Read the building from outside the station.

D3 Virtual Operator helps building engineers and operators understand alarms, trends, and how the automation system works. It reads a Niagara-based system from the outside. It does not sit in the station, and it does not command it.

The station stays in charge.

Niagara-first. D3 Virtual Operator works with Niagara-based systems, including Honeywell WEBs, Distech, JCI FX, and Siemens Talon.

  1. The supervisor stays in charge

    Graphics, schedules, alarms, and histories remain on the system that already runs the building.

  2. A read-only assistant

    Virtual Operator reads from outside the station. It does not write setpoints, schedules, or priority arrays.

  3. Engineers and operators

    Plain language about an alarm, a trend, and how that part of the system is supposed to work.

The station remains the system of record. The assistant sits outside it.

The assistant explains the system. The operator still runs it.

Data centers first. The same read travels.

The first sites are data centers, where a missed alarm is expensive and the staff already live in the graphics. The same outside read helps schools, universities, owners with more than one site, and hotels whose chief engineer is covering a mixed plant.

  • Data centers
  • Schools
  • Universities
  • Multi-site owners
  • Hospitality

Four ways to hire the same practice.

D3 Virtual Operator

Read-only help with alarms, trends, and how the system is arranged. Health Check through a Critical tier for data halls.

DDC programming

Sequences, point lists, schematics, graphics, and controller logic. Works with Niagara, Distech Controls, and Honeywell WEBs.

D3 PointScope

Points lists, device counts, sequences, scope flags, and pre-bid questions from the drawings and the specification. Not a price.

D3 Controls Visual Troubleshooting Guides

Operator Edition for $19, and the Technician Manual for $49. A sampler of three maps is free.

CRAH supply airMap VO-M-076. A high supply-air temperature on a computer-room air handler, and the checks an operator makes before anyone changes a setpoint.

This clip walks map VO-M-076: a high supply-air temperature on a computer-room air handler, and the checks an operator makes before anyone changes a setpoint. Two more maps play on the store page. Sound stays off until you turn it on.

The free sampler is a zip of three operator maps: a pump or fan that will not start, alarm triage, and data-hall humidity and dew point. The pump-or-fan map also includes its technician pages.

Published ranges. The charge is set in Stripe.

A Payment Link is created for the agreed amount. Nothing in the browser can change it. Full scope for each tier is on the Virtual Operator page.

Health Check

$1,950

A bounded read of one station: alarm history, a selected set of trends, and a written note on how those systems are arranged.

Monitor

$495/mo

Scheduled written reviews of alarms and trends for an agreed point set. This is a review on a cadence you agree to, not an unattended watch.

Virtual Operator

$1,250–$1,950/mo

Plain-language help for the engineers and operators on a staffed site: what an alarm is tied to, what a trend has been doing, and how that part of the system is supposed to work.

Critical

$1,950–$2,950/mo

The same read-only assistant for sites where a missed alarm is expensive, with a tighter review schedule and a named response path during the hours the agreement covers.

Thirty years on the station, written down.

D3 CNTRLS LLC has spent more than 30 years programming and troubleshooting building automation: sequences, graphics, retrofits, and the long handoff to the operator who inherited someone else’s logic.

The office is in Huntley, Illinois. Virtual Operator, PointScope, the programming work, and the field guides all come from that practice.

Tell us which station, or which bid set.

A Health Check, a programming scope, or a controls takeoff all start the same way: a note to D3 CNTRLS about the building and the documents.
