Are you thinking of what some charge controllers call a (rebulk) mode When it will go back through the bulk/absorb stage if the voltage drops below a set value while in float?
If so then no I don't think it has that particular feature. It doesn't have any programmable adjustment of the time spent in CV - absorb stage. It's more or less. Set a float - absorb voltage and max charge limit and that's it for charging adjustment.
How long it spends at CV is predetermined by the time it took to get to the absorb voltage (with a limit on the min & max time from memory (10min / 8hrs)
I took my PIP out the other day in my Imiev (Ejerycan backup) As I had a long trip to do and wasn't sure of the capacity needed to complete it. It turned out I had plenty of capacity when I got home in the stock Imiev pack. So I now had a full 2kwh 48v Calb battery that I didn't want to let sit for long periods at 100% SOC.
So I drained the pack back down to 50% SOC using the PIP powering a small 2.5kw (non inverter) style RC split system Aircon unit. It was cool at the time so I was using it in RC heat mode. It was a funny feeling sitting in a room with the thermostat set at 28C! bathed in warm...hot air. While a tiny battery and inverter where doing all the magic. I had to run it for several hrs to get the battery back down to roughly 50% SOC (Silly split system AC's and there high efficiency

.
It was interesting to see the live consumption reading on the PIP4048's display. 630w when the compressor was running and the Meter I was running it through showed 630.1w. I then increased the fan speed on the aircon unit and the PIP4048's display read 641w and the inline meter read 640w. It was nice to see them agree somewhat. I was also suprised at how low the consumption was on that particular inexpensive no name non inverter style AC unit . (I had always just assumed it's consumption was around 1kw) so that was a nice outcome.

It was a good test to see how the PIP4048 handles Air Conditioner spike loads as I was considering dedicating it (when it's not in Ejerrycan mode) to run several split system Aircon units at the same time. I will have to try it on one of my inverter style units and see if it has any funny issues with it (like it did a few times with the variable load of the Imiev charger)
