Control Function
On/offline set
Keep depressed for 3 seconds to switch between online and offline. The controlling only works when online.
Ventilation Fan (R2) Control
When online, ventilation is on.
When offline, or door is open, ventilation stops.
Door Control (according to door switch S1, optional function)
Parameter U50 set the switch control mode:
Normal open: U50 = 1: When door is open, the door switch is open. When door is closed, the switch is short inside.
Normal close: U50 = 0: When door is closed, the door switch is short inside. When door is open, the switch is open.
Factory setting: U50 = 0. In this setting, if without a door switch, the controller thinks the door is closed always.
When door is just opened, the lamp will be on for U34 (under setting U30 = 0), even in offline status.
When door is just closed, the lamp will be off.
When door is open: heater and ventilation are off, egg tray stops. If U16 = 1, manual egg tray control is still effective.
When door is closed: heater can work, ventilation is on, egg tray can work automatically.
Temperature Control (R1, SSR)
R1 control (T10 = 0)
If room temperature ≤ (T11 - T12), and R1 has been stopped for T14, R1 will be energized.
If room temperature ≥ T11, R1 will be de-energized.
External SSR hysteresis control (T10 = 1)
If room temperature < T11, SSR will be energized.
If room temperature ≥ T11, SSR will be de-energized.
SSR power rate:
When room temperature < (T11 –T13), SSR output is full power rate.
When room temperature ≥ (T11 –T13), SSR output is: U93 * full power rate.
Example: if U93 = 50, the power rate is 50% of full power rate.
External SSR PID control (T10 = 2)
See paragraph Apendix: PID control
High temperature protection
Protection reaction could be R5, R4 or R8, depends on settings.
When room temperature ≥ (T11 + T25), start protecting.
When room temperature ≤ (T11 + T25 – T26), stop protecting.
Humidity Control (R3)
Humidify control (H10 = 1)
If room humidity ≤ (H20 – H21), and R3 has stopped for H23, R3 will be energized.
If room humidity ≥ H20, R3 will be de-energized.
Dehumidify control (H10 = 0)
If room humidity ≥ (H20 + H21), and R3 has stopped for H23, R3 will be energized.
If room humidity ≤ H20, R3 will be de-energized.
High humidity protection
Protection reaction could be R5, R4 or R8, depends on settings.
When room humidity ≥ (H20 + H26), start protecting.
When room humidity ≤ (H20 + H26 – T27), stop protecting.
Egg-turning Control (R6, R7)
Mode 0 (U16 = 0):
Either R6 or R7 will be energized, need position switches, manual turning does not work.
When left turning time (U11) arrives, R6 energized, R7 de-energized.
When right turning time (U13) arrives, R7 energized, R6 de-energized.
Mode 1 (U16 = 1):
R6 and R7 is not energized when no turning, manual turning works.
When left turning time (U11) arrives, R6 energized for U17.
When right turning time (U13) arrives, R7 energized for U17.
Manual turning:
Keep and depressed simultaneously for 3 second to enter into the mode, R6 and R7 will be
de-energized, the display will be flashing;
If keep depressed, R6 energized, displayed;
If keep depressed, R7 energized, displayed;
Keep and depressed simutaneously for 3 sec, or no key operation for 30 sec will exit the mode.
Egg turning times:
R6 starts once + R7 starts once = turning once. When egg turning times reaches U14, turning will not start any more.
If turning times (U14) = 0, turning will never stop.
