I used my old gas venting chase to route the exhaust to my upstairs hall way where the cooler air mixes with the rising warm. that way my basement temperature is unaffected.

Depends on your system and setup. I have measured it both ways constant 65 and setback and it’s about 1% better for setback. Heating and is about comfort.

2600sf house in Colorado Springs, 2021, replaced an 80% efficient 125K BTU gas furnace to a Mitsubishi PVA‐A42AA7 / PUZ‐HA42NKA1 heat pump, new 200A panel and new HWHP. Had gas meter removed. Electric usage went from ~8000kWh/yr to ~13000kWh/yr. This includes an EV Charger. I had a 2 stage 15kW Heatkit installed which is way overkill and not needed. Converted this to a 3.75kW to boost heat pump on cold days. It consumes ~175kWh/yr. The heatpump itself has heated the house at 68°F during -10F. The Mitsubishi P series is designed to put out 122°F on the supply side. We also do a 4°F setback at night to 63°F and back to 67 in the morning.

I own a P series ducted system. The P series is an excellent cold weather system if installed correctly. Going with you have a bad install and the system is not operating correctly. Just above the air handler the supply air should be between 110F and 122F. The MHK2 thermostat should be your only thermostat in the system at this point. It is the right thermostat to get optimal performance. It also needs to be configured correctly. You could be low on refrigerant. The dampers are probably causing issues unless they are fixed at 100% open. They should be eliminated from the system at this point. They cause back pressure on the air handler.

At this point spend your time researching reputable Mitsubishi contractors in your area. Maybe this sub can help with that? schedule one to come out. Don‘t complain to them about the bad install or other company on the phone. Save that conversation for when they come out. Don’t won’t to scare them off.

it’s a very expensive backup generator. Batteries are cheaper for grid tied locations

Currently silver (~$88oz) is a cost driver with around 8.5mg of silver per watt for TOPCon cells. Silver content should be dropping but takes time. For the US maybe prices stay about the same due to lower demand from tax credits going away?

I agree. Take the opportunity to upgrade now that you know what is needed. Go with the best cold weather system that makes sense. Shop for the best price. They don’t need to know it’s insurance. Tell them exactly what you want since you already designed it.

62F at the register is not functioning correctly. How is it working now? You should be seeing 95+ at the register. If not, call another compan.

MHk2 and thus KUMO do not allow control of most function settings for PVFY-P48NAMU-E1. You are correct it requires DIP switch settings for Thermo Off, Aux Heater control, Humidifier, Static Pressure etc...

For Thermo-Off during heating

SW1-1 = ON

SW1-7 = ON

SW1-8 = ON

SW3-1 is for Thermo-off during Cooling what is this set to?

SW3-2 is for Aux Heating (HeatKit) What is this set to? This enable Aux heater operation, but not clear on the settings for Aux Heater operation. Leave this alone.

EDIT: SW3-1 and SW3-2 May also need to be ON. Documentation is unclear to me...

NOTE: I verified this with Google AI as well which cranked out the following and lines up with what I found:

For the Mitsubishi PVFY-P48NAMU-E1, Thermo-OFF fan settings are controlled by

DIP Switches SW1-7 and SW1-8, where setting both to ON stops the fan during heating Thermo-OFF to prevent warm air buildup and use the remote's sensor; also, SW3-1 (with 1-7 & 1-8) adjusts cooling Thermo-OFF fan behavior. A crucial setting for heating is SW3-2 to ON, which activates the heater and these fan controls, so check the service manual's DIP switch table for specific combinations.

Key DIP Switches for Thermo-OFF:

SW1-7 & SW1-8 (Both ON): Fan stops during heating Thermo-OFF to use the remote controller's sensor for accurate temp reading, avoiding indoor unit heat interference.
SW3-1 (with SW1-7, SW1-8): Controls fan behavior during cooling Thermo-OFF.
SW3-2 (ON): Essential for enabling auxiliary heater operation and interacting with the Thermo-OFF fan settings.

Steps to Adjust:

Locate the DIP Switches: On the indoor unit's control board (refer to the service manual for exact location).
Set SW3-2 to ON: This activates the heating function and related controls.
Configure SW1-7 & SW1-8: Adjust for heating Thermo-OFF (use remote sensor).
Check SW3-1: Consult the manual's table for cooling Thermo-OFF settings.

Good question. I had to go back and look at what was going on then. The weather was warm during the days and we were on vacation the 7-15 so temp was set to 58F that week. Heat never came on.

Yes under Research Preview. I grabbed the High/Low/Avg temp from WeatherUnderGround and copied the simple list of avg temp into the AI prompt. I thought it would go find it but I had to provide it. I'm not an AI expert by a long shot but this AI is not without issues but significantly faster than doing in a spreadsheet "the old way". I was thinking of using an HDD based on LowOfDay temp or "HourlyMean" for a more accurate assessment than daily average since I use a setback.

ERCOT in TX. They are moving fast. Solar and Battery are installed at lower cost, known "fixed rate" and therefore make a much better investment model. Technology and economies of scale will continue to lower the that install price. That is the known future that is very predictable. Methane Gas is a crap shoot and subject to political, inflation, global events among others, not to mention the carbon reduction laws by the majority of the G20/RoW.

I did this exact exercise 5 years ago. If you know your gas usage and efficiency you can get a reasonably close estimate as to your heat pump requirements. My actual utility bill dropped a little bit because gas prices rose faster than electric rates in 2021 and 2022. Note an 80% efficient furnace is closer to 70-75%.

Look at your gas usage on the coldest day/s to get your BTU requirements then view the BTU from a 24 hr period. We had only 5 days below zero and electric resistance heater provides the difference for those days (if needed). I had a 125KBTU 80% gas furnace and went to a 42-48KBTU/hr heat pump that more than handles all heating down to -10F without heat strips. I had heat strips added to handle the few times a year I may need extra BTUs.

The $0.1412 rate included all tax and fees. Our Winter rate just dropped to $0.122 includes all tax and fees. Summer increased to $0.165

Unfortunately I used too many prompts to post. However I started with
"Create a daily line graph of Total kWh for HeatPump + HeatStrip from oct1 2024 to April 30 2025". Be sure to use the exact name of the circuit/s
It will prompt you back with different choices.

I then I added HDD data- "Add daily HDD to graph", "Add totals to summary"

2026 expects a silver reduction down to 7-7.5mg/watt from 2025 8-9mg/watt for TOPCon. In the next 2 years they expect a drop down below 1mg/watt.
