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.
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.
- 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.
- 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
- No tapping into sealed refrigerant lines
- No disabling safeties or limit switches
- No compressor shell modifications
- No operating outside OEM rated parameters
Disciplined pilot process
We don’t “guess.” We validate, document, then scale.

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.
