

3. Electronic temperature control valve
1. Input voltage 5V;
2. Action current: about 500mA
2. Operating life 300,000 times;
3. Working environment temperature: -20 ~ 100 ℃
4. Import and export thread: 5/8 ”-18UNF

4.Silicon nitride high temperature hot surface igniter:
①. The input voltage is 110V, the power is on for about 17s, and the surface temperature of the igniter reaches 1200 ℃.
② Rated current (two options): 2.0 ~ 2.4a; 1.67~2.1A。
③ Nominal power: 280W; 230W。
④ Advantages: no power attenuation, good strength and not easy to break. Weakness: the heating current changes from high to low, which cannot be replaced with the mainstream models (bimetallic chip temperature control valve) in the current market. It must be used with special circuit board.

5. Operating instructions.
1. When the knob is closed, press down clockwise to open the upper fire row burner side. During the opening process, first start the hot surface igniter of the upper fire row. After the hot surface igniter heats up normally, electronic control The device then sends electricity to the solenoid valve to provide gas to the upper fire exhaust.
2. When the knob is off, press down counterclockwise to select the temperature corresponding gear, the electronic controller will select the gear as the target temperature according to the gear. If the actual temperature of the oven is lower than the target temperature, open the fire grill side (starting process and up) The principle of fire row is the same). Conversely, when the actual temperature of the oven is higher than the target temperature, the lower fire row is turned off on the side, but the hot surface igniter of the lower fire row is still working normally at this time, and the hot surface igniter of each gear selected counterclockwise will be turned on. It will be closed only when the file is OFF.
