Has anyone experieced code 4 lock out?  We are currently trying to fix the problem.  We have been flushing my 2 500' wells and are getting some air in the loops.  We are circulating at 15 gals per min and have an EWT of 50. 

This is the initial start up of the system and we just added 45 gals of antifreeze.  I have been running on aux electric heat for a week now while we try to fix the problem.

I called Climatemaster and talked to a tech.  I heart of bad sensors out there but he said they were on the older units and mine is new and shouldn't have the problem.  He said he thinks it is air in the loops.  We will tackle it again tomorrow, wish us luck.

Good Luck,

what pump are you using to flush with ?

scott
verify your feild config /thermostat wiring with your manuals section relating to cxm controls and unit start up
a dip switch here a jumper there take you time youll find it
with 50 ewt i doubt some air is your problem

Are you using a flush cart to purge the wells of air

sorry loops not wells

Thanks for the replys.  It seems like I have inexperienced Well and HVAC companies.  I am doing all the research on the system and I am learning that my contractors don't have a clue.

My well guy flushed the system when he was done installing the valves into the house.  The flow circulators were not installed yet so I assume he didn't get a proper purge. 

While I call Climatemaster and do the research I realize that the proper way to flush and purge the system is using the flow controller circulator pump inlet and outlet valves explaned in the circulator manual.  - How do you turn the flow valves?

 

My well guy is coming tomorrow morning and I doubt he has a flush cart.  I assume we can get it done using a garbage pail and a pump.   I am turning into the GC of the job and  trying to overcome incompetence.

P.S.  I also learned that the polyproplene glycol antifreeze that my contractor put in  isn't  the best for heat transfer,  I guess I'm a little to late on that one.

Wish me luck.  Will update soon.

You will not be able to remove the air from the loops without a flush cart type pump. You have to move the water through the loops very quickly and forcefully to remove the air.

Any 2 horsepower pump will probably do the trick. Just make sure that you run to flow both ways through the loop.

Scott, what size is the loop down the 500' wells?

1 1/2 inch loop  approx 2100 ft , approx 420 gals.  We added 45 gals of antifreeze.

Scott, you need a pump that will push at least 26 gpm against 35 ft of head in order to properly flush your system. Be sure and go both ways through the loop.

SUCCESS!  Thanks for all the help!  The loops are purged and we did it with a 1/2 hp pump.  We hooked up a pressure tank and the system is pressured to 50 psi. 

 

Now my next question.  Is my compresser a one or two stage?  I have a Honneywell circuit board and it asks if it is one or two stage.  I thought it was a two stage, but I'm not sure.

 

I think this is how it works, correct me if I'm wrong.

1st stage = low fan

2nd stage= higher fan

3rd stage= high fan with aux electric heat

My circuit board is only telling me that it is going in 1st and 2nd stage but it won't tell me if the aux heat comes on.  I can only know it is on by the DATS.  I have 2 zones and conventional  Honneywell T stats. 

 

My contractor says I don't need the heat pump t-stats because my honneywell circuit board will do the job.  Is this correct?

 

tranquility 27 is a 2 stage heat pump

Yes I understand, but is my compressor one or two stages?

Single compressor capable of pumping refrigerant at two different rates providing 70% capacity in low stage and 100% in high.

Compressor speed and sound does not change, rather a solenoid opens / shuts a bypass valve allowing some of the refrigerant to escape being compressed.

Compressor speed can change on the fly.

Thank you for the replys.  I set it properly now and it is going through all 3 stages as its supposed to. 

 

Thanks again!
Scott

I can't believe I missed this post.  This is exactly what I am having problems with.  Code 4 on a climate master unit.  I have been having this problem for 4 years now.  (code 4 is freeze protection, water coil).  My question is what the heck is causing my ground loop to give out every year?!?  It worked flawlessly the first 2 years and now is crappin' out every major temp drop.  That is to say mild shoulder season weather to 30 degree F drop in a 24 hour period that demands heat.  jeez... tons of typing ahead..  bear with me.  First year at Thanksgiving.. temp dropped to a pretty cool temp and I heard the compressor drop out after about 30 seconds. ??? I knew that wasn't right.  Well I figured out that the code 4 set.  Called the installer and he sent out a rookie GSHP guy, actually didn't know diddly about them.  In his defense it was a holiday weekend/week and was a real nice guy, just can't get it solved.  Anyway the owner has been out twice since then and flushed the loop twice to fix the same problem at different years.  A long time problem anyway.  One of my many questions would be is what would allow the ground loop to deteriorate to the point it needs to be flushed after every year?  And I am not kidding when I have a million questions about all of this.  I'll start with that one.  I would give a nickel to visit with a knowledgeable installer/maintenance man to pick his brain and not have to type all this out.  Let's hear your thoughts please...  Joe

I'm really sorry.. too many margaritas..  A little more info on my setup..  a CXM control on a single stage GT-G compressor with desuperheater and a single Grundfos UP26-99 f loop pump with three 200 foot vertical geowells (1200 feet total?).

Joe, What size is your heat pump?

When you flushed the loops did you pressurize them to at least 50 psi?
