All the LED indicators and nixie tubes (D1, Da, Month, Day) will flash after the controller is
powered on in 3 seconds.
Temperature Calibration Adjust A4 and A5 for calibration if the displayed room/water
temperature deviates.
Power-on Cooling
When Power-on Delay (A2) elapses, the controller will enter 100% power cooling for 30
seconds, and then operates according to actual room and water temperature.
Note: After power-on cooling, if water temperature goes above the value water
temperature set-point minus heating differential, the compress will not be switched off. This
function is designed for maintenance.
