Control output
Refrigeration/heating:
Normal status:
HC=0, refrigeration mode:
When the cabinet temperature is higher than the set temp hysteresis
temperature, and finish the control load start delay time, the refrigeration will start
；
When the cabinet temperature is lower than the set temperature, the refrigeration will
close.
HC=1, heating mode:
When the cabinet temperature is lower than the set temperature, and finish the control
load start delay time, the heating will start: When the cabinet temperature is higher than
the set tempe hysteresis temperature, the heating will close.
Note: For the initial use of controller, the control output start delay time is calculated as 3s,
and in the future, it is calculated as C2(Control load start delay) In heating model, it needs
to set d1 to 0 (Defrost forbidden)
Sensor failure:
A2=0, the function of “Run/stop in a proportional time” is canceled, the control output
closes;
A2≠0, the function of “Run/stop in a proportional time” opens, the control output will run
and stop periodically according to the set time after the sensor fails.
Defrost:
If the defrost cycle is not 0, the controller will start defrost when it finishes defrost cycle or
it can be manually started. Defrost stops when finish defrost time or it could be manually
stopped.
Display during defrost:
d3=0: Display real time cabinet temperature
d3=1: Display dF during defrost
d3=2: Display defrost start temperature during defrost
