Switch from thermostats and save money. Research shows that using a simple, centralized control reduces energy consumption. The MiniSTEP is an easy-to-use 4-stage control. It offers more energy savings than thermostats because it uses a single temperature sensor. This prevents heating and cooling equipment from operating at the same time.

The MiniSTEP’s an ideal control for a single greenhouse with standard equipment. It’s very easy for a non-technical person to operate and adjust. I often choose this control for school projects because it’s easy to train the teaching staff.  A simple control is perfect for these projects making the MiniSTEP a great fit.
