thanks for your videos the truth not everyone likes to share their knowledge thanks again greetings from houston tx

[@hvactechpr7872]

Awesomeness Maximus!! I'd used to do it all the time... Did that to about 2 traulsen but used a small mechanic freezer stat and the white paragon... Also used the supco EDT timer and I've done it on a hoshizaki freezer also about 3 times... Wow I miss Refrigeration work... Doing ac and Vrf now

[@Twisted2Logic]

I have been wanting to do that to a couple of of the exact same units that I work on. Electrical is my struggle and I am slowly overcoming it, a lot more in the last month or two then ever before so I don’t quite understand the wiring just yet but the video was absolutely great.

[@kingofthecrease30]

very nice job installing the components. It should work alot better now 👍

[@2020romania]

Another great video Dave, thanks for sharing. Often times simplicity is best.

[@persimonsen8792]

We are doing the opposite, converting to digital. Using external relays for load. Gives you more control of fanstart, drip duration, compressor minimum runtime & hold time. Like, if your compressor is a LST type, with PTC starting device, you wan't it to stop mnimum for ex. 5min before restart. I prefer Danfoss EKC202D and Dixell XR60CX. Most Dixell, which have some nice features..

[@leoashrae4199]

Back in the day, TI made a controller called the 5TI. I saw these in machines from Liebert and New York Blower. They used the 5TI because it used separate I/O modules, which could carry a load without overheating the logic module. I never had to replace an output module on one of these. But, those all-in-one controllers (like the tiny Omron units) were my bread and butter. They just can't handle constant high loads. Ever touch one that's been running for a while? They get HOT. Everything about them just seems to be too small to handle anything over 10 amps for very long.

[@alphatechrefrigeration3983]

Nice job Dave. Good call on the relay... that's what I usually do instead of a contactor in confined spaces.

[@aircooledtx]

Nice wiring old school defrost timer/relay and tstat. Good job,keep it simple.Dave

Michael Lee I think the customer was happy.

[@FireandFrostHVAC]

Great video Dave. The freezer will likely be super reliable now. Thanks!

[@AgentFunk]

Ive taken plenty of control boards out of mcquay heatpumps that were used for server room cooling and just put in relays to operate. Sometimes control boards can be to much of a hassle!

[@NorCal-refrigeration]

[@harrydickson4575]

Excellent job Dave 👍👍👍

[@JuanTodoli]

Plenty of that digital controllers here in Spain on every EVERY single reach in, prep-table, rail, etc IF NOT with resistor defrost. Very rare to see mechanical (some Theben Fri77 or Grässlin on old school walk ins). Ako, Eliwell, Dixell, Carel and Osaka are the norm. Zanotti on walk-ins. That said, these amperages this controler said can handle without external relays or contactors sounds simply incredible.

[@persimonsen8792]

What about Danfoss ? The most simple digital controller. Atleast the old ones, like EKC.

[@gene-khvacr]

Dave you dah man thumbs up galore to yah 😎

[@throttlebottle5906]

I prefer mounting the thermostat and time clock outside of that internal "wiring cover", so it's easier to access. mainly because we quite often have random power outages due to thunderstorms and some times snow, ice and high winds, so the clocks are always need reset to keep health department happy

[@NorCal-refrigeration]

throttle bottle what is ice, snow. You talk about. Lol.

[@louisdesouza2726]

Thanks Dave , great video , one thing I’d like to know from you is where you placed the temperature sensor ?

[@NorCal-refrigeration]

In the return air. So behind the evap. With air stream can flow over it.

[@SeanMackBuffaloStyle]

Nice clean job. Do you do all your nor Cal work after hours?

[@rocknight6815]

Could that relay be causing my freezer to heat up? once it reaches 10 below and cuts off it starts heating up. Within 2 minutes it goes from 10 below to 2° and kicks back on.

[@DanO181919]

On the old digital temp control on the True box, what sensor does the controller look at. Is it a return air sensor or a coil sensor? Thanks

[@NorCal-refrigeration]

Both. Coil sensor for defrost cabinet for set point

[@HVACRDUDE]

Where do the white and black wires go from the tstat...the wire nuts that are black and white!!??

[@arthouston7361]

Digital controls are a technician full employment program. However, the failure rate of components, like it or not, becomes a reflection on the person that the client sees, and that is you and me.

[@hvactechpr7872]

Got curious, where did you mount the bulb for the stat??

[@goldfinch1384]

Can you show us a wiring diagram on what you did please

[@heavydiesel]

Neat job Dave!

