annoying light flicker when heat pump starts up

My Geothermal Heat Pump [Waterfurnace Model EW042R1SSA] causes an annoying light flicker and some noise when it starts up. Can I do a retrofit to remove this issue?

Interesting. This also appears to lessen the required size of a generator during a power outage.

Assuming there is not a problem with EW electrical, this should solve your issue. The Intellistart is a soft start device designed to cut your LRA by 60%. It can be installed any unit with a scroll compressor, 2 stage or single stage. Age should not matter.

Thanks, looks like a winner. Any idea on pricing?

Well, let's order two and split the cost, OK?

Looks promising.

I'd like independent corroboration of reduced amps. If the thing works as advertised it could save thousand$ of standby generator dollars.

My own Waterfurnace has a nameplate LRA of 82, which contributed to my selection of a 24 KW 1800 RPM standby generator. After that 82 LRA spike my WF settles down to using 6 amps in cooling, 8 amps heating in low stage.

The 6 amp WF hits the generator harder (judging by ear) than my 5600 Watt clothes dryer...

Anyone order one of these yet?

I'm definitely interested and am curious about cost and results.

For Copeland to mate a Scroll compresor to an ECM drive.

Variable speed compressor will be the next big leap for GEO.

I have installed intellistart and would recommend it for cutting LRA. Also a relay and capacitor from Copeland (sized for your compressor) would help.
