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 mode two; it will switch relay output on only if the sink temperature is below target temperature. When sink temperature rises 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), fully assembled, programmed and tested with or without plastic case, with or without waterproof sensors. All sensors comes in stainless steel tube with 2 meters of cable. For more options, contact us.
Requires two DS18B20 1-wire sensors or two NTC10k thermistors or a combination, one DS18B20 and one NTC10k.
