Introduction

The ThermokLogger-4A is designed to provide an affordable and easy-to-use differential temperature controller for solar heating systems. It is a four channel 10K thermistor display and data logger with programmable solid state relay outputs.

The ThermokLogger-4A records directly to a Secure Digital (SD™) card to provide convenient data downloads. To use the recorded data, simply insert the SD™; card into a card reader attached to a USB port on your computer (Windows, Macintosh and Linux). To view and graph the data, click on the spreadsheet corresponding to the day of interest. Practically any spreadsheet program can be used to view, graph, and analyze your data.

Applications

The ThermokLogger can be used in both Solar Hot Water and Solar Hot Air configurations. below are some diagrams illustrating these applications.
