Crop Management Technologies
INTRODUCTION
NMC Pro Climate is a climate controller that enables the user to control climate conditions,
setting them to the required level inside the climate zone (see zone explanation).
NMC Pro Climate controls up to four climate zones in a single controller.
In each zone, there is the option of controlling various climate systems such as:
•Vents
•Shading & Energy Screens
•Heating
•Misting
•Fan & Pad
•Air Circulation
•CO2
•Crop Protection
•Lights
Strong relationships and priorities are defined between the different control systems to
achieve maximum efficiency. Different influences (humidity, radiation, and temperature)
can be set to achieve maximum accuracy.
NMC Pro Climate has powerful communication capabilities between remote terminal units
and other controllers in the network, reducing cable costs and avoiding duplications through
receiving information from other controllers.
To maintain the same simplicity and user friendliness, the user interface has been kept as
similar as possible to the NMC Pro Irrigation.
CLIMATE ZONES
Climate zones are independent climate areas (covered and closed) which are used as
references for the climate control. Usually climate zones represent one greenhouse but in
some cases one greenhouse can be divided into four climate zones.
The reference sensor/s of each specific zone is the attached measuring box/es (Temp &
Humidity).
•Define any or all nine climate control systems inside the climate zone/s.
•Define up to four climate zones within the NMC Pro Climate controller.
The entire viewing structure and navigation throughout the user interface is based on the
climate zone/s.

*VPD is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated. Once air becomes
saturated water will condense out to form clouds, dew or films of water over leaves.

VENT
PROGRAM –VENT (MENU 1.1)
The goal of the Ventilation process is to maintain a fixed temperature in the green house.
The Ventilation control manages the vents operation according to the conditions of the
greenhouse.
The monitoring and operation is done per control (1-3) and within the control number the
controller should operate the vent individually. There are several inputs that influence the
calculation position of the vents, such as: inside and outside temperature, humidity, wind
speed, wind direction, radiation and rain.
Emergency cases like rain, storm or frost are monitored continuously and during such events
the controller reacts according to the configuration. The vent control should operate in
cooperation with other controls like fan & pad, screens, etc.
The vent types (top, side) are divided into vent controls. Each vent control includes lee side
and wind side.
•Wind side –The side that the wind enters the greenhouse.
•Lee side – The side opposite the direction of the wind.

Temperature
Define the temperature set point for top
ventilation. If the measured temperature is
above the set point, the top ventilation begins to
open.
0o to +50o C 20
5.
Side Ventilation
Temperature
Define the temperature set point for side
ventilation. If the measured temperature is
above the set point, the side ventilation begins
to open.
0o to +50o C 20
6.
Radiation
Influence
Define the conversion table that indicates the
influence of the radiation level outside on the
ventilation temperature.
*See Solar Radiation Influence below
0 - 2500 W/m2
-50o to +50o C 0
7.
Humidity
Influence
Define the conversion table that indicates the
influence of the humidity level inside on the
ventilation temperature.
*See Humidity Influence below
0 - 100 %
-50o to +50o C 0

Wind Influence
Define the conversion table that indicates the
influence of the wind speed level outside on the
ventilation temperature.
*See Wind Speed Influence below
0-50 m/sec 0
9.
Cool Down
Define the gradual cooling down time per 1oC
(approximately 2F). This is used to avoid fast
changes between periods.
*
For example: Setting this parameter to 15
minutes (00:15) means that it will take one hour
for the zone to cool down from 24°C to 20°C (15
minutes per 1°C).

Heat up
Define the gradual heating time per 1oC
(approximately 2F). This is used to avoid fast
changes between periods.
*
For example: Setting this parameter to 15
minutes (00:15) means that it will take one hour
for the zone to heat up from 20°C to 24°C (15
minutes per 1°C).

Calculated / Status
11.
Calculated Top
Vent Temp.
Calculates the temperature for the opening of
the top vent corresponding with the settings
defined and taking into consideration the
influences.
0o to +100° C
12.
Calculated Side
Vent Temp.
Calculates the temperature for the opening of
the side vent corresponding with the settings
defined and taking into consideration the
influences.
0o to +100° C
13.
Vent Limitation
Vent function may be limited due to a higher
priority event.
Ex: If it is raining, then the vents will proceed to
the “RAIN” position, and the Vent Limitation will
display Rain.
