Description:
1、if you set up the start temperature higher than the stop temperature, then when the measured temperature up to start temperature , it work normally, when the measured temperature low to stop temperature, it stop work.
2、 if you set up the start temperature lower than the stop temperature, when the measured temperature low to start temperature , it work normally, when the measured temperature higher than the shop temperature, it stop work.
This product USE the advanced single chip microcomputer controller, simple operation, high intelligent degree. This controller can according to the temperature set by the user automatically open and close all sorts of power supply of electric equipment , especially suitable for control of the water heating, floor heating circulation pump, can also be used in other automatic temperature control.
Features:
Easy installation, without changing the plumbing, floor heating, electric heating
USES the microcomputer chip, high integration, digital programming, control precision, strong anti-interference ability;
Start, stop temperature, set respectively, display respectively, easy to read, simple for operation and quick test;
And adopts the new type of temperature sensor, responsive, high precision, the sensor can be based on user need to connect, does not affect the precision .
Have freeze protection function, when the boiler water to below 3 degrees Celsius, mandatory start circulating pump, prevent freezing pipes. With Over temperature alarming function. Such as system inner loop water temperature over 90 ℃, temperature controller and the digital tube twinkle ringing, prompting the user to handle in time.
