carrier infinity with greenspeed service settings
We just built a new home in central Kansas this year, the following are some the specs on the house;
750 square feet main level with full finished basement and attached two car garage. Attic has R-50 blown cellulose over house and R-30 over garage. Walls has 3 inches closed cell spray foam main level and rim joist area. The basement and garage walls has 1.5 inch closed cell foam. Windows are all triple pane Crestline with energysheild. Doors are all energy star rated. Manual J' called for just over a 1 ton unit for cooling. But wanted the hp to handle winter heating without kicking in emergency heat strips.
The following is the heat pump system installed;
25VNA024A003 carrier 20 seer infinity variable speed w/greenspeed HP
FE4ANF002T00 carrier infinity variable speed fan coil
SYSTXCCITW01 carrier infinity Wi - Fi greenspeed touch screen
GAPABXCC1620 carrier 16 x 20" infinity fan coil air purifier
HUMCCSBP2412 carrier 12 gallon small bypass humidifier
KFCEH3001F15 15 Kilowatt hour heater with fuse
Sheet metal kit- plenum, R/A Drop, Sheet metal, ductwork
2 ton line set, fitting. Drain kit, and labor.
My question is I would like to get more details on the setup service settings. This was the second one of these greenspeed units our carrier contractor has done and showed me how to access the settings and said we would have to play with the settings to achieve efficiency and comfort levels we were happy with. First question is on the lockouts I noticed that my emergency heat strip were running allot so I set the lock out at the lowest setting 5 degrees and selected no heat strip during defrost. No lock out for the heat pump but when the system is in control it still is running heat strip as indicated on my daily energy usage. When I set the thermostat heat source to heat pump only it does not use emergency heat at all and keeps up just fine. Coldest night was 0 degrees set at 73 in the house heat pump only. Ran for about an hour than would shutdown for around 15 min and start again. I would prefer the system to be in control but it shouldn't be kicking in emergency heat if the heat pump can handle the load.
I want to get the settings set to the most efficient settings to get the most out of this system. Some my other questions is on the fan speeds min and max for the hp and inside fan. He set the compressor max rpm at 5000 does that sound right? Any benefit in moving the rpm up or down in life of the compressor and efficiency? Any other settings I can check to improve performance?
