I would be shocked if they were not already planning to do this. This is a fantastic product but ease of installation is important.
You must be a clairvoyant, HD Pilot. Thanks for your compliment, and indeed, we are in fact working on a smaller, less expensive model for 115V RV applications only, that will fit into just about every rooftop electric box. It's still a few months away from completion, but as we like to say in the big electronics product development business, "you have to obsolete yourself before someone else does".

Other than colour, what is the difference between the old "black" control and the new beige one. Is there a size difference?

It is my understanding that the only difference is in the case (e.g. Same electronics inside). The beige one is a little bigger than the black one. Also, the beige one is more weather-resistant.

After Startup?

Does the Easy Start continue to function after the initial startup?
Thanks

I gather the Easy Start's main purpose is to lower the startup electricity draw. Electric motors draw much more current during the first second or so it takes to accelerate to their operating RPM. Once at speed their power demands drop. In the case of the Airstream AC, after this initial draw the current demand drops to a level a Honda or Yamaha 2000 can sustain operation. So my guess the answer to your question is no, the easy start does not add functional value once the AC has started.

EasyStart's Benefits During Steady-State Operation

Quote:

Great question, SilverSinbad. In addition to EasyStart's dramatic reduction in the compressor's startup current, it does also provide very valuable benefits after the startup is completed. As kscherzi mentioned, once the startup is over with, the EasyStart does not electrically affect the compressor's normally operating (steady-state) running current since the EasyStart's solid-state power devices have been switched out of the circuit and internally bypassed by power relays. However, during steady-state operation, EasyStart continues monitoring your compressor's AC input power, real-time current, and motor rotation. It continuously checks for anomalous and potentially damaging conditions, and it will very quickly intervene to shut down the compressor much faster than any of the other factory-installed protection devices (e.g. high pressure switches or thermal overload protectors).

Below is the list of these benefits. Each has a corresponding fault LED light sequence that shows on the circuit board. If any of these conditions occur, the EasyStart will wait 5 minutes before attempting another compressor restart. This waiting allows the internal refrigerant pressures of the A/C system to equalize, thus preventing stalls during any subsequent restart attempt.
  • Stall Detection - If the compressor stalls for any reason (low voltage brownout), the EasyStart will detect this and immediately shut it down. Without EasyStart, the only protection for this that exists is the compressor's thermal overload, which typically takes about 3 seconds to react. Also, the system's circuit breaker may not help either if it is set too large or the voltage is low enough to keep the stall current within its trip setting.
  • Overcurrent Detection - If the compressor exceeds the steady-state current rating of the EasyStart itself for more than 5 seconds, and if the system's circuit breaker doesn't intervene, then the EasyStart will shut it down.
  • Open Overload Protector - If the compressor's thermal overload protector opens for some reason (i.e. compressor overheated), the EasyStart will detect this, shut down, and wait 5 minutes before restarting, even if the thermal overload immediately recloses.
  • Wiring Error - If you install the EasyStart incorrectly or a wire comes loose during operation, EasyStart can detect most wiring errors and completely inhibit any starting attempt at all at all.
  • Power Interruption - If AC power disappears for even 50ms, which is often enough for a compressor to stall (since they don't "coast" very much!), the EasyStart will detect this short outage and wait 5 minutes before attempting a restart.
  • Anti-Short-Cycle Timer - If the power completely goes away or the thermostat becomes satisfy and turns off the compressor, the EasyStart will keep track of the off time - even while power is completely removed from it - and require a minimum of 5 minutes before attempting a restart. For example, when power is reapplied and/or the thermostat calls for the compressor to run again, if only 3 minutes have elapsed, the EasyStart will wait 2 minutes more (i.e. the balance of 5 minutes) before restarting the compressor. If more than 5 minutes has elapsed, then the EasyStart waits its usual (minimum) 5 seconds before restarting the compressor.

So, as you can see, the EasyStart provides tremendous benefits and protections for your compressor well above and beyond the factory configuration of any RV rooftop A/C in the industry. Hope this helps.

I hooked up my H2000 today and ran for 30 minutes without AC checking out low draw things in the AS. The reason was my new Gen had a bad spark plug that caused problems the day before. New plug in, ran 30 min and all was well. Turned on AC, it didn't do anything for a few minutes but then fan came on and a little while later (I didn't time anything) the compressor kicked in. I had to listen really hard to hear it. Let it run for 20 minutes then set therm up to cut off AC. Gen went back to Eco and it ran pretty smooth. Turned AC back on and it worked again. Happy with both the easy start and the new gen. Guess there may be delays on start up that don't mean anything is wrong, it's just getting its ducks in line, lol.

Thumbs up Free EasyStart Stickers!

A brilliant idea from an Air Forums member was passed along to me, and I went ahead, designed, and got printed an outdoor quality sticker that you can adhere to the side of your A/C, trailer, or wherever. They're 3x5 ovals, in the popular style. If you'd like some, please PM me your previous order #, how many you'd like (limit 2 per A/C), and I'll mail some along to you on the house . Thank you again for everyone's support!

I installed the Easy Start on the 15K AC today.
One Honda 2000i was able to start and run the AC along with a few lights and the fridge on.
There was no need to drill any holes.
The wires from the easy start just follow the compressor wires.
I left the unused cap in place.
When I get home I will solder the connections because I am paranoid.

Outstanding work, Randy! In parallel with you, I actually discovered and did what you did on 7 installations over this past weekend at an RV rally in Tennessee. Clearing the duct putty out of the way to pass the harness through the existing hole and reapplying it was much easier, and much less intrusive. You took it one step further by even eliminating the need for the tie-wrap anchor. One question: How close was the harness length? Were the wires bordering on being too short after exactly following and tie-wrapping to the compressor wires?

In any case, in response to your post and my experience, now that dozens of Penguin IIs are out of my reach again, I've asked my team in the factory to do what you did in our Penguin II and retake some more photos. I'm also going to see if we can redesign the installation kit to eliminate the liquid tight and tie-wrap anchor, and add a few more tie wraps. That'll save a few bucks on the price. Lastly, I'll make a one page sheet to add to it, specifically for the Penguin II, so we can show this method more clearly.

Thanks again for sharing. We're always looking for ways to make EasyStart installations better and easier, especially for what now seems to be the ubiquitous Dometic Penguin II.

The wire length was just right.

EasyStart UpDate = ESUD.
While attempting to run two ES modified air conditioners on one Honda 2000i generator, the Honda never went into an overload condition. Rather the AC fans would operate without the compressor.

In fact at anytime the AC was short on current only the fans would operate.

What this means is if your not getting cold air, and the fans are running, something else is drawing too much current. It could be your converter or your water heater or whatever.

It was interesting that the ES modified AC compressor would turn off faster than the Honda overload circuit could engage.
