And why are we bring back a post from April for something that's already been fixed?!

Typically done through carrier current signalling, where they impose a high frequency data signal on the power lines to signal equipment within the household and vice-versa, this is also one of the...

I see no point in letting the PoCo cut off my A/C or H/P during peak periods, especially if my condensing unit is properly sized for the load... It would now take a lot longer for it...

Had a Honeywell digital stat do the same thing (RTH5100 type stat), one of the pins on the back had come loose (pin was stuck in the sub-base when I removed the t-stat). Was able to resolder the...

How have you configured the zoning panel to 'stage-up'? Is it set to do it via thermostat demand, timer, % of thermostats calling? Are the strips configured in the panel as e-heat or as...

Nissan/Infiniti has been doing it for some time now also... I believe VW even has one that will destroke to 0% and does not even have a clutch...

Anybody else notice how close the condensing unit was to the gas...

As was stated by SBKold and others, it's just the liquid refrigerant boiling off.

That's a 'Liquid' line drier, therefore it is full of liquid refrigerant, you are boiling the refrigerant out...

Nearly all of the server and UPS manufacturers these days have a spec listed for max heat produced in BTU/hr in their literature. If not, you can make a rough guesstimate based on the power...

You don't suppose someone left the shipping bolt in the compressor mount in that Envision do you?

Yeah, good luck selling it, most places I know only see the initial investment $$. I know the inverter units can be nearly wisper silent, even with the compressor running. We've got a Samsung...

Umm, in heat mode, the flowcheck in the indoor TXV/piston shuttles to bypass the indoor expansion device in order to maintain a full liquid line back out to the heat pump. It then uses the outdoor...

Huh? Ambient temps hit the 70s, house gained enough heat to cause thermostat to change over to cool and compressor sounded unhappy...

Sorry previous post was incorrectly worded, A/C was not run...

Outside temps have been in the 20's since it was last run (this weekend). Unit is 2 ton and not factory equiped with a crankcase heater, was wondering if one would be suggested or if the scroll...

Ambient temp is about 72 degrees, system switched over to A/C after heating for the past couple weeks, first startup sounded like the compressor was gonna jump out of the condensing unit, then fine...
