The SureSwitch works great. I replaced my contactor with the SureSwitch. I didn't have an ant problem but there are plenty of ants near the outside unit. The SureSwitch has a quieter operation than a traditional contactor. The buzz that sometimes happens from the electric coil is eliminated. Good for bedrooms nearby. I use mine on a heat pump. I disabled the delay function as it will interfere with the defrost cycling in heat mode. I left brown out protection on. SureSwitch includes contacts for a crankcase heater which is excellent. Worth the investment for longevity IMHO. Thanks for the video @HVAC School
You did not mention the feature that it times the snap on at the middle of the a/c wave when there is zero potental across the point thus elemination arcs, metal transfer, and future restance.
Would love to see you do a video on how a Daiken Quaternity ductless unit splits the coil and heats and cools simultaneously for dehumidification. Love your videos, Thanks
If it keeps the Copeland scrolls from running in reverse when the power blinks, totally worth it. Never had so many calls with customers with recent installs with the compressor being "noisy" this year.
@@johnconnor7501 If there is a brief power outage (like a fraction of a second) the high pressure can make the scroll move backwards for that one bit. When power is re-energized the motor runs in reverse. This is on single phase compressors.
@@johnconnor7501 Thankfully it is rare but it does occasionally happen. This scroll design is actually a very good one. it's just been aggravating this summer with the high power demands and the electrical grids being a little crabby.
I wonder if they make a 3-phase contactor like this? That would be nice for larger commercial applications. I'm constantly replacing pitted contactors in some of my Data Center CRAH's.
What about the heater that goes around a compressor? You know when the compressors off not running to keep the compressor warm so the refrigerant doesn’t migrate in that area to flood out the compressor if that becomes a coldest point.
Add a normally closed contact with a 110 coil . Use the leg this still switches to the contractor coil . Simple mechanical thermostat in line , the unstitched load to the other leg of the heater if it is a 220 band or only the one switched line if 120.
@@coolhandrob8893 Totally wrong. The contactor does start in the middle of the AC sine wave where voltage is near zero to minimize contact arcing, but once latched an added soft start would ramp up voltage and current in slower manner getting the system up to full speed thus reducing the locked rotor amps that would occur in a traditional system. Using only the sure switch, once the latching occurs, it would still pull the standard number of amps close to the rated locked rotor amps to get the compressor going.
@@TheModelmaker123 So from your first sentence I'm not "totally wrong" You agreed with what I said and then simply described how a soft start works. Essentially adding nothing to the discussion. It wouldn't hurt to add a soft start but you may want to look up the word "redundant".
Pumpdowns are on the way out anyways in residential for a couple reasons. For one, you really shouldn't be pumping down with scroll compressors anyways. Two, you CAN'T pump down with microchannel coils. The first of which are pretty much ubiquitous, and the latter of which is becoming unfortunately more common by the day.
If it last twice as long then it pays for itself. 5x the contact area and not exposed to the weather? I won't be using them on my personal equipment, but if they can prove it last longer definitely worth it in humid areas. Heck down near the sea contactors go out like crazy.
Great product. Proved reliable in multiple installations, and completely silent.
I like that it's a "no ant" sealed contactor. great job!
This makes it easier than all the cycle timers and under voltage sensors I use to add to units I had at the hospitals I worked at.
Our company been using them for the past two years. They're great. No issues so far.

Good mention. No more pitted contacts

Interesting and most useful as well as practical a must carry and i like the multi voltage coil a sure winner.

Hello, what you mean running in reverse when the power blinks?

@@swainer8014 wow! Didn’t know that. That seems like a huge design flaw to me.

Great video Bryan, love the content!!
I’ve seen a few of these. I always wondered how u can manually run the system with this

Great video, Appreciate all you do.
They also make a product called core sense, for copland scroll compressors. I put one on my trane heat pump.
I like that contact or I'm going to purchase one for my AC system it's a very good investment I believe thanks for the video..👍
Yes I know this on hvac know it all channel they are great
Off the top of your head, do they make a 3-phase version of this contractor?
Pretty sure its single phase only.
Top notch 👍🏻

@@Garyganeu No need, the SureSwitch has separate terminals for a crankcase heater.
Yes, the SureSwitch has terminals to support a crankcase heater. I use the belly band heater on mine.
There is a crankcase heater terminal on the sureswitch
Converting a 2 pole contactor gets tricky. I spent hours on a roof trying to figure that shit out. (Not all units are wired as the diagram shows).
oh is a letter, zero is a number!
Do they have a 3 pole contactor or just single?
Would this work with a Micro-Air soft start?
Any advantage using this with a soft start?
It does it's own version of a soft start by starting in the middle of the ac wave. A soft start would be redundant.

Well done
These have been available for a few year and haven't taken off like they really wanted them too. Has anyone seen them in new units?
I switched from residential to commercial, but this is the first time I'm seeing them.
Those are great investment
👍
Don’t like the one through contact.
But it is good temporary “rescue”, until come back with OEM deal.
Many OEM contactors are 1 Plus or single pole, just like this.
It's a fucking relay .
These make pump downs annoying

“Ubiquitous” : Found Everywhere.
For those of us that talk normal.
Not for $50.
I will pass. Only for emergency use only. Waste of circuit boards if you ask me. Puting a dress on a pig.

Sounds like one of those upgrades I was pushed to sell doing residential
