microair easy start results

When training the Micro-Air, would it be wise to use an autoformer to support the voltage? Or does the unit want to see voltage sag?

Is there an "ideal" voltage to train at?

Does the new 5 minute delay mean that I can "train" by switching off the air conditioner and then turning it back on in 30 seconds?

Do you have any information on using the Micro-Air with hybrid inverter/chargers such as the Magnum 3012 which are equipped with a "load support" (not voltage

support) feature? I.E. do they "play well together"?

Any idea of the wattage draw on your 15k btu unit?

Does the Micro Air do power factor correction?

1)The reason we recommend that the 5-start learning process be done on utility power is because it is preferred that the voltage not sag during the learning starts. In this way the critical measurements that the EasyStart is doing (and remembering) during each start are consistent, repeatable, and valid when compared.

2) During learning, the voltage should be at least 110V, but more importantly as stated above, it should be a reasonably consistent voltage that stays within +/-5V,if possible. Once learning is complete, EasyStart will tolerate voltage variation that is extreme, even down past the point where any compressor would be stalled out.

3) The built-in short-cycle prevention timer does allow you to let the EasyStart control the delay and set the pace during back-to-back restarts.

4) We have dozens of customers who have used the EasyStart on many models of Magnum inverter. We own a Magnum 2812 at Micro-Air (which is less wattage than the MSH3012, and is not a hybrid type), and have done extensive testing with even 18k marine units starting and running with success using the EasyStart. Solar/inverter RV refit companies use our EasyStart all the time so they can start and run A/C units even on 2000W inverters, both standard and hybrids (with load support).

5) The wattage of a 15kBTU rooftop varies between manufacturers. We own a 15k Dometic Penguin II and it has an RLA of 15.5A (fan + compressor), but we typically measure it as drawing in the 14.5-15.0A range.

6) The EasyStart does not do any power factor correction for the compressor. Once the start-up is over with, the EasyStart switches out its solid-state electronics with an internal power relay, and restores the compressor configuration to normal. The EasyStart of course continues monitoring the compressor during steady-state running for the various fault conditions it detects.
