2 Specified normal operation
This digital environmental controller is designed for speed controlling of fans and switching a
number of other devices. Depending on the mode of operation, the controller’s power sockets
may be used for connecting devices below:
• Power sockets labeled “Multifunctional Out 1-3”:
o Regular duct fans with running capacitor*
o Humidifier/dehumidifier
o Lights
o Water pumps
o Circulation fans
o CO₂ valves/generators (230V)
o Heating mats
• Power sockets labeled “Multifunctional Out 4“:
o Humidifier/dehumidifier
o Lights
o Water pumps
o Circulation fans
o CO₂ valves/generators (230V)
o Heating mats
o Electric heaters
• RJ45 jacks labeled “In/Out”:
o CO₂ sensor
o Negative pressure sensor
o Temperature sensor for heating matt
o Output extender
• RJ45 jacks labeled “EC Fans”:
o Voltage controlled EC fans
The device is not suitable for controlling any other equipment.
Always ensure that the maximum output power of the individual outputs is not exceeded.
Please find further information on the device’s label or section
11 (page 24, Table 4) of this
manual.
Warning!
If the “intake” mode is selected for the “Multifunctional Out 1” output, only standard fans
may be connected. Other devices may be damaged in the “intake” mode. When shipped,
the functions of “Multifunctional Out 1 and 2” are set to “intake” and “exhaust”.
To meet the European EMC directive, the technique used to control the regular duct fans may be
used up to a maximum 600W. Do not connect devices with a power above 600W in “intake” or
“exhaust” mode.
Avoid exposing the temperature and humidity sensor to humility above 95% RH as the
sensor may become damaged.
*When driving S&P® fans of the “TD-Silent” series, problems may occur. Do not connect fans
with an integrated rpm control.

3 Device description
The digital climate controller GROW
BASE EC
PRO
• is the control center for the ambitious indoor gardener. A number of different devices
and sensors can be connected, which guarantees maximum flexibility. In addition, the
number of power outputs can be extended with an extra device.
• is similarly able to control standard duct fans as well as EC fans, offering maximum
flexibility.
• keeps grow room temperature at the desired value by varying the air flow of the fans.
• keeps the humidity in the grow room at the designed value by switching a humidifier or
dehumidifier.
• can additionally reduce the humidity in the grow room by increasing the air flow.
• is able to control the CO₂ level in the grow room with a CO₂ sensor connected or
without a CO₂ sensor.
• is designed for the connection of the following devices: EC fans (intake, exhaust),
standard duct fans (intake, exhaust), lights, humidifiers, dehumidifiers, water pumps,
circulation fans, heating mats, electric heaters as well as CO₂ valves or generators, CO₂
sensors, negative pressure sensors, additional temperature sensors for a water tank or a
heating mat and an output extension.
The last measured temperature and humidity values are used to calculate the expected
values in the future. This enables the controller to quickly react to changes and achieve
the desired value.
• is able to regulate the temperature and humidity as precisely as ±0.5°C/±1% RH.*
• ensures a constant negative pressure in the grow room, avoiding the escape of odors
from the grow room. To maintain an accurate negative pressure, a pressure sensor can
also be connected.
• supports the option to adjust the length of a day cycle, providing equal yield with less
time required.
• can control the temperature of a heating mat. The temperature can be set to a certain
value or a temperature relative to the room temperature.
• is equipped with an easy-to-use multilingual (English, German) menu. Many different
setups can be achieved, e.g. adjusting the minimum and maximum fan speed
separately for day and night. It offers a range of information including the current
temperature, CO₂ concentration, current humidity, min/max temperature values and
humidity, current fan speeds and other information regarding the operating condition.
• saves the settings permanently to ensure that they remain available after a power
breakdown or after the controller has been temporarily out of use.
*Provided that the sizing of the connected utilities is appropriate and the fresh air temperature is
sufficiently low. The tolerance is related to the repeat accuracy rather than the absolute accuracy.
The absolute accuracy is ±3%.

4 Initial use
Warning!
If the “intake” or “exhaust” mode is selected for an “Multifunctional Out 1-3“output, only
standard duct fans may be connected. Other devices may be damaged in the “intake” or
“exhaust” modes. When shipped, the functions of “Multifunctional Out 1 and 2” are set to
“intake” and “exhaust”.
1. Place the humidity and temperature sensor (7) in an appropriate position inside the grow
room, usually at the top ends of your plants. Please use the hanger (8) on the sensor cable.
The sensor should not be directly exposed to the fog stream of the humidifier. Connect the
humidity and temperature sensor to any of the RJ45 jacks labeled “In/Out 1” to “In/Out 4”
(13).
2. Connect the mains plugs (5), (6) to the power supply (regular power socket). The device
has two mains plugs, offering the option to share the load (current) to two different
circuits.
3. Set the function of the “Multifunctional Out 1-4” outputs and set up all other functions
according to your requirements.
4. If using regular duct fans, we recommend disconnecting the mains plug (6) first.
Subsequently, connect the fans to the corresponding power outlets on the controller and
then reconnect the mains plug.
5. Connect appropriate devices to the other power outputs.
6. Connect the EC fans to the RJ45 jacks labeled “intake” and “exhaust” (12), (11) using a
suitable cable.
7. Connect other accessories (sensors, output extender) to the RJ45 jacks labeled In/Out 1-4
(13).
Always ensure that the maximum output power of the individual outputs is not exceeded.
Please find further information on the device’s label or section
11 (page 24, Table 4) of this
manual.
Avoid exposing the temperature and humidity sensor to humility above 95% RH as the
sensor may become damaged.
EC fans have their own power supply cable, which should be plugged to a regular power
socket (always on). It should not be connected to a power socket on the climate controller.
The fan’s rpm control and turn off is made via the signal cable from the RJ45 jack on the
controller to the EC fan.
