Pictured below is a modified version of our standard 2014 Solar Water Heating Pump Controller with LCD.

In addition to the standard digital temperature sensors for the solar water heating panel and the hot water tank, this version adds a third sensor to measure ambient air temperature, and a fourth to measure the temperature of the top of the hot water tank.

The LCD display has been modified to show the solar and hot water tank temperatures for five seconds, and then the ambient air temperature and top of tank temperatures for five seconds. The bottom line of the display still displays system status and settings information to the user.
