I am not familiar with the Emerson controllers butI have found that most often the valve is the weak link. It is important that the wiring is correct, if any two leads are swapped the valve will run...

SOME manufacturers still believe in manufacturing in the USA and providing 24/7 phone support and training:whistle:

Outside the box. Most fit into a handybox outside near the door where they have to actively reset it once it times out.

There is also an input for SYSTEM OFF but I think you are on the right track with a simple wind-up or electronic timer. I suggest those all the time for that sort of application.

Although this is an after the fact need for a solution, some modern electronic controls have a door open mode. When the door opens the fans go off immediately. A minute or so later the LLS drops...

Yes. 0.85 is reasonable in most cases.

here is a link to a site that has an amps to watts and watts to amp calculator. I comes in handy.

Great. Please let me know if you have any questions

Ordinarily, defrost is terminated on temperature. In coolers with air defrost, the coil sensor may not hit termination temperature if there is no source of heat ( doors, panel leaks, warm product). ...

Someone mentioned the KE2therm controller, and obviosly, I agree😉
Seriously, if the coil is clean but the fan shrouds are iced I look at a few things. A defrost too hot or too long may blow off...

Yes, The KE2Temp+Defrost is a defrost clock and thermostat in one control. It has a battery backup to hold the defrost schedule in case of power failure.
Wiring is very simple, constant power is...

Unless they really use the time to steam clean the boxes, I am in favor of letting them run but at a higher temperature to prevent mold. Running should keep humidity down also. A controller with 2...

It depends on what "pulse" actually is. Our pulse happens on how fast the coil temperature rises in response to the heaters. The on/off cycles are minutes long rather than seconds and do not harm...

I like this idea:angel

There are lots of good comments here and it may be a combination of them.
Heaters can be "pulsed" to keep coil temp down during defrost. The terminator can be in the coil for more accurate defrost...

Glad it worked out but did the LLS stop buzzing? Usually a sign of dirt in the enclosing tube, low voltage or coil not seated properly.

Yup. From the simple KE2Temp and KE2 Low Temp to the smart Adaptive, Evaporator Efficiency and Rack Efficiency. Presumably all future products as well. See them all locally on a PC, wirelessly and...

It might be a way to connect ALL Ke2therm controllers to one excel style dashboard and then have it self connect to the internet with remote setting, monitoring and email alarms:whistle:

Thank you for your compliments and support.
Our business model is to provide the best products and customer service second to no-one!
I didn't personally take that call but I am passing your...

Hi Johan, Glad you are doing well!

These go to 11

[QUOTE=joejax;22483041]No way. On a walk in? That is way cool. I wonder if you can download how many times the door is opened and maybe wire up a VERY loud horn when the door is open too long. I...

Genesis is exactly right. Remotely you can change one of the digital inputs to "system off" and toggle to the mode of "open". This is much better than removing power. The controller is not harmed...

I am glad this thread resurfaced after 7 years, it really points out the changes that have taken place since 2008.
Modem, what's a modem? The internet has replaced dial up and that is great...

Long ago in my Sporlan days I seem to recall there was a system with a TEV in series with a cap tube. The TEV was just there to keep a constant pressure to the cap tube, but my memory is not what it...

I didn't see that it did or did not have electronic controls. if not, then checking the fan delays and terminations should be a large part of the problem. There should also be a drip time after...

yes to all the above. Without a slug of metal inside the coil to complete the magnetic field, all you have is a coil of wire connected across the line voltage. A better example is a toaster and the...

You accept a little oil foaming, why do you have a problem with this?;)

The Trenton electronic evaporator control has sensors mounted in the fins of the coil to terminate at 50* (default). This can be adjusted but at 50* coil there will be no steaming but will still...

The fan side of the coil is usually the coldest. If there was a short charge or choked TEV, I would expect the coil to frost more close to the TEV.
I assume you checked the heaters, since it going...

Once tried a heat gun to dry my hair quickly
Should grow back eventually...

Break down water? Now you have free hydrogen and free oxygen in the system. Don't think so!

I have found that the torch flame sort of bounces off the ice rather than heating it.

The real issue is to solve the icing problem. Placing a solid state sensor, or two, in the fins of the coil...

Pardon me if this shows up twice, I lost the internet for a moment.

For freezer applications, we suggest KE2 Evaporator Efficiency controllers on each coil,since the needs for defrost will be...

The controller will control a liquid line solenoid and/or an EEV. When satisfied on temperature, or during defrost, the EEV will close along with the solenoid. On a retrofit, there is no need to...

Be careful with temperature sensors, they are not all the same. There are nominal 2k, 5k, 10k, etc but that only means they have a resistance of 2,000 ohms (or 5,000, or 10,000 ohms, etc) at 77*F or...

Sorry, i should not have included the website in the post.

There are three products and selection depends on your needs.
KE2Temp+defrost is for off cycle defrost, time initiate, time terminate. It is dual voltage and includes the thermostat and timeclock...

While it can't fix a leaky walk-in, a controller with pro-active defrosts and door switch controlled fans can help minimize the pain. We have had lots of good results with that. Heaters cycled on...

In a perfect world defrost clocks wouldn't be needed on a cooler, but the rest of us live in a world of open doors, people who want the coldest beer in town and clerks who turn off the fans because...

I hear bad things about Beacon, but then I am biased. There are other alternatives to the Beacon out there that may have more features and less cost. Ability to use any valve, free communication...

Do you have to take a stiff exam to work there?

I suspect it is both-short charge and damaged valve. The stem packing on TEVs is there to keep you from getting freezer burn when you adjust the valve, it is not a good seal. Without the seal cap,...

I am not sure if you are referring to the KE2Therm Temp+Defrost controller. The KE2Te3mp+defrost has a switch only for selecting 120v or 230 v. The "power robbing" mode is just a jumper to the...

I don't see the problem.If the product is right up against the coil it gets cold by conduction.:grin2:

There is no question that sensors have been a real thorn in the side of electronic controls. however, we have made great progress. Our parts per million failure i for temp sensors is 366 and for...

Mechanical timers and thermostats were good in their day but the world has moved on. Some of the original electronic controls were real nightmares-not particularly reliable and totally not user...

There has never been an owner who thought the box was cold enough or who didn't think that setting the thermostat very low makes the box get cold faster.
Some electronic controls can act as...

EC Motors (electronically commutated motors) come in a couple of different flavors. They can be constant speed, sometimes 2 speed and variable speed. Constant speed can be just two wires and all...

You are supposed to take the shipping plugs OUT!!! I thought that is what the FILTER DRIER is for!!!
