1) I've read that when monitoring a single channel, using a Micro-50 for example, that the orientation should't matter. However, I'm seeing a difference when I reverse the leads. One one circuit I was seeing ~26W, but when I switched the white & black it dropped down to ~18W. Is there any explanation for this?
2) I'd like to combine three 240V circuits used for my heat pump system into a single channel. The three circuits are as follows:
Heat Pump Outdoor Unit (uses neutral) with 2x Micro-50s installed
Air Handler (no neutral) with 1x Micro-50 on one leg
Aux Resistive Coil (no neutral) with 1x Micro-50 on one leg
I think I know the answer to this, but is there any clever way to double the AH and coil circuits and combine them with the two legs of the heat pump all in one channel? Or should I just use 2x more Micro-50s on the AH and coil and put all 6 in parallel?
3) My system is split between two 150A subpanels. When I installed the Split-200s I put them all in the same direction (arrow is K->L for all four). I'd like to combine them into one channel. Is this the correct wiring:
CT1 = Panel 1, Line 1; CT2 = Panel 1, Line 2; CT3 = Panel 2, Line 1; CT4 = Panel 2, Line 2
Pin 1 <--Blk--CT1--Wh--> <--Wh--CT2--Blk--> Pin 2
Pin 3 <--Blk--CT3--Wh--> <--Wh--CT4--Blk--> Pin 4
or is it better to:
Pin 1 <--Blk--CT1--Wh--> <--Wh--CT2--Blk--> <--Blk--CT3--Wh--> <--Wh--CT4--Blk--> Pin 4
Thanks in advance!
