BATDTC Differential Temperature Controller Kit - $44
The BATDTC differential temperature controller is a reliable, easy to use differential temperature controller for solar hot water heating, solar air heating, attic cooling, root cellar cooling, you name it. The controller is powered by two AA batteries, so it doesn't need another power supply, and will run 3 years on a set of batteries! Being battery powered make it simple to install in remote applications, solar powered systems, etc. It has a relay output that can switch either DC or AC load devices like pumps and fans, up-to 2 amps.
Screw terminals are provided for connecting the temperature sensors and output to the controller.
Max Temp adjustable potentiometer for setting the maximum tank temperature or room temperature.
An LED indicator provides status and alarm information for the controller.
The BATDTC Controller Kit comes with two temperature sensors and the controller.
The User Manual is available for download below. MADE in the USA. For ordering Info click here.

myDTC Temperature Controller FamilyAll myDTC controllers can do any of the following temperature control applications:
1. Differential temperature control for solar water heating and solar air heating. 2. Heat / Cool thermostat control with wide temperature range 3. Outdoor Reset control / Auto-differential control for wood boilers 4. Geothermal Heat Pump flow control based on differential (with Analog Output) The myDTC-1R can do any one of the three control types above, fully programmable. The myDTC-2R can do two of the three control types above, fully programmable. (For example the -2R can do a differential control for one relay and a thermostat for the second relay output) The myDTC-4 can do four of the three control types above, fully programmable. (For example the -4 can do a differential control for solar hot water, and three different thermostat controls. Additionally the MOSFET DC outputs and Analog Output can provide speed control for pumps and fans based on temperature or differential temperature as well (myDTC-2F, myDTC-4 models). All myDTC controllers feature 32 bit ARM processors Extra features include: BTU meters for differential mode, new temperature control capabilities, pi loop control, and optional RH / Dewpoint control. We build all our controllers here in the US. Check out the manual below for detailed information. We will be adding some videos and pictures in the coming days along with a user blog. Keep and eye out for updates. Email: smith100griggs@gmail.com if you have any questions about the new controllers.
