[RE-wrenches] Controller Adjustment?

[Jeffrey Yago]

How about a "training wheels" version of several popular charge controllers?
A simple toggle switch on the side that says "Extended Absence / Normal
Occupied" ?  
Then the installer can program two (2) sets of charge setpoints, one for a
normal get-as-much-as-you-can charging program, and a very low float-trickle
charging.

When we designed automation systems to control all the lighting and multiple
HVAC systems in large buildings we had a similar problem.  The first control
systems had extensive programming in a central desktop computer using custom
programming where the installer tried to guess what occupied and un-occupied
hours were needed in each office area and what occupied and unoccupied
temperatures the HVAC systems should be programmed to start and stop.  As
soon as people moved in to these new buildings most of this control
programming no longer matched reality and since nobody on site had access or
knew how to program the complex control systems they got disconnected or
over-ridden by people having no understanding as to how the HVAC should
operate.  

Finally the installers and manufacturers learned from their mistakes and
started installing wall mounted "non-adjustable" temperature sensors
(adjustable thermostats no longer used) which had a simple "reset" button on
the side.  Now if somebody is working late or needs a "kick" to their HVAC
system, they just press the button and a separate set of pre-programmed
setpoints go into effect for a given extended period of time. Employees are
happy as they can now get the HVAC systems to come back on if they happen to
have an un-scheduled Saturday morning conference room meeting, and the
owners are happy since the employees are not in a battle to see who can
over-ride the control systems to get the da-- air conditioner to turn back
on.

Just a thought........................