[@chenchris7576]

It’s potential relays you put on it? Thanks

[@octavianomora5712]

Great video, refrigeration Dave

[@throttlebottle5906]

when you said all mechanical in last video thought you meant an old school mechanical "cap tube-sense bulb thermostat" also :) least they used an actual "omron" brand relay and not come chinesium may work a week model

[@phil955i]

If the relay on the LAE controller can't handle the current draw when the condenser chokes up why not run a separate relay with a higher rating (as you did when you fitted the True relay)? Also, there is the option on most electronic controllers to disable the evap. probe & they then just revert to timed depending on what's set in the defrost duration setting. I get that you guys over there prefer electro-mechanical controls to electronic BTW, a colleague has recently emigrated to the States from here in England & said as much.

[@nickanto]

Worried about moisture at all not having a fan delay coming out of defrost?

[@jeremyvoshage2410]

I see the X terminal wire connected. Did you add a klixon up on that evap coil?

[@NorCal-refrigeration]

Jeremy Voshage different clock with different nomenclature. The 8141-00 x is not defrost termination.

[@jeremyvoshage2410]

@@NorCal-refrigeration Ah yes I am thinking of the 8145.

[@geckohvac3935]

Dave man i had a similar situation on a 2 door frontal freezer and then electronic controller was stuck on compressor mode never defrosting amd a big chunck of ice etc.. My boss told me to GTFO but i told the customer that i could probably retrofit all to mechanical controls . my boss told me to tell the client that its cheaper ro buy a new freezer 🤣😂

[@HVACRDUDE]

Bad-FUCKIN-Aass

[@Alex-yk6he]

First :)

[@OcRefrig]

id recommend adding a " Delay on break timer " to safe guard the compressor & give the relay a fighting chance. i would ad it to the relay coil side. just remember to clip the redwire on delay on make timer for 120 volt. i dont think the Etc has time delay feature. id set delay on make for 5 minutes. in case someone opens the door after compressor cycles off. Good news u stiill got room in that box. 😂😂😂

[@OcRefrig]

You want to use a " delay on break timer ". a " Delay on break " timer starts counting the delay down as soon as the timer is de-energised. a "Delay on make" timer - starts counting as soon as the timer is energised.

[@throttlebottle5906]

the ranco temp controller has an adjustable delay built in, to keep from short cycling, not sure how sensitive it is to power blinks, but I'd assume pretty fast and stay off for the delay. not many of them around here, majority is all mechanical/sense bulb setups.

[@OcRefrig]

sorry throttle , maybe i am wrong. its been a while since i used a etc. i just use the a421 and 1419. i could have sworn they had no asd. but i just read pdf and it says compressor delay. maybe its a new thing on newer models. i thought the older etc did not have dealys.

[@hvactechpr7872]

OcRefrigeration,Hvac & Electrical. Time delay is a must here darn brownouts

[@OcRefrig]

time delay will not help u with a brown out, you need a line voltage monitor like the video i put up a few videos back.

[@OcRefrig]

Good vid. How did u run the Etc sensor ? i guess there is a tube running up to the evap for the thermistors , i guess u just used that tube ? if u want to do a part 3 u could show where the sensor is , how u ran it , and do a wiring diagram of wiring on a piece of paper with exact wiring. id watch that vid. icant belive you fit all that stuff into that box. even true puts the clock outside. ive Replaced many of those Relays with contactors. thats the only thing i would have done different. i bsolutely hate those piece of shit true self contained relays. they are too light of duty in my opinion for a 3/4 hp, i know they say they are rated for it. But, ive replaced them all with contactors. i mount them on the Far left wall underneath , on the T-49F Freezers. it works awesome. Stiil, Cool video ! i Never imagined u could fit a defrost clock , a Etc 111000 & a relay in that Small box. Major thumbs up on that !

[@NorCal-refrigeration]

OcRefrigeration,Hvac & Electrical. The true relay works because it’s sealed so a little more safety if fingers get in there messing with the tstat. I drilled a whole in the box for the probe and ran the etc probe up the middle to the top strapped to the door divider. That’s the return air in the front.

[@OcRefrig]

Thanks. yea, understood. i figured u might of just attached the etc probe to the screw at the front of fan guard with a wire tie. thats prob how i would have done it. and use the chase for the thermistor wires where they run them up to evap area. but, drilling hole i s a Good option too and running up door jam works good too. allways more than one way to skin a cat.

[@fredisamaya1985]

Simple retrofit for that costly true controller...so have u try the carel or dixel controllers.

Well don't say our little secret about the cost of parts...please
