Rated 3 out of 5 by Easy to install, accurate control. Only some units I have had to replace after 1 year. Jury is still out on how durable they are. September 24, 2013
Rated 5 out of 5 by Easy to install and user friendly. Good Thermostat for just about any project where temperature control is an absolute for maintaining precise monitoring and control of devices. August 7, 2013
Rated 4 out of 5 by Installation was straight forward and programming was very easy.I did not see a warranty attached so that leaves me wondering... March 16, 2013
Rated 4 out of 5 by Cheap and Easy to use Ready to use out of the box and anyone can set it up (don't need controls specialist to do it). They are relatively cheap and Rencor offers many different options to fit your needs. I have found that I have had to replace three controllers out of five in the last two years. The units they are in are only five years old now. May 17, 2012
Rated 5 out of 5 by I'd be tempted to use one in my house Excellent stat. I have 12 of them in service right now, some for over seven years and haven't had to replace any.They are used in high humidly and sometimes direct water spray environments without a glitch. As much as I like Grainger, look around, you might find a better price. May 1, 2012
Rated 4 out of 5 by This product performs swimmingly. This product is easy to install and performs well to control temperature. April 4, 2012
Rated 5 out of 5 by Easy to program and they last a long time. We have been using these units for 5 years and only had to replace one because an operator hit it with a fork truck. March 22, 2012

Answer: 
This is what the supplier says about that. "The sensor is designed for air temerature and is not liquid tight". You may be able to use it with a immersion well, but you could lose accuracy.

Answer: 
I use one of these with the sensor in a 120°F water tank. The sensor has been underwater for about five years except for when the tank is drained for the winter. Still working like the first day it went into service.
I would say it is very waterproof.

Answer: 
I use these on jacketed stainless steel tanks inside a thermal well.
Sometimes when the crew washes the tanks the wells are filled with water, and have had no issues with them. Hope this answers your question.

I have one of these units controlling a chilling unit in a walk-in wine cellar. It has functioned flawlessly for several years. What I would really like to do is to vary the program for time of day. Basically, do my chilling at night and completely shut down during the day. What I don't want to do is toss out a perfectly working temperature control.
I had thought about hooking the chilling unit up to a time switched power supply so that the temperature control unit is simply ignored during the day. This isn't elegant but might get the job done. What would be elegant would be an addon to this unit that would permit some degree of time control. My unit runs once or twice a day in the summer and sometimes runs only once a week in the winter.... shifting the time of day it runs should not greatly impact the temperature swings which are tolerable at up to 10 degrees.

Answers

Answer: 
Grainger has contacted the product supplier and has been advised by them of the following.

You may be able to use a mechanical/digital 24 hour timer to control the voltage to the temperature control. This would only allow power to the unit during the times of day you want the unit running. I would recommend calling our electrical tech support team at 800-472-4643 to assist in selecting timer for the application.

Answers

Answer: 
Grainger has contacted the product supplier and has been advised by them of the following.

It is possible this control will work with electric baseboard heat. However, we need to know voltage, watts, and amps in order to confirm compatibility. This control is only rated for 16 amps @ 120 volts and 8 amps @ 240 volts. You may want to call HVAC tech support at 800-472-4643 with specs from the baseboard heater.
