New type:
This is one form of standard instrument with new type display, uses complete transparent LCD to display, with bicolor backlight, different color of backlight is lit in the different state.

Can be used for temperature control or refrigeration:
The circuit can be used for temperature control or refrigeration, suitable for quick switch between summer and winter, no need to switch control instrument.

Real time collect and measure max. value and measure the min. value:
Collect the measured max. value and measured min. value real time in working hours, view at any time by pressing the button. Refresh these two values formerly collected real time by the pressbutton and restart to collect the max. value and min. value of the next time period.

High and low limit control:
High limit value and low limit value can be set, when measurement display is more than or equal to high limit value, the relay will trip under the temperature control function, and the relay will engage under refrigeration function. When measurement display is less than low limit value, the relay will engage under the temperature control function, and the relay will trip under refrigeration function..--- these logic relations reversely with each other can be realized by simple switch of the user by the pressbutton.

Operation method:
1addend/max. button:
addend/max. button:
2subtrahend/min. button
In the normal display state, press subtrahend/min. button once, min. is displayed at the lower of the screen; the number displayed under it is the min. temperature in a period of time memorized by the instrument, press this button once again to resume normal display, at this time, high limit or low limit is displayed beside the max. that is just displayed.
3After watching the max. or min. value, be sure to press the corresponding button once again to resume normal display.
4the SET button
In the normal display state, press set button once, high limit will flash on the screen, press addend/max. button or subtrahend/min. button to adjust high limit value. Press set button once more, low limit will flash on the screen, press addend/max. button or subtrahend/min. button to adjust low limit value. Repress the set button once, temperature control will flash on the screen, if the user is to control the heating equipment, then repress set button once, and exit the set state, here, system has saved the set data just now. if the user is to control the refrigeration equipment, press refresh button when temperature control flashes on the screen, here, refrigeration will flash on the screen, repress the set button once to exit the set state.
The above is a whole setting process, if the setting is stopped midway, the characters that are flashing on the screen will resume to normal display after flashing for 10 seconds, and this setting is invalid.
5Refresh button:
In the normal display state, press refresh button once to refresh max. temperature and min. temperature memorized by the system.

The circuit are equipped with a main control output port (icon display: bulb 1), carry out logic judgment output according to the working mode of the circuit in the temperature control or refrigeration mode. Another port is in energy saving output state (icon display: bulb 2), it follows the main control output port, but always output according to the 1:1 relation when the main output port is carrying out output effectively. Every time period is 30S, especially suitable for controlling the intermittent electric equipment at night such as air conditioner etc.
