GROW
BASE
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 CO₂level in the grow room with a CO₂sensor CARB
SENSE
connected.
•is able to calibrate the connected CO₂sensor.
•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, 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.
