solar hot water control units

Pro controllers carry all the basic functions of the Delta–T, but include additional features such as more sensor inputs, relays, and most importantly, energy metering and performance monitoring. All versions of the Pro controller come preinstalled with software allowing the controller to record and monitor energy data for the life of the system. This data can be uploaded to our website, where a user can monitor and make system setting adjustments miles away from the actual installation.

There are primarily two versions of the Pro Series controller. The Pro and Pro Lite. The main difference between the two is the number of sensor inputs and relays. The Pro Lite comes with 2 sensor inputs and 2 relays which makes it suitable for Domestic Hot Water (DHW). The Pro comes with 5 sensors and 3 relays which makes it suitable for not only DHW but Pool, Space and even combination heating.
