CAREL BOSS supervisor deployment

One supervisory system for the whole plant

BOSS is the CAREL supervisor — a local server for medium and large plants. It collects data from every controller on site, shows it on a single screen, archives trends and watches the alarms. You see the whole plant room from a browser: from the office or from your phone.

We do it turnkey: installation, device autodiscovery and configuration, enabling the plugins (integrations, MQTT, XML, Redfish), secure remote access over a private VPN, and graphical Maps that show the installation the way it really is.

What we deploy

A complete BOSS commissioning, or a single piece of it:

01

Installation & commissioning

BOSS installed on CAREL hardware (BOSS or BOSS mini), with network, users and permissions configured. A working system, ready to use.

02

Autodiscovery & device configuration

Automatic discovery and connection of controllers: Modbus (RTU/IP), BACnet, M-Bus, CAREL. Variables, alarms and parameters mapped for every device.

03

Plugins & integrations

MQTT to the cloud and IoT (including Azure IoT Hub), XML push/server, SNMP, BACnet, Redfish, the CAREL RED optimise cloud. We enable the ones you need.

04

Private VPN & 24/7 monitoring

We build private company VPNs — not only for BOSS. Encrypted remote access to the supervisor plus constant 24/7 monitoring: we react to alarms before they grow into a failure.

05

Maps & synoptics

Graphical pages (2D/3D) built right in the browser with the Map editor: chillers, circuits and sensors live. No external software.

06

No-code rules & schedules

A code-free rules engine (bCore 2.0): control logic, alarms and events in one place. System calendar, defrost scheduler and an energy plugin.

07

Alarms, trends, reports

Archived measurements, trend charts, alarm history with notifications (email/SMS) and scheduled reports.

08

Cybersecurity & maintenance

Role-based access control (RBAC), Secure Boot, automatic backups and updates, signed packages. Configured to CAREL's security best practices.

Live Maps

This is a BOSS synoptic of a chiller with two circuits — circuits, parameters and states live, ready for the operator.

Protocols & plugins

BOSS integrates devices and upper-level systems through a set of plugins — we enable the ones you need:

Modbus RTU/TCP, BACnet, M-Bus, CAREL — with field-device autodiscovery.
MQTT — data to the cloud and IoT platforms (including Azure IoT Hub).
XML push / XML server — data exchange with upper-level systems (BMS, ERP, reporting).
SNMP — integration with IT monitoring.
Redfish — hardware supervision over a standard API; we documented the full setup in the Knowledge Base.
RED optimise — the CAREL cloud for remote fleet management of supervisors.

Why iceLAB

We know CAREL hardware and software. We program CAREL controllers and deploy their supervisors — BOSS is our daily work, not a first attempt on your site.
IT/OT integration under one roof. Networks, VPN, protocols and data — one team from the controller to the cloud, no hand-offs between vendors.
Secure remote access. A private VPN instead of exposing the supervisor to the internet. Remote service without opening a security hole.
We run 24/7 monitoring. We supervise plants in the field every day, so we know how to configure BOSS to actually help rather than bury you in alarms.

Frequently asked questions

What is BOSS?

BOSS is the CAREL supervisor — software for monitoring refrigeration and HVAC plants. It collects data from controllers, shows it on Maps, archives trends and manages alarms, all from a web browser.

Does BOSS integrate third-party devices?

Yes — over Modbus (RTU/TCP), BACnet and M-Bus, with autodiscovery. It forwards data through MQTT, XML push or SNMP to the cloud and upper-level systems.

Does BOSS expose data over Redfish?

Yes — BOSS has a Redfish Server plugin, so the hardware can be supervised over the standard Redfish API. We documented the full step-by-step setup in the Knowledge Base.

How does remote access to BOSS work?

We set up a private VPN, so access to the supervisor is encrypted and doesn't require exposing it to the public internet. We also build private VPNs for a company's whole infrastructure, not just BOSS.

What does BOSS run on?

On dedicated CAREL hardware: BOSS mini (up to ~50 devices) or BOSS (up to ~300 devices) — we pick the variant to match the size of the plant.
