I purchased this controller along with a PT100 RTD. I am getting about a half degree/min temperature drift. Could it be a bad RTD or the Controller?

Might be normal margin of error for the temp probe or it might be draft of air near temp probe tip .

I have no idea what the temperature is. It gets pretty hot and I think that's what happened to mine. I am guessing that it overheated and the motor burnt out??? No other reason for it to have stopped working after a few months and under 10 usages. Maybe someone else actually clocked the temp.

Since we have owned it the temps have varied from 100 to -19... Worked perectly still on my first set of batteries also.

I don't use a speed controller for my setup, but I can tell you that this broke down on me in less than 2 months. If there's a way to check without buying anything new, just tell me and I'll respond back.

My unit works fine. Does the red light on the sending unit flash on when you press the on button. If it does and the base unit is plugged into a working outlet (double check this by plugging the light directly into the outlet and turning the light on) then I would say you have a faulty controller.

That is a great question that I never thought about! I have used mine for over a year now, on pinball machines, and really like how it works. Do not know the true temp at the point, but will definitely have to check that out.

My guess is that you have the "low temp" value set higher than what it is sensing as the current temperature. I never use the low temp thing so I have it set at 35 degrees and I never have the issue you are describing.

I have the model with the additional display module. I does get a bit warm. I called PI and discussed this with a tech. He had me measure the OHM rating of the actuator which employs a copper coil and is basically an electromagnet that is in the solenoid the allows power to pass thru the unit. He indicated the some heat is OK.

I'm in WI (we had frigid temps this month!) and it has been running fine for us. We set ours at 72* and it stops running at about 72-73. Yours may be defective?

Wish I could help, but I returned my unit because it was DOA.I replaced it with a Duxtop 8100MC. I don't think the temp goes that low.

Eric:Like you, I was unable to get a direct read from either of my 2 remote sensors. It, supposedly, will use the readings to "average" the temps, but like you, I would love to see a direct read-out on the face of the stat!Sorry I couldn't help you . . .Mike

Mine is doing the same thing. It states the max temp is 190, so setting it at the max should be safe and it operate normally. Has anyone else set there's at the max and it works fine? thanks

I am not certain it will still work since I don't know what was the cause for the temp spike. I suggest that you test the function by changing your setpoint and see how it responds. Given the low cost of the unit, I'd not hesitate to replace it if my process is important. Good luck.

No. My control unit has 4 buttons below the display. But this might indicate that mine is an older model as it also lacks a low control temperature of 88 F, the lowest temperature I can set mine at is 113 F. We are pleased with our pad.

Mine is only about 6 months old, but I run mine at 91° and it has worked great so far. Maybe check that it is installed according to specifications? Or you may have a defective unit.

Not sure about this controller since it went up in smoke! Not sure the amp rating is accurate..

Is the fan the same fan you purchased with the original controller?? If so you shouldn't have to re-progam the control. When we got our replacement control we put in new batteries and it worked right away. If its a different fan then the original you should probably contact the manufactuer of the fan for help. I don't remember putting in any code???
