AVT2805 A

New version of the central heating furnace controller using the ATMEGA8 processor. The system supervises the operation of the hot water pump and the furnace fan. In addition to normal operation, overheating of the furnace is signaled, the system also supervises the function of blows. With the ease of use it is offered to automatically turn off the controller (after a certain time - when the pump and fan are not working) and the ability to adjust the brightness of the LCD backlight.

The device is particularly recommended where it is necessary to control the temperature outside and inside the house

Selected parameters:

• continuous temperature measurement combined with heating pump and furnace fan operation
• two temperature measurement channels
• presentation of the operating mode - alphanumeric LCD display
• system control - microswitches
• sound and light signaling (LED diodes)
• executive elements - relays
• power supply - 230 Vac
• 2 printed circuit boards and documentation included
