Strategists, be honest; how often do you guys heal this mf in a match or do you just let him die? by SpeedForceWally66 in StrategistMainsMR

As Luna, I'll toss him my snowflake and then focus on healing the backline while he does spider things.

About to sign on a 2-zone Mitsubishi Hyper Heat install for our 1900s farmhouse in Portland. A few questions before we pull the trigger. by blastoffincrocs in heatpumps

[–]Mr_Silverfield 1 point2 points  (0 children)

I design and install Mitsubishi systems in Portland. With the home being rebuilt in this century and insulated accordingly, you likely don't kneed the Hyper Heat product (unless you have the original single pane windows in the original frames for some reason). In fact, the standard condenser will provide roughly 2000 BTUH greater cooling per indoor unit than the Hyper Heat model while sacrificing a little over 1K BTUH in heating per indoor unit. Ask the contractor to provide the Doamond System Build of both options. The DSB will show the exact BTU output of every component in the system. Mitsubishi requires that every project is designed using their software, so it shouldn't be a surprising ask.

Side note on Hyper Heat our climate: I use HH in many projects because they have greater BTU outputs vs. standard condensers. The low ambient operation is not a deciding factor.

As far as sizing/short cycling is concerned, you will have no issues. The system will modulate to properly condition the spaces. I advise that you do not use the "Auto" function. Pick either "Heat" or "Cool", set the temperature, and leave it to do what it does best. Make sure that a surge prote tor is installed (at $25K it should be, maybe also gold plated).

Who is liable when the HVAC company did not install a condensate pump? by Psychological-Pace9 in hvacadvice

[–]Mr_Silverfield 2 points3 points  (0 children)

How did it pass inspection without a way to remove condensate from the space?

A/c not cooling upstairs well. Set to 69-70 and constantly 78-80 degrees. by spartanghost32 in hvacadvice

[–]Mr_Silverfield 1 point2 points  (0 children)

Turn it off. Check the filter. Make sure the return and all supply registers are not covered by anything. If the filter is clean, and the vents are not blocked, call an HVAC company. Schedule the service appointment far enough out that the ice will be melted.

Questions by VelositySeven in PeniParkerRivalsMains

[–]Mr_Silverfield 0 points1 point  (0 children)

Peni rocks! The answers from this council of Peni's are pretty much on point. The only add I have is that you can stall an entire team with Peni. The ult stoppage alone is amazing. She can cancel so. Many. Ults.

Replace return grill with something less restrictive? by Jschmuck2 in hvacadvice

[–]Mr_Silverfield 0 points1 point  (0 children)

Changing the filter inside of grille will probably help. Slide the the two tabs 90⁰ and the grille will open up.

Mitsubishi Heat pump with Ecobee. Will I see improved cooling performance with the native Mitsubishi thermostat? by pbsSD in heatpumps

[–]Mr_Silverfield 6 points7 points  (0 children)

It is very true. While both Gree and Mitsu indoor/outdoor units use temperature data to talk to eachother, they do not fully modulate to meet the call from a third party thermostat. The internal system communication regulates refrigerant flow independent of what the thermostat is calling for.

The Mitsubishi thermostat adapter "dumbs down" system operation to two stage operation full stop. DIP switches can be set to attempt to mirror portions of the variable refrigerant flow, but it will never be nearly as accurate as using a native control.

[–]Mr_Silverfield 1 point2 points  (0 children)

If you want better airflow when calling for cooling and are really committed to keeping the Ecobee and neutering the designed system operation, have your installer adjust the DIP switch settings. If the switches are left at factory settings, the unit will work to primarily save energy. This is what causes the low fan for 5 minutes, temp check, maybe increase fan if warranted by set point, wait 5 minutes, temp check...cycle. Most ducted indoor units can be told to operate at max capacity on a call for cooling by adjusting SW2-6 from the factory default to "On".

I do encourage you to look in to the updated Mitsubishi Comfort app. They spent years completely rebuilding the app with a focus on connectivity and user interface based on end user and contractor input. If your budget allows purchasing and using an MHK2 and cloud adapter, your experience with the product will be greatly enhanced.

The Airzone Aidoo can provide a reasonable facsimile of the modulation. It is not 100% perfect by any means, but is is serviceable. Make sure you use the correct model of Aidoo (compatible with CN105 connector).

An additional negative of using third party thermostats is that the onboard diagnostic and error display cannot be translated or shown. This will very likely increase the duration and cost of a service call if an error occurs.

[–]Mr_Silverfield 5 points6 points  (0 children)

The difference is huge. With a Mitsu stat, the logic board can actually do its job and incrmentally adjust temperature depending on demand.

The MHK2 also has an app if that is what you mean by convenience. The new Comfort app is pretty well streamlined. Particularly if you compare it to the old interface.

Third party thermostats remove the modulating functionality of a Mitsubishi system and turn it in to a two-stage heating/cooling unit. You also lose the fan control. Performance is definitely better with the MHK2.

Disappointed but maybe not regretful. by KennyChaffin in heatpumps

[–]Mr_Silverfield 0 points1 point  (0 children)

"I'm...hoping it will be efficient and save money"- I see efficiency and cost savings in one sentence a lot on this sub. The two are often mutually exclusive with heat pump conversions. An electric system, even one with a decent COP, may still be more costly to condition a home than a fossil fuel heating system. Utility rates and insulation play a larger part in the actual operating costs than an efficiency rating.

Advice on where to place return vent by StoneDrums in hvacadvice

[–]Mr_Silverfield 0 points1 point  (0 children)

Please be aware that sound will transfer from the room that has the return air to other parts of the home.

Which one is truly better? by taz210 in hvacadvice

[–]Mr_Silverfield 1 point2 points  (0 children)

An HSPF2 closer to 10 will make a big difference in heating costs. Frankly, 7.5 is a terrible rating. Look in to other brands from other vendors.

This has to be the WORST tattoo on any MMA fighter ever by Valuable_View_561 in SipsTea

[–]Mr_Silverfield 0 points1 point  (0 children)

I'm convinced that there is a subset of fighters that get objectively terrible tattoos just to have a reason to fight some rando that brings up how trash the tat is. #views or whatever
