There are two different climate control systems for the Niwa Grow Hub:
● One is for temperature, which operates the A/C trigger (or fan if there is no A/C set) and the heater based on the current temperature readings and target. Then, for example, the A/C (or fan), will be turned on when the temp is above target and the heater will be turned on if the temperature is below target.
● The other system controls the relative humidity, and it actuates the humidifier, the dehumidifier (or fan if there is no dehumidifier set) based on the current humidity readings and the humidity target.
The climate control cycle will adapt to operate only the pieces of equipment assigned in the outlet configuration.
Dead zones
In order to protect your equipment (heater, fan, A/C, humidifier, or dehumidifier), the Grow Hub enables a “dead zone” for both temperature and humidity control.
- Temperature dead zone range: 0.3ºC
- Humidity dead zone range: 2%
For example: If you set a humidity target of 62%, and have a humidifier assigned to your Grow Hub, your humidifier will turn ON when the current humidity is lower than 60%; and it will turn OFF when humidity is greater than 62%. On the other hand, If you set a humidity target of 62%, and have a dehumidifier assigned to your Grow Hub, your dehumidifier will turn ON when the current humidity is higher than 64%; and it will turn OFF when the humidity is lower than 62%. This dead zone will prevent your humidifier and/or dehumidifier from turning ON and OFF constantly when the current humidity is close to your humidity target.
