DDT2 is a digital differential thermostat for solar water heating and other applications with one relay output and two sensors.
The controller measures two temperatures. In mode one; if first temperature rises above the second temperature the controller will switch relay output on and will switch it off when the sink temperature rises above the set target temperature or the sink temperature approaches source temperature. In modes two/three; it will switch relay output on only if the sink temperature is below/above target temperature. When sink temperature rises/drops above the set point the controller will switch relay output off.
Note! Power supply operates on 230 V mains.
Available as partly assembled PCB (no terminal screw terminals, solder your own, pitch 5.08 mm), fully assembled, programmed and tested, with or without plastic case, with or without waterproof sensors.
