I have a GeoSystems Mega-tek heat pump and the associated Banana service tool, which is used to read a host of data such as water temps., lockout log, I/O status and compressor run hours.  The problem started when I decided to start a written log of compressor run hours and discovered that the system (cpu or moboard) is resetting the compressor run hours every so often.  The Banana operations manual clearly states on page 12 "Note: The compressor run hours cannot be reset."
I contacted my installer who said he would contact GeoSystems and he waited and waited and received no answer to the problem.  I contacted GeoSystmes and received a letter stating we will not fix it under warranty. I then wrote the CEO/President Larry Olsen of the problem and he sent me a letter stating "the run log has no effect on the operation of the heat pump and it is not covered under warranty." My response was the system does not meet factory specifications, since the operations manual clearly states run hours can not be reset and the unit is defective and should be repaired.  I reasoned that much like a cars odometer, which has no effect on the automobiles operation it's function is to record miles and if it automatically resets itself it is not meeting specifications and should be repaired under warranty.
So.......the bottom line is they choose not to fix the problem!  There are probably lots of systems in the field resetting run hours, their owners don't have a way of checking the run times. It is my opinion that GeoSystem's lack of customer service by not making an effort to fix their problem is reason enough not to consider them when it comes to purchasing a geothermal heat pump.
FYI the unit arrived from the factory 4.5 lbs. low on R-410a how it got through quality control and passed is yet another question that was never answered. 

Unsatisfied GeoSystems Mega-tek Model# MT4V061XL-N-15 owner anybody else experience this?

While it seems kind of crumby that they won't fix it, I don't get the excitement. No one knows operating hours on their compressor and it is not a useful diagnostic tool.

If your reason to recommend against the megatek is you can't tell operating hours then you'd have to recommend against every brand of equipment. I doubt manufacturer intended for homeowner to by a banana without which you wouldn't even know it was acting up.

So to use your scenario it would be more like the hidden odometer failed on your car. A car manufacturer wouldn't likely fix that either.

If it is really that important to you, a check of state warranty laws might require repair.

Arriving 4.5lbs low is the bigger problem. You might have a leak there. Here's hoping that's all that goes wrong with your Hydrodelta.

Good Luck,

David, I suspect that you have spent more time calling and posting than it would have taken to just buy a Hobbs/hour meter and install it.

...the system (cpu or moboard) is resetting the compressor run hours every so often.  The Banana operations manual clearly states on page 12 "Note: The compressor run hours cannot be reset."

I wonder if this just means that the user and installer cannot reset the run hour meter (but the CPU can reset itself when the programming tells it to.)  Are the conditions immediately before a reset always the same (in terms of accumulated hours, etc.)?

We may have lost David. He brings up an interesting broader topic of customers" hands on.
In a case of the banana for instance which is basically a dedicated diagnostic tool (I asked a rep more than a year ago if they were gonna sell software for laptops so we wouldn't have to drop 5 bills on a "banana"), one can change a few presets in the equipment and clear histories, it is not really a homeowner tool.
I would submit that measuring ewt's, lwt's, eats, lats, checking the filter, hooking up a TED or WEL server etc. are about as deep is I want my customer into the job (to avoid muddy water if I go out).
I would be put off by a customer who wished to buy their own diagnostic computer. Frankly my impression would be that all warranties were void as soon as someone other than a manufacturer's trained agent hooked the banana up to the thing.
Not trying to bust David's chops, but really, when I buy a new truck, I don't buy a diagnostic computer at the same time, in fact I don't do any maintenance or repair myself during the warranty period, I leave it in the hands of the factory certified technician.
Many of us spend a lot of time here trying to be helpful to people having problems, but in the last couple days I've seen shrill posts with exclamation points that make me wonder if we educate folks too much or not enough, 'cause some are definately caught in the middle.

Joe,

It's not about the banana or the customer, it's about the unit not meeting manufacture specifications.  There are probably lots of Mega-tek systems in the field resetting compressor run hours and who would know unless you had a service call and the tech made a note of run hours.  As far as I know, you can't change presets and clear histories with the banana, I have the operations manual and see no way to change presets and would not want to, I just want to know common system info like ewt, lwt and compressor run times stage 1 and 2.  I could add a hobbs meter for run a times, but why should I have too, the system is designed to record stage 1 and 2 run times per the manufacture.

Not that it matters, but I am an electrical engineer and since I purchased the unit and it is in my basement, I should be able to look system info using a remote terminal (banana) if I choose.  Sorry your put off by a customer who wants to look at system data, I feel many geothermal users are like me and want to know water temps, lockouts, calculate COP, etc.  It's not rocket science to plug in the banana, it uses a standard phone plug at one end and a DB9 plug at the other, the key pad is straight forward and it's operation is very easy, even a factory certified technician can do it!  Your not busting my chops you just have an opinion, if you don't want to hook a scan tool to your new truck that's your business, lots of gear heads do, so they purchase auto scan tools.

My request is that GeoSystems fixes the compressor run time hours reset issue so my system meets factory specifications, nothing more nothing less.  Geosystems refuses to fix the system, which is still under warranty and that is poor customer service in my book.  Even my installer said the problem should be fixed and has dropped the Geosystem line of products, for reason such as this.
