Sounds like a bunch of made up crap!  Too bad they feel the need to make up such false bs, besides making them look like completely dishonest shysters it hurts the EE industry as a whole.  I own and like the product, but these people embarrass me.Photo: GD's Ecobee - now that he's got his old HP running.  Wow, some recovery!  Setback at this temp clearly reduces cycling.Photo: Photo: Photo: Photo: Photo: COLD!!! But this is still GROSSLY oversized.Photo: COLD!!! But this is still GROSSLY oversized.Photo: COLD!!! Looks like my water temps aren't high enough.  Backsliding.  Put fans to radiators at noon.Photo: COLD!!! Water temperatures to these radiators seem adequate, although recovery is slow the bump points are to insure heat in floor and rads at occupancy, not really for "recovery".Photo: Fairly deep retrofit on this house recently.  Think furnace might be grossly oversized on coldest day?Photo: Fairly deep retrofit on this house recently.

Playing with settings attempting to reduce cycling and understand performance.Photo: 4 stages of heat, 2 for furnace 2 for heat pumpPhoto: Photo: Having put whole house on one boiler, it appeared I might not have enough heat on very cold days.  I experimented with water temperature settings then discovered I could change the pump speed.  Changing pump speed from 1 to 3 dramatically impacted output.Photo: Program for the boiler in my house.  I bump it periodically to insure the radiators don't go completely cold or swings can get unmanagable.Photo: "It's just so comfortable"...Photo: This is a mfg facility that's closed Sundays. Ecobee controling low efficiency radiant tube burners. Check out the short cycling to keep level, one pull to come up off setback, similar short cycling when up, then a float period.Photo: This is a warehouse/mfg facility with in-floor heat.  Ecobee must think unoccupied means go to 45.  Maybe it learns better over time, but that seems to start at stupid out of the box.Photo: Not Keeping Up!!!  I removed one boiler and turned my house into the mythical unicorn!  Cleaning the HE helped a bit!Photo: Dirty HE + design load = SLIPPAGE!Photo: Oooo, don't like that short cycling in the wood shop.  Set a 2° delta and hammering on the equipment stops.Photo: Photo: burt - NOW we can have PROOF that 60k carries this huge house...Photo: burtPhoto: Burt home ecobee installed.Photo: changed anticipation delta from .5 to 2° - get much more steady run cycles.Photo: Ecobee set to shoot for humidity target too - calls for fan to run...Photo: Burt on 0° dayPhoto: Psychrometric chart - Temperature change and it's impact on Relative Humidity.Photo: Photo: burt - twins staged and programed for a little comfort bump in the AMPhoto: burtPhoto: Photo: Wow, low stage seems to carry really well!Photo: burt, 60k satisfying at 20f!Photo: Burt Project.  Wow, holding 69 at 8f!  Took 1000 cfm50 out of this house - both homeowners commented on comfort improvement and one furnace holds temp to almost 10° colder than before.Photo: Nate Adams Brochure showing leverage - s curve net costPhoto: Wow, not much High at that temp unless call for higher temp.  Not sure why high is staging on the 26th or 27th - there is no call.  Logic algorithm confused?Photo: 1 degree outdoor temp, only reason for high stage is my "morning bump".Photo: Burt - vaca - asked to lock at 67Photo: Nancy Downstairs unicoPhoto: Nancy upstairs unicoPhoto: Cognitive dissonance.Photo: ems interface - parson's up.Photo: Parsons Boiler - Sensors added to supply and return pipes 1/16Photo: Test out auditor forgot to turn off furnace, rollout tripped safety, call for heat next day went unsatisfied...Photo: Nate Adams Brochure showing leverage - s curve net costPhoto: Parsons - New Building HP installed.Photo: Burt, hot day, new equipment. Dehu energized...Photo: Burt, not sure what's going on here...Photo: burt newPhoto: Burt oldPhoto: Parson's new building.Photo: Parson's hvac startPhoto: Parsons - cooling below setpoint so cool to dehumidify occuring.Photo: John Burt, set to reverse stage, dehumidify to 45%.  Dehum doesn't appear to be running here...  Called Ecobee, Probably should turn cool to dehumidify off but have to go to the stat for that.  Trip time and crappy touchscreen make this annoying and expensive.Photo: burt, got dehu running!Photo: Photo: Hmmm.  Humidity not dropping with AC and Dehum running!  Airflow too high across the coil on low stage??Photo: Dehum turned on aug 26 and set to 42% AND reverse staging to get longer ac run (run more on low) doesn't seem to be having any noticeable impact on RH.  AC on high stage has temporary impact on RH.  Equipment not set up correctly?  Not sure what scuttle is doing.  Not sure what continuous fan is doing.  Will try setting fan to auto...Photo: Burt Dehum running continuously from 8/26 - yet look at RH!!  Stopped continuous fan at noon, and still rh goes up!  AC is running "cool to dehumidify (running below setpoint) and STILL not much dehumidification happening.Photo: Parson's New Building AC - can almost see when they open garage doors by watching RH spike.  Can see "cool to dehumidify" when cooling temp is satisfied.  Can see when temp backslides but humidity keeps getting nicer.   You might not think so, but apparently the place is really comfortable and this outcome is a great success.  Lot to learn from this.Photo: 57° dewpoint, dehum running continuous since aug 26 - turning fan back to ON.Photo: fan from on to auto 8/27 noon.  back to fan on aug 28 10amPhoto: Dehumidifier not showing a call for dehumidification, what's up with that??Photo: ideosyncratic dehumidifier operation, ecobee problem??Photo: ideosyncratic dehumidifier operation, ecobee problem??Photo: burtPhoto: burtPhoto: burtPhoto: burtPhoto: burtPhoto: parsons new heat pumpPhoto: New heat pump working nicely. Still haven't had to run the boiler.Photo: AmosPhoto: AmosPhoto: AmosPhoto: BergPhoto: BergPhoto: BergPhoto: Berg upPhoto: Berg upPhoto: Berg upPhoto: Photo: burt - bumped to aux? Humidifier fixed?Photo: Burt - looks like 5 ton HP is about maxed at 40fPhoto: Burt humidifier doesn't seem to be having any impact.Photo: Burt kicking to gas (aux) heatPhoto: 5 ton backsliding to where aux kicked in - burtPhoto: Stage 1 carrying the house, then a comfort issue bump to stage 2 - burtPhoto: Burt humidifier seems to be having no effect.Photo: Burt - 3° slide before aux is too much...Photo: Burt over thanksgiving.Photo: Gardin, big recovery - ecobee logic handling based upon target.Photo: Gardin, big recovery - ecobee logic handling based upon target.Photo: Boiler shutdownPhoto: Boiler shutdown...Photo: What is this? They leaving doors open??Photo: Heat working upstairs.Photo: Burt. Seems slow recovery - furnace ramping up or locked on low?Photo: -8!! I did put a fan by a radiator, but house is comfortable.Photo: John Burt, good illustration of house performing at various stages and outdoor temperatures. It looks like below 35, high stage HP doesn't carry the house. I think setting HP lockout at 40+ makes sense...Photo: Outdoor reset needs to be adjusted down for warmer weather?Photo: Outdoor reset needs to be adjusted down for warmer weather?Photo: Photo: Photo: Changed boiler settings. OD Reset showing 22f not 8! Removed cap, still off by 10 degrees. Bad location for sunny, still days. Need to move under front porch. Ramped reset curve, min boiler temp and set "boost" to boost supply after showers. Supply going out at 127 instead of 119.Photo: Photo: Photo: Photo: Photo:
