IMT550.com was designed specifically for organizations still relying on the Proliphix IMT Family. Instead of signing in to individual thermostats one by one, your team can work from one account-based portal with live dashboard visibility, scheduled overrides, recurring events, thermostat history, and role-based access.
Use the portal to reduce unnecessary HVAC runtime, tighten day-to-day control of occupied and unoccupied periods, and proactively monitor for conditions that may suggest heating or cooling equipment problems or inefficient system operation before they become bigger service calls.
Whether you manage one site or many, the portal is designed for teams that need a practical way to organize thermostat control, visibility, and accountability across multiple users and locations.
See thermostat status, current readings, operating state, override state, and location-based details without bouncing between individual thermostat web pages. The dashboard is built to keep your most important building information in one working view.
Create date and time based overrides, recurring events, and instant temporary changes so thermostats are not conditioning spaces longer than necessary. The goal is better control of occupied needs without wasting runtime after hours.
Use history, runtime behavior, and outdoor weather context to help identify unusual conditions that may point to heating or cooling equipment problems, comfort drift, or inefficient operation that deserves a closer look from operations or service staff.
IMT550.com stays focused on the thermostat family it was created to support. That means the workflow, vocabulary, and management tools are aligned to the realities of long-running IMT deployments rather than forcing your team into a broad, generic building platform.
For organizations still operating IMT Family thermostats, that focus matters. It reduces friction, shortens training time, and gives building teams a practical way to keep older smart thermostats organized, visible, and useful.
Includes free account setup assistance, thermostat onboarding help, and user-role definition support.
The service is designed to keep the onboarding path straightforward while still giving you the tools to manage thermostats with more discipline once they are online.
Before opening a new account or adding a thermostat, the portal tests the WAN IP, access port, and thermostat credentials to confirm a live connection is available.
Set up the main owner account, then add manager or viewer users so the right people can monitor, control, or simply review the thermostat portfolio.
Add thermostats to the dashboard, define locations, apply ZIP and time zone information, and build recurring event schedules or one-time overrides when needed.
Use the dashboard and history tools to review runtime, watch live status, make instant adjustments, and respond quickly when building conditions or operating schedules change.
The portal also offers a mobile-focused dashboard view for users who need quick access from a phone. It keeps the most useful live information close at hand without requiring the full desktop table layout.
The mobile view uses thermostat cards that make it easier to scan building, location, current comfort conditions, fan and HVAC status, and active override timing on smaller screens.
Users with the proper access level can launch a quick override directly from the mobile card, while all users can review the lighter mobile presentation of current readings and recent status.
Each mobile thermostat card also supports a 12-hour history view with a graph and raw data table, making it easier to review recent activity while in the field.
When needed, users can switch back to the full dashboard experience for broader table-based management, multi-thermostat workflows, and the full portal toolset.
Card-Based Monitoring
Review live temperature, humidity, state, setpoints, and override timing in a compact phone-friendly layout.
Instant Override Access
Open a fast override control from the card when an immediate temporary comfort change is needed.
12-Hour Mobile History
See a short graph and raw data table for recent thermostat activity without leaving the mobile view.
The portal is intended to supplement and organize thermostat operations, not just offer remote logins. Account-based management gives building teams a better way to assign responsibility, review actions, and work from a shared operational dashboard.
IMT550.com can also support custom-built functions for accounts that want a faster way to carry out repeated operational actions. Those custom tools can be designed for one thermostat, a group of thermostats, or a broader account workflow.
For example, an account may want a one-click action that restores occupied setpoints across selected thermostats during a weather event, special occupancy condition, or service situation. If a custom function is built for your account, it can be surfaced directly in the portal for faster use.
