MAXDTC 8 / 4 / 2 Programmable Temperature Controllers
The MAXDTC line of temperature controllers provide programmable temperature control (Differential, HEAT/COOL), humidity control, and timer control on 2, 4 or 8 outputs. With 8 temperature inputs and 4 external sensor inputs, the MAXDTC provides excellent monitoring and control capabilities for even the most complex multiple control loop problems. When you add in its built in logging capability and 4080 records of logging storage with time-stamping, its also a top notch research tool for recording and measuring system performance.
The MAXDTC controller provides 10 different control modes that can be configured to create 16 unique control rules. Any input can be assigned to any control rule in any combination. Any of the 16 control rules may be assigned to any output or multiple outputs. This gives extreme flexibility and allows you to use less sensors to control more things. The MAXDTC supports the new MAX_TEMP, MAX-RH, MAX-SOL, and MAX_USER external sensors on inputs S1-S4 in addition to supporting upto 8 myTS Temp Sensors on T1-T8 temperature inputs.
The MAXDTC is configurable from a serial port interface. The MAXDTC has a 2x16 Backlit LCD display that can be used to monitor all the temperature and sensor inputs, all the output relay states, and all temp sensors and external sensors MAX and MIN values with the push of a button. This allows the user to monitor the inputs and outputs of the controller without needing to connect to the PC.

SimpleDTC Family of Temperature Controllers -- $52
The SimpleDTC Differential Temperature Controllers are the lowest cost option for controlling your solar hot water or solar air heating system.
Package #1 - SimpleDTC Controller and two myTS temperature sensors for $52.
Package #2 - adds a plastic enclosure and mounting screws for $59.
The SimpleDTC Differential Controller has two DeltaT selections, either deltaTon = 4F, deltaToff = 1F, or deltaTon = 8F, deltaToff = 2F. They also provide two selectable High Temp shutdown temps of 125F and 80F for solar water heating or solar air heating. The High Temp shutdown can also be disabled. Operating settings are selected by shorting the mode pads on the SimpleDTC with a screw driver tip. The mode value is stored in memory to ensure proper operation after a power outage. The LED indicator provides RELAY status and displays selected mode with blinks during setting. It even blinks S.O.S when a temp sensor is disconnected. No programming or computing interfacing is required to operate, just attach the temperature sensors and your 12V power supply to the screw terminal inputs and your pump or fan to the relay output and your running!
