Q&A
Some questions about intelligent iControl system you may want to know.

1. Can the iControl controller work with older Mars Hydro iHub or controller models??
No, the iControl Smart Controller is only compatible with the new generation iHub devices such as iHub Pro and iHub-4AC. The old iHub and older controller model (Controller43) cannot be used with the iControl controller due to hardware and protocol differences. Additionally, the new iHub-4AC also cannot be connected to the old controller.

2. What types of devices can be connected to the iControl controller, and how many??
The iControl controller can connect multiple devices including LED grow lights, clip fans, inline fan, humidifer, iHub Pro units, and iHub-4AC power strips. The actual number may vary depending on the total power capacity and how many RJ12 ports are available on the iControl. It’s best to refer to Mars Hydro’s user manual for specific port limits and safe load guidelines.

3. What is the difference between iHub Pro and iHub-4AC?
iHub Pro is a smart power strip that works independently, with built-in smart control capabilities. It can be used without the iControl controller and supports smart environmental strategies. In contrast, iHub-4AC requires the iControl controller to enable its smart features and cannot function independently.

4. Can iHub Pro or iHub-4AC control devices from other brands?
Mars Hydro’s smart control system is designed exclusively for Mars Hydro products. While other brand devices can be powered through the iHub Pro or iHub-4AC outlets, only basic timer functions (e.g., On/Off scheduling and environmental triggers) can be used. Advanced features like light dimming and fan speed control are not supported for third-party devices.

5. Are new and old Mars Hydro sensors compatible across controllers??
Yes, both old and new sensors are compatible with either the old controller (Controller43) or the new iControl controller.
This ensures flexible upgrades and sensor reuse across generations.

6. What are the differences between the new iHub-4AC and the old version?
The new iHub-4AC is exclusively compatible with the iControl smart controller, while the older version is only compatible with the previous Controller43.
Functionally, the new iHub-4AC offers an additional feature: environmental control strategies, allowing users to set devices to respond to temperature and humidity thresholds.
This makes the new version more advanced and integrated with Mars Hydro’s smart ecosystem..

7.How does the new iControl controller differ from the old Controller43?
The older Controller43 was limited to smart control of LED grow lights only.
In contrast, the new iControl controller supports a wide range of Mars Hydro smart products, including inline fans, clip fans, humidity control devices, and more products planned for future integration.
It also introduces comprehensive environmental strategies, making it a more powerful and flexible controller for modern grow setups.

1. What happens during a power outage? Will devices resume operation?
All Mars Hydro smart devices are equipped with a power-off memory function.
This allows them to automatically resume their previous operational state immediately when power is restored.
There is minimal or no delay upon restart.

2. How are devices triggered under temperature & humidity strategy mode?
In Environmental Strategy mode, if either temperature or humidity deviates from the set thresholds, the connected devices will activate.
This ensures that environmental conditions are continuously optimized for plant growth.

3.How do RJ12 compatibility and product limitations affect device control?
Only Mars Hydro devices equipped with RJ12 cables can access full smart control features through the iControl and iHub units.
If a product lacks an RJ12 port, it can still be used on the iHub Pro for basic features such as On/Off, Timer, and Environmental Triggers, but cannot access advanced functions like dimming or speed adjustment.

4. What is the standby speed of Mars Hydro inline fans and clip fans?

The standby airflow speeds of Mars Hydro ventilation products are as follows:

4-inch inline fan: 205 CFM

6-inch inline fan: 402 CFM

Clip fan: 300 – 315 CFM
These values indicate the airflow performance when the fans are operating under standard conditions.

1. Can I use multiple phones with the iControl controller and will settings stay synced?
Yes, you can use multiple phones to access the same iControl controller, provided they log in with the same Mars Hydro account and are connected via Wi-Fi.
Settings and historical data will remain synchronized.
However, when connected over Bluetooth, history might not fully sync due to limitations in local data storage when offline.

2. Can I control multiple grow tents with one iHub Pro?
No, one iHub Pro and one controller can only manage one grow environment at a time.
Multiple grow tents with distinct settings would require separate iHub/controller combinations for individual scene control.

3.Do specific outlets on the iHub Pro require matching Mars Hydro devices to function properly?
Yes, on the iHub Pro, certain ports such as Light1, Light2, Fan, and Inline Fan are not customizable and must be connected to their corresponding Mars Hydro devices.
These ports also require an RJ12 connection to enable smart functions like dimming and speed control.
The remaining outlets on the iHub Pro are customizable and can be used for various devices, allowing users to assign control strategies such as On/Off, Timer, or Environmental triggers according to their needs

4. Can devices without an RJ12 cable be used with the iControl controller?

No, the iControl smart controller requires an RJ12 cable connection to communicate with Mars Hydro products.
Devices that do not include an RJ12 interface cannot be recognized or controlled by the iControl controller.
To fully utilize the controller’s smart functions, ensure that all connected devices are RJ12-compatible.

4. Are all RJ12 cables from Mars Hydro devices interchangeable?

Yes, all RJ12 cables provided with Mars Hydro smart devices are universal and interchangeable.
You can mix and match these RJ12 cables between devices such as grow lights, fans, iHub Pro, and controllers without any compatibility issues.
This standardization simplifies setup and cable management in your grow environment.
