Two versions have been available (now only the 4-season model). Both are powered by an external 12v waterproof power supply.
The advantage of a mains powered system is that you are not limited to maximum watering times like you would be with a solar (battery) powered system.
Do not place mains power connectors in damp environments. Ensure that any mains electric connections in your greenhouse or polytunnel are installed by a qualified electrician.
Mains, 4-season : full environmental control
- 240v power supply included.
- 3 additional output ports for either heaters, grow lights, or extra pumps.
Mains (Irrigation only / 3-season)
- 240v power supply included.
Maximum capacity
The control unit outputs will provide 12V at a maximum of 6A per output.
Firmware controls ensure that only two of the three outputs can be on at any one time.
Prior to December 2023, the internal fuse will blow if you attempt to draw more than 15A from the system. The box will need to be opened to replace the fuse - this will invalidate your warranty - please return to Harvst for a repair. Since December 2023, the internal fuse will reset after a few seconds, and the device will reboot. If the fault persists, the fuse will trip again.
