Hire controls technicians

DDC installation or programming

Direct digital control, usually called DDC, appears in job titles covering several assignments. An installer may wire sensors, actuators, and controllers from approved drawings. A programmer may implement sequences and interfaces. A service technician needs to investigate the equipment and controls together.

Name the platforms, building types, and tasks in your opening. Explain who checks installation work and who handles the mechanical equipment, electrical supply, and network. If one person will cover several duties, state the level of independence required for each.

A room that will not reach its setpoint

Give the applicant a fictional complaint and some basic system information. Ask what they'd want to establish before making a change. Listen for questions about the actual condition, point identity, equipment behavior, schedule, and recent work.

Have them explain why each check matters and when they would involve the mechanical technician or controls lead. An immediate proposal to change a setting tells you less than a clear account of what's known.

Ask about a similar service call. What did they change personally, how was it approved, and what did the service note tell the next technician?

Point checks and current files

For installation, use a fictional point schedule with a mismatch to the field drawing. How would the applicant raise and resolve it? Ask how the final record stays consistent with the installed device and software.

For programming, discuss a sequence they delivered. Who agreed on the required behavior? What did they test, what files did they retain, and how did the operator learn what changed? Your company needs a usable project after the programmer leaves.

Controls engineers and site leads

A controls engineer's opening should identify design documents, sequences, integration work, and technical review responsibility. Ask for a permitted design example and have them explain a decision, a field revision, and its effect on the equipment. Verify the qualifications for the engineering work assigned.

A site superintendent needs a crew and coordination brief. Discuss work areas, drawings, materials, readiness for checks, and dependencies on the mechanical contractor. A project manager also needs responsibility for costs, schedule, customer decisions, and closeout. Use the low-voltage project-manager guide for that interview.

Platforms, service territory, and pay

Include platforms, installation or service mix, independent duties, training, supervisor, equipment support, territory, hours, on-call terms, pay range, benefits, tools, vehicle, and expenses.
