INTRODUCTION INSTALLATION
The Dimlux maxi controller is a modular control system for operating and monitoring the Dimlux lighting, CO2 and
VPD. The EVO controller is available with and without USB log function. The controller also has a thermostat/hygrostat
function (AUX) and can also control a fan.
A maximum of 160 Dimlux light xtures or pre-selector devices can be controlled by means of two out-ports. The
controller switches the lighting on or off by means of a built-in timer. If a set temperature is exceeded, the lighting dims
automatically or – if necessary – switches off half or all light xtures off. A switchboard with timer/relay/reducers is
not necessary.
Besides lighting, the controller can also regulate the CO2 level in an air-conditioned room. A very accurate dual-beam
CO2 sensor can be used to control CO2 generators, cold CO2 installations and ventilation systems for air replacement.
On the AUX port of the EVO 1.2, an “auxbox” can be used to connect a humidier or a dehumidier, a heating system
and even a ventilator. Various parameters can be read and regulated in a VPD environment. The screen shows the
ambient temperature, relative humidity, plant temperature and VPD. The DATALOG function can be used to store all
values on a USB stick. The controller writes all measured values onto the stick every minute and these can be read off
later in graphic form on a PC.
The controller can also operate the lighting in two rooms in turns. This requires a second temperature sensor, which
can be connected to port RH/T2. The relative humidity sensor will no longer be required. The controller is modular: All
sensors can be purchased independently according to need.
Components
The controller
The controller regulates and operates the lighting, CO2, VPD status and any other
connected components (AUX).
Temperature sensor
The temperature sensor measures the room temperature and should be protected
against light (shaded). A cardboard cover is sufcient.
RH% sensor
The RH% sensor measures the relative humidity in the room. This is necessary to
determine the VPD or to control a humidier or a dehumidier. The RH% sensor should
also hang in the shade.
CO2 sensor
You can read and control the current CO2 level in a room using a very accurate dual-
beam CO2 sensor. The sensor can control a CO2 generator or a cold CO2 installation.
PT camera
The temperature of a crop can be measured using the plant temperature camera.
This temperature provides an indication of the vaporization of the crop.
The camera is also needed to determine the VPD.
The Auxbox
Auxbox Auxbox fan
An auxbox can be connected to controller’s aux port. The auxbox converts the maxi controller into a fully automatic
air conditioning system. The auxbox is available in two designs. The auxbox has two connections, one for a heating
system/heater and two for a humidier or dehumidier. The other design can also control a fan as well as a heating
system and a humidier and a dehumidier. The fan control is electronic and has no annoying buzz.
