Day and night Setting
All sensors are equipped with a light sensor, which is used to determine whether the controller works
during the day or night. In this document, the daytime is defined as the time when the remote sensor
senses the light, and the nighttime is defined as the time when the light is not sensed in the room. The
actual time of the day does not affect the day or night mode controlled by Hydro-Pro.
When there are multiple probes, and the sensing status of different probes is inconsistent (for
example, one of the senses the day and the other two senses at night), it is decided by a simple majori-
ty. The sensor of day and night judges that the light intensity coefficient is determined by the device
and does not need to be set by the user.
The Hydro-Pro master controller is preset with default day and night control parameters (shown in the
Factory Defaults and Control Limits section of this document) so that it can be used immediately out
of the box. The Hydro-Pro controller will display the date symbol in the upper left corner of the
day/night mode.
Day mode control: The Hydro-Pro controller outputs signals to the corresponding device by monitoring
the relative humidity, temperature, and CO
2
concentration in the room based on the day control
parameters, thus maintaining them at the required level in the environment.
Night mode control: The Hydro-Pro controller outputs signals to the corresponding device by monitor-
ing the relative humidity, temperature, and CO
2
concentration in the room based on the night control
parameters, thus maintaining them at the required level in the environment.
In night mode, only the CO
2
concentration monitoring and alarming are available, and the correspond-
ing output device will not be activated to save CO
2
.
Light dimming adapter control
The Hydro-Pro controller is equipped with two channels of independent or interlocked light control
logic; meanwhile, the main supplementary light line and the auxiliary supplementary light line are
available. In the Hydro-Pro system, a maximum number of 20 light dimming adapter modules (LDA-1)
are equipped per channel.
The LED-type and HID-type light are available. Moreover, there is an automatic high ambient
over-temperature detection mechanism (high-temperature shutdown function), which can turn off the
light when the temperature is excessively high.
