Bwd-ks temperature controller

        1. Setting key:

        (1) In the parameter setting state, press this key to write the setting parameter and enter the next parameter setting;

        (2) When "black box" records the inspection status, press this key to end the inspection record state and enter the normal working state;

        (3) Press this key to enter the normal working state when the function simulates the detection state.

        2. Fan / shift key:

        (1) During normal operation, press this key to switch on and off the fan manually;

        (2) In parameter setting status, press this key to change the setting flashing bit

        (3) It is invalid to press this key when "black box" records the check status.

        3. Increment / key:

        (1) In normal working state, press this key to switch / patrol display status;

        (2) When the parameter is in the setting state, press this key to increase the data of setting the flashing bit by 1;

        (3) When "black box" records the check status, pressing this key is invalid.

        4. Record key:

        (1) In normal operation, press this key to enter the "black box" record inspection status;

        (2) When the "black box" records the inspection status, press this key continuously to finish the inspection and enter the working status;

        (3) When the function is detected, press this key to input the analog temperature value into the temperature controller; (for false tripping, when the analog input temperature is greater than the set temperature value of the temperature gate, the temperature controller will not send out a trip signal, and the trip indicator light on the panel will be on.)

        (4) It is invalid to press this key when the parameter is set.

        (5) Silencing key: press this key to give an alarm signal (but when the trip signal is started, the internal buzzer will not give an alarm).

        (6) Sometimes, if the key is not pressed for more than 20 seconds, the thermostat will return to normal working state.
