Delta-T PRO Direct Ethernet Plug In

For use in open-loop, closed-loop or drain-back solar heating systems.

This Delta-T Pro solar hot water system controller has been specifically designed to control solar thermal collector systems, including open loop, closed loop with a heat exchanger, drain back, residential domestic water heating with electrical ignition gas single tank storage, combination systems with space heating, and commercial systems with variable speed pump operation.

There are two versions of the Delta-T Pro, one with a 10Base-T Ethernet connection (DLTA 000 001), and one with a Wi-Fi/802.11b Connection (DLTA 000 002). The controller comes loaded with interface software, accessed like a web page through any PDA, handheld, phone, laptop or computer with a rich HTML internet browser such as Microsoft‘s Internet Explorer. Connecting the control to an existing home or office network will enable any user on that network to view the system parameters and thermal performance data.

For the most basic system, the control requires two SAS-10 (10,000 Ohm) Thermistor Sensors , while additional inputs are required to take advantage of the more sophisticated operations, like energy calculation and data storage. Please see the table at the end of this manual for functions and their explanations, as well as the inputs required to run them.
