    This cyclic controller is an independent climatic control unit allowing greenhouse vent opening/closing, heating system start/stop as well as an alarm contact.

    Greenhouse vent(s) opening/closing

     

    Allows greenhouse vent opening and closing in timed cycles to reach a target.

     

    For example, by introducing the following parameters:

    • 25°C opening target
    • 23°C closing target

    If the temperature exceeds 25°C: opening will be operated according to a timed cycle
    (eg 3 SECONDS opening and 5 MINUTES waiting).
    If the temperature drops below 23°C: opening will close according to a timed cycle
    (eg 8 SECONDS closing for 3 MINUTES waiting).
    If the temperature falls between 25°C and 23°C: opening will remain stationary. Which means that the temperature of the greenhouse is between these two points.

    Closing and opening times can be adjusted separately (example: in winter, open slowly and close quickly).

    In addition, for more control, opening size (ex: not to open too big in the spring), vent limit switch can be manually adjusted.

    Vent opening/closing can also be done manually with the controller.

     


    Heating system start/stop

     

    On/Off heating unit can be operated by this controller. The setting allows you to choose a target heating temperature and a temperature hysteresis.

     

    Heating hysteresis is the difference between the on and off temperature. It is usually set at 1°C. Example: for a set temperature at 18°C, the heating will turn on at 18°C and turn off at 19°C.

     

     

    Alarm

     

    Alarm contact (12 VDC) signal is activated by several conditions:
    - too low greenhouse temperature
    - too high in the greenhouse temperature
    - power failure
