I bought a better thermo coupler for this unit. Its a Type K. When I hooked it up it showed a HHH on the screen. Is the type K the wrong type

This uses a NTC thermistor (measuring resistance) and is not compatible with a thermocouple (measuring voltage).

The Previous answer is right. Thermocoupler is the wrong sensor for this controller. It needs a 10K ohm NTC (Negative Termperature Coefficient) thermistor. The 10K ohm is the resistance of the thermistor measured at 25 degree C.

I don't know but be sure to use the wiring specific to your device. The diagrams on line don't match all devices.

I had confusion with that also. My suggestion is to just ignor it and do not mess with it because using just the blue dial works great and the high low is not needed. Using the high low just complicates things until you have had some experience with the heater and you have already set the temprature with the blue dial. And once you have set the temprature with the blue dial you do not need to use the high low anyway.

I can't help. Sorry. I thought it was a piece of junk. Burned all my toor dal. I bought an expensive good one and love it.

I'm not sure what type of gun you have but you should have checked your connection before you purchased it.investigate if its cheaper to return it and buy the right hose or to purchase the right gun.. Remember that you will have to pay return shipping since it was your fault you did not verified before you orderd.

Hello Michael, I thought it necessary to let you know that after using the Mr. Htr Quick disconnect hose with only a one stage regulator on it has become a problem. My Mr. Htr Big Buddy went crazy. I do believe that if it were not for a Higher Power, I could have been in a bad way, or had a bad fire. Now, I'm still using a 100# propane tank on my Mr. Htr Big Buddy with the same hose, but I had to buy another regulator. And yes, the regulator is a two stage regulator and I got it from Lowes. I truly hope all is well with you and that the same Higher Power has covered you with protection and blessings. I would love to hear from you in reply to this note to know that all is well with you.

Good technical answer below, I have used the device for about 1 yr now and for a long time I used other devices in conjunction with it when monitoring temp measurements. I have found the accuracy with K type thermo couples never differs greater than +/- 2.0 °F. I just put it through a calibration event and they reported it to be within 1.0 °F. Our testing with this device is limited to industrial temp ranges (-40c to +85c)

I ordered the Fluke 116 from right here and it comes with the integrated K thermocouple. However, it comes with standard black/red test leads, and not the colorful ones shown in the picture.

I did when I bought it, but I found the unit didn't work. I bought a better model from Midland. Midland shipped HH50 replacement but I have no need of it now.

The one I have came with a thermocouple rod and it need to go in the radiator, the rod should slide through the fins of the radiator. If you have a the version with the threaded thermocouple then the thermocouple need to be in direct contract with the coolant. This would be best of used as the coolant temp sensor.

I think they have the description wrong, I googled 80 series blue and it is a different thermostat, also my new thermostat is b@w display!The thermostat that I replaced had different wiring though, it was the same but it did have an extra jumper wire, I had to study it for awhile to figure it out but it worked when I hooked it up, my old one was like 20 years old so I think they upgraded it!

Per the internet and some experience with thermocouples, it may mean bad thermocouple. If this is the case it is broken.

The AG13/-LR44-357-SR44-A76 are all cross referenced. I did not see one with a "H". Buy it, try it, see if it works they are not that expensive

Hi Mariane, the model you are referring to looks exactly like the one I own. The coupler I purchased fits perfectly and works great. FYI, you might want to purchase the small wrench/tool as well, it is simple to use and in my opinion, a must have.

I had the same problem on one of the three I bought. I just put some thick gas rated Teflon tape. Mine was just slightly to big. If it's just way to off send it back

They are designed to match the tonnage of the unit. The one I bought did not help at all as my Compressor was shorted.It was under warranty, but still cost me $1K to have the new compressor installed, hazardous waste and freon charges etc. You will want to do some searching on how to completely check your system and how this installs before you buy it. I did most of the tests recommended, but did not do all the leads on the compressor, so I bought something that did not help. My HVAC guy told me the kits really don't help a heatpump much? Live and learn.

Make sure the current rating. matches the mtor you are replacing..although it mau appear to be the same if it is too low it will overheat and thermo shutdown. I made this mistake

Replace it! I'd contact K&H; and make sure they are aware of the issue. They sell replacements, look for K&H; Pet Bed Warmer, size small.
