An “obsolete” BMS: do you really have to replace it all?

Your building is less than 15 years old. Yet a quote worth several hundred thousand euros lands on the table to replace every LON controller. Before you invest, check what is genuinely necessary.

Independent advice: Foobot does not sell controllers.

The problem

A fair doubt: do you really have to replace everything?

On many sites under 15 years old, the same scenario plays out.

A maintenance engineer announces that the controllers are no longer supported, standing in front of a BMS cabinet.01
“Your controllers are obsolete. Sorry.”
The announcement

declared by the BMS maintenance provider itself.

A salesperson presents a 450,000 euro quote for a full replacement.02
“Everything has to go.”
The quote

same person, a few days later.

A lone decision-maker, puzzled, facing the decision.03
The deadlock

No one in-house to challenge it on technical grounds.

A real diagnosis… or a sales pitch?

After the second opinion

A dissenting opinion is not always enough.
You need proof from the field.

To settle it, we do not ask you to take our word for it. We test it on your own installation.

Our approach

Testing and documenting the replacement under real conditions.

01
Technical diagnosis

Software and hardware obsolescence (controllers, supervision, network), the real dependencies between equipment, the genuinely critical points.

02
Operational test
Unique on the market
Decommissioning and replacing one controller under live operating conditions
Consulting third-party BMS integrators: cost, lead time, complexity
The field proof no one else carries out.
The test answers your questions and documents a process
Deliverable
01
The real cost

What the operation actually costs, backed by quotes from third-party integrators.

02
The real timeline

How long it takes, including the interruption to operations.

03
The best plan for your controllers

One by one, floor by floor or zone by zone: the safest path for your site.

Better decisions

You are no longer choosing between two opinions.

Full replacement or phased migration? You decide from a replacement that has actually been carried out.
