Automated Greenhouse Heating Controls & Sensors
HH2 Integrated Controller
Our market leading heating controllers (HH2 & HH4) can work with both an electric system and a hot water system. The HH2 works with an aspirated screen, which hangs in the greenhouse and takes regular average temperature readings to enable the heat system to work optimally and efficiently.
The system is easy to use and intuitive. Settings can be set for night/day and overridden as needed. The HH2 also has the functionality to manage control between both the heating and ventilation system, making it the go to integrated environmental control solution. Multiple controllers would be used in a multi-zonal solution (1x controller per zone).
HH4 Greenhouse Thermostat
The HH4 controller is a simpler option that also works with a remote temperature sensor, and whilst not quite as intuitive as the HH2 still enables both automatic and manual settings. The HH4 cannot be used for both heat and ventilation. Clients commonly utilise the HH4 for ventilation control, but it can also be utilised for heat control. In a simpler, smaller electric heat solution sometimes all that is needed is a thermostat for setting the temperatures need.
All our control solutions and associated products are IP rated.
