Controller Operations: Stages – DIF, DAY, NIGHT
The ClimateBoss has three operating stages (DIF, DAY, and NITE).
The DIF stage allows you to adjust the temperature a few hours before sunrise to help control
crop height.
The DAY stage allows you to take advantage of solar energy to increase the daytime
temperature so you can maintain the correct average daily temperature to control crop
maturity.
The NITE stage allows you to lower the temperature at night to save on heating.
Controller Operations: Target Temperature
The figure below explains the workings of the stages, DIF, DAY, and NIGHT.
Figure 4 shows the controller programmed the DIF stage to start at 06:00 (6:00 am), the DAY
stage at 09:00 (9:00 am) and the NITE stage for 17:00 (5:00 pm). The target temperatures for the DIF
stage: 50
F, the DAY stage: 70
F, and the NITE stage for 65
F. As indicated by the arrow, at 8:00 am you
are in the DIF stage and the target temperature is 50
F.
