I have a solar thermal system on my house and that system is run by a differential temperature controller having two thermistors. The controller does not have any kind of readout on it, thus I have no way of telling what the two temperatures are at any given moment.
My question is: is there any way to wire a digital display into the controller to read those temperatures? The two sensors are 10,000 ohm two-wire thermistors. The sensor inputs on the controller are 0-5VDC and the thermistors are of the NTC type. Are there any LED displays made that run on a 120volt power source and accept a 0-5VDC input that can be scaled as needed? Any assistance is greatly appreciated. Thank you.
