LCC4 – Climate Control Computer

The LCC (Logic Climate Control) series from DGT by Senmatic offers extraordinary levels of control and precision, sufficient to run a major horticultural production enterprise, regardless of the required/desired grow-environment variables, with maximum efficiency. 

The LCC4 climate computer can control all climate functions for up to 16 different compartments. It is based on state-of-the-art technology and an advanced operating system and is easy to update and expand with more functions and capacity, futureproofing against business change or expansion. The LCC4 communicates via Ethernet with the installed expansions, and this ensures a great degree of flexibility in connection with future expansions.

The flexible composition of the hardware in the LCC4 makes it possible to choose sensors that are exactly optimal for each production system. It is also possible to use more than one of each sensor in each room, offering a level of flexibility sufficient to ensure the highest rates of accuracy and safety.

When developing LCC4, DGT by Senmatic’s primary focus was to achieve a simple user interface without compromising the setting options. Through collaboration with major growers, they have created a control system with extreme user-friendliness. LCC4 features a touch screen, which can be customised and individualised to ensure the computer interface is as simple and logical as possible for the grower.

 

 

Energy saving climate control

The LCC climate computer can divide 24 hours into 6 time zones with optional automatic correction, depending on sunset and sunrise. For the LCC4, DGT by Senmatic have developed a new Energy Balance Model. The model calculates the energy demand based on the K-factor of the greenhouse and the screens, the change-rate of air and the energy added by artificial lighting. The model ‘recognises’ the greenhouse and the energy demand, which ensures a better and more stable regulation also known as “feed forward regulation”.

 

Common and individual control

LCC4 can control up to 16 compartments and each compartment can be divided into two subzones, depending on the function. All functions can have common set points. It is also possible to have local set points in the subzones. These can be dependent or independent of the common set points. This gives a simpler operation of the computer and at the same time makes it possible to adapt the conditions to the different cultures.

With the LCC4, growers can control grow environment variables including internal climate and irrigation, as well as adjusting DGT by Senmatic’s LED fixtures, allowing dimming and spectral modification. Ventilation can also be controlled in greenhouse or suitable grow-room systems with cascade vent control. This system opens the lee side and the wind side at the same time. The wind side is opened only slightly, while the lee side is opened as much as needed. This cascade control of vents gives an effective ventilation in greenhouse environments, even at small vent opening percentages.

Weather station
One common weather station for the net of LCCs.
A weather station comes with wind direction and wind speed as standard. It can be expanded with a rain and light sensor.

Optional central control
LCC4 is a network model which communicates with SuperLink via Ethernet. SuperLink is used for further analysis of data

The use of more LCC4s
The LCC4 climate control can be used in many different installations, and more LCCs can be connected in a network.
