Device description
The digital climate controller
GROW
BASE
•
is the control station for the ambitious indoor gardener. A number of different devices
and sensors can be connected, which guarantees maximum flexibility.
•
is similarly able to control standard duct fans as well as EC fans, offering maximum
flexibility.
•
keeps the 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.
•
can be updated via the USB port.
•
brings a 24h timer for switching lights, an interval timer with separate settings for day
and night as well as multiple event timers.
•
has a battery powered real time clock to keep track of time even if the controller is not
connected to the mains supply.
•
can dim compatible lights using a 0-10V/1-10V signal. Ramps for sunrise and sunset can
be configured.
•
is equipped with four programmable power sockets.
•
has a transistor output (MOSFET) that can be used for switching external DC relays or
contactors.
•
is able to control the CO
₂
level in the grow room with a CO
₂
sensor
CARB
SENSE
connected.
•
is able to calibrate the connected CO
₂
sensor.
•
ensures a constant negative pressure in the grow room, avoiding the escape of odours
from the grow room. To maintain an accurate negative pressure, a pressure sensor
PRES
SENSE
can also be connected.
•
uses the current sensor values to calculate the values expected in the future. This enables
the controller to react precociously to changing sensor readings.
•
is able to regulate the temperature and humidity as precisely as ±0.5°C/±1% RH. *
•
uses well-tuned PID algorithms for controlling the environmental conditions.
•
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. (individual for day/night)
•
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, CO
₂
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.
