Complete newbie here, need explanation of terms/abbrevs

[temcat]

Hi all,

I'm new to the forum and to control systems. Despite the latter, currently I'm tasked with localization of a certain control software and therefore need explanation of some terms and abbreviations I encounter in the SW strings.

Could you help me by giving some short explanations? Sorry for the possible stupidity of the questions and thank you in advance!

1) "Load Rolling": this reduces overall energy consumption by "shedding" continuously unnecessary loads.
a) What does it mean to "shed" a load? Can you suggest me some synonyms to make the term clearer?
b) Why "rolling"?

2) "Box mode", "Box Htg", "Suppl Htg" - ?
"Htg" is heating, this I can figure out.
"Suppl" must be "supply" or "supplemental" - which one is it?
"Box Htg" & "Suppl Htg" seem to be smth like 2 modes of heating - what do they mean?

What language are you tasked with localizing these terms to? A dictionary of engineering terms might suffice.

The reason may be to reduce peak demand either because of an agreement with the utility (demand response), or simply because there's not enough power on the grid. Think of a rolling blackout.

correct.

"Suppl" must be "supply" or "supplemental" - which one is it?

Supply.

The mode depends on the VAV Box Control manufacturer. Here are possible modes for a Honeywell VAV box:
Heat, Cool, Reheat, MornWarm, NightPurge, Pressurize, Depressurize, Trackflow, ManualPos, ManualFlow, FrzProtect, FactoryTest, IoTest, FLoatOutSync, Disabled, Manual.

"Box Htg" & "Suppl Htg" seem to be smth like 2 modes of heating - what do they mean?

A box may or may not know the supply/inlet temperature, and a discharge temp. The difference being temperature of the air being supplied to a box, and temperature of air leaving a box.

If you post the brand name of the control system you're working with, you're more likely to get someone here to help out.

"Shed a load" is to turn a piece of equipment off for a period of time to reduce energy.

I'm doing Russian localization. I do have access to engineering dictionaries, they just don't contain all the terms.

Thank you! Somehow managed to miss this when Googling. The "rolling blackout" reference was helpful.

Thanks, it all has become clearer now.

It's Johnsons Control.
