Built for franchise operators • Plug-and-play • Measurable

Reduce rooftop HVAC energy waste without replacing equipment.

The RTU-X Optimization Module is a non-invasive external optimization add-on designed to improve runtime efficiency and provide real-world proof of savings—with a disciplined pilot process that makes rollout repeatable.

✔ Non-invasive 24V intercept
✔ Fail-safe OEM default
✔ CT-based measurement
What owners care about
Simple math. Low risk. No disruption.
Fast integration
Designed for < 2 hours typical integration (site dependent).
Fail-safe
On loss of power, the system returns to OEM pass-through.
Measurable
CT-based monitoring and runtime logging support credible M&V.
Scalable
Standardized wiring + SOPs for repeatable installs.
Pilot-first rollout
We validate performance and installation repeatability, then scale across your portfolio.

How RTU-X works

A warranty-conscious, upstream optimization layer designed to preserve OEM safety behavior while reducing waste from inefficient cycling and unnecessary runtime.

🧠

Upstream control intercept

Intercepts standard 24V control calls (e.g., Y1) and applies timing logic (minimum runtime + anti-short-cycle).

🛡

Fail-safe OEM default

Normally-closed relay path is designed so loss of power returns the unit to factory behavior (OEM pass-through).

📈

Proof of savings

Non-invasive CT monitoring and runtime logging support measurement and verification during pilots and rollout.

ROI calculator

Use conservative inputs. For pilots, we validate with baseline + post-install measurement.

Owners trust simple math
Savings = HVAC spend × improvement %. ROI = investment ÷ annual savings.
  • Best fit: high runtime sites, higher energy rates, demand charge markets
  • We underwrite conservatively and prove results with measurement
  • Optional financing/shared-savings models can reduce upfront friction

Warranty-conscious, non-invasive architecture

RTU-X is designed to avoid common warranty-void triggers by staying upstream, preserving safeties, and failing back to OEM behavior.

Designed to preserve OEM behavior
Optimization upstream—factory safeties remain intact.
  • No refrigerant system modification
  • No OEM control board replacement
  • No bypass of high/low pressure safeties
  • Fail-safe OEM pass-through on loss of power
Red lines we do not cross
These are the actions that commonly create warranty risk.
  • No tapping into sealed refrigerant lines
  • No disabling safeties or limit switches
  • No compressor shell modifications
  • No operating outside OEM rated parameters
Warranty policies vary by OEM; our architecture is designed to operate within OEM specifications.

Disciplined pilot process

We don’t “guess.” We validate, document, then scale.

FAQ
Quick answers to common questions.
Will this void my RTU warranty?

RTU-X is designed to avoid common warranty-void triggers: it does not modify refrigerant systems, bypass factory safeties, or replace OEM boards. Warranty policies vary by manufacturer; installs are documented and designed to operate within OEM specifications.

How long does installation take?

Typical integration is designed for under two hours per unit (site dependent). The pilot phase validates repeatability and documents best practices.

What savings should I expect?

Results depend on runtime, unit condition, controls, and climate. We use conservative assumptions and verify with baseline + post-install measurement during pilots.

What happens after I submit?

We confirm basic site details, propose a pilot plan, and schedule installation + measurement. If the pilot performs as expected, we build a rollout plan for your portfolio.
