D3 Virtual Operator

An assistant that reads the station and does not command it.

Virtual Operator helps building engineers and operators understand alarms, trends, and how the system works. The connection is read-only and it stays outside the station. Niagara-first. D3 Virtual Operator works with Niagara-based systems, including Honeywell WEBs, Distech, JCI FX, and Siemens Talon.

Architecture

Outside the station, on purpose.

The supervisor already runs the building. Virtual Operator does not replace it, does not live inside it, and does not take a write path back to it.

  1. 01 · Station

    The supervisor stays in charge

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

  2. 02 · Outside

    A read-only assistant

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

  3. 03 · People

    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.

What it is for

Three questions operators already ask.

  • What is this alarm tied to?
  • What has this stored trend been doing?
  • How is this air handler, terminal, or plant supposed to work?

The answer names the equipment, the point, the sequence step, and the shape of the history that is already stored. It does not change a setpoint.

Illustrative exchange, not a live session

Operator. AHU-2 supply temperature is in alarm. What should I look at before I touch the setpoint?

Assistant. The alarm is on the supply-air temperature point. The stored trend shows the temperature climbing after the cooling-valve command fell. The sequence calls for that valve to open as supply temperature rises above setpoint. Compare the valve-command trend with the temperature trend before anyone edits the setpoint.

Beside the graphics

The graphic shows the point. The assistant explains it.

Limits

What it will not do.

  • It will not write setpoints, schedules, or priority arrays.
  • It will not replace the operator or the engineer.
  • It will not program a controller or produce a new sequence of operation.
  • It will not commission equipment. Functional testing is a separate, human service.

If the station needs new logic, graphics, or drawings, that work is DDC programming. The technician manual for this product is in the store.

Where it fits

Data centers first.

Data halls are the first market: a small staff, a loud alarm list, and a high cost when the wrong point is chased. The same read is used for schools, universities, multi-site owners, and hospitality, where one engineer often covers more than one plant.

Coverage hours, when a tier includes them, are whatever the agreement writes down.

Pricing

Four tiers. One read-only rule.

Health Check and Monitor have a single published price. Virtual Operator and Critical are scoped inside a published range once the point count, the sites, and the review schedule are known. The Payment Link charges the agreed amount.

One station

Health Check

$1,950

One-time.

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

  • Read from outside the station
  • Alarm history for an agreed window
  • A selected set of stored trends
  • A written explanation an operator can use on the next service call

Scheduled notes

Monitor

$495/mo

Billed monthly at this amount.

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.

  • An agreed point set
  • Written notes for the building engineer
  • Review cadence written into the agreement
  • Read-only connection from outside the station

Staffed sites

Virtual Operator

$1,250–$1,950/mo

Agreed inside this range.

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.

  • Alarm, trend, and sequence explanations
  • Written for the people who already run the building
  • No writes to the station
  • Monthly amount set inside the published range once the point count is known

Data centers

Critical

$1,950–$2,950/mo

Agreed inside this range.

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.

  • Scoped for data halls and similar plants
  • Tighter review schedule, written into the agreement
  • Named response path during the covered hours
  • Monthly amount set inside the published range

Questions

Before you send a station.

Does Virtual Operator write to the station?

No. It reads alarms, histories, and point data from outside the station. Setpoints, schedules, and priority arrays stay with the people who already operate the system.

Does it replace the building operator?

No. It explains what the system is doing so an engineer or operator can decide. The station and the staff remain in charge.

Which systems does it work with?

It is Niagara-first. It works with Niagara-based systems, including Honeywell WEBs, Distech, JCI FX, and Siemens Talon.

Is the connection inside the supervisor?

No. The assistant stays outside the station. The supervisor continues to run the building.

What does the monthly range mean?

Monitor is $495/mo. Virtual Operator is scoped at $1,250–$1,950/mo. Critical is scoped at $1,950–$2,950/mo. A payment link is created for the agreed amount, so the figure is not something a browser can edit.

Does a Health Check turn into a subscription?

No. Health Check is a one-time $1,950 review of one station. A monthly tier is a separate agreement.

Start with the station you already have.

Name the supervisor, the site type, and whether you want a one-time Health Check or a monthly read. Ask D3 for the published tier. Buying a tier is a follow-up email, because those checkout links are not on the site yet.
