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.

As of December 2016, Heliodyne is exclusively offering a new version of the Pro controller called 3rd generation with Beaglebone. These Pro versions come with default Modbus and Ethernet connection for remote monitoring. For WiFi remote monitoring, order the WiFi + Ethernet version or purchase a WiFi dongle separately to add to the board (3rd gen versions ONLY). For initial set up, a direct computer connection to a laptop with a USB port and a mini USB to USB cord (supplied with all 3rd gen controllers) will be needed along with a driver that can be downloaded from this website. The Pro comes with 5 x 10K ohm sensor inputs (T1 and T2 are mandatory for operation) and 3 relays which makes it suitable for not only DHW but Pool, Space and even combination heating.

*Please note that the current version of the Delta-T Pro controllers requires a mini USB to USB cord connection and laptop with USB port. Please download the Beaglebone driver on whichever laptop is being used to connect to the controller.
