Description
Specify professional-grade, brand-matched zoning control for Rheem® and Ruud® EcoNet® communicating HVAC systems with the iO HVAC Controls RM-XXXX Rectangular Zone Damper — a durable, precision-engineered motorized damper built to drop seamlessly into EcoNet zone panel installations. Designed for HVAC contractors handling new construction, zoning retrofits, and service replacements, the RM-XXXX eliminates compatibility headaches by delivering the exact 3-wire power-open / power-close control sequence that Rheem and Ruud EcoNet zone systems require — no adapters, no workarounds, no guesswork.
Constructed from rigid extruded aluminum, the RM-XXXX rectangular damper housing is built for long service life in demanding supply-duct applications. The aluminum body resists corrosion, holds tight dimensional tolerances for clean duct connections, and provides a sturdy platform for reliable actuator performance over years of zone cycling. Each damper ships equipped with a genuine Belimo® 24VAC actuator — the industry’s most trusted brand in HVAC damper actuation — delivering 18 lb-in of torque, 35-second stroke timing, and just 2.5 VA power draw for smooth, quiet, and energy-efficient operation.
One of the RM-XXXX’s standout contractor-friendly features is its dual motor mounting flexibility — the same damper can be ordered with either a side-mount or bottom-mount actuator, giving installers the option to fit the damper into tight joist bays, low-clearance mechanical rooms, or awkward retrofit spaces without compromising access or serviceability. This flexibility alone makes the RM-XXXX a go-to specification for retrofit jobs where existing ductwork and framing constrain motor orientation.
Available in standard sizes from 6″x6″ up to 36″x24″ — with custom sizes available on request — the RM-XXXX covers virtually every rectangular supply trunk and branch application in residential and light commercial zoning systems. A simple built-in minimum position adjustment lets technicians fine-tune bleed airflow for static pressure management, preventing short-cycling and protecting HVAC equipment in small or fully-closed zones. Backed by a 5-year warranty and available with same-day shipping from iO HVAC Controls’ Indianapolis, IN distribution center, the RM-XXXX is the professional installer’s choice for fast, reliable EcoNet-compatible zoning.
Features:
- Native Rheem® & Ruud® EcoNet® Compatibility — Engineered specifically for the 3-wire power-open / power-close control protocol used by Rheem and Ruud EcoNet communicating zone control systems — no adapters, no reprogramming, no protocol translation required.
- Genuine Belimo® Actuator — Every RM-XXXX ships with a factory-installed Belimo actuator, the industry’s gold standard for HVAC damper actuation — trusted for reliability, quiet operation, and long service life.
- Rugged Extruded Aluminum Construction — Lightweight yet strong rectangular housing resists corrosion, holds tight tolerances for clean duct connections, and provides a durable service platform for the life of the installation.
- Side-Mount or Bottom-Mount Motor Options — Unique dual-mount flexibility lets installers position the actuator on the side or bottom of the damper to fit tight joist bays, low-clearance mechanical rooms, and challenging retrofit spaces.
- Wide Size Range — 6″x6″ to 36″x24″ — Standard rectangular sizes cover virtually every residential and light commercial supply trunk and branch application; custom sizes available on request.
- 3-Wire Power-Open / Power-Close Control — Positive-drive bidirectional actuation ensures reliable, deterministic damper positioning in both directions — no spring-return failure modes to worry about.
- 24VAC / 2.5 VA Low-Voltage Operation — Minimal current draw supports multi-zone, multi-damper installations without transformer upgrades.
- 18 lb-in Actuator Torque — Strong torque output drives the damper blade smoothly against typical residential and light commercial static pressures.
- 35-Second Stroke Timing — Fast, controlled open/close cycles reduce HVAC system response lag while preventing ballistic slam that can damage blade seals.
- Built-In Minimum Position Adjustment — Field-adjustable bleed setting prevents equipment short-cycling, manages static pressure, and reduces duct noise in small or closed zones.
- Same-Day Shipping from U.S. Stock — Large inventory of standard sizes ships same-day from iO HVAC Controls’ Indianapolis warehouse — keeping contractor jobs on schedule.
- 5-Year Warranty — Professional-grade warranty coverage backs the RM-XXXX for long-term contractor and homeowner peace of mind.
Applications:
- Rheem® EcoNet® zoning systems — new construction, retrofit, and service replacement dampers
- Ruud® EcoNet® zoning systems — matched-brand zoning installations
- Multi-zone residential homes — 2-zone to multi-zone builds with rectangular supply trunk ductwork
- Light commercial zoning — small offices, retail suites, restaurants, and multi-use spaces on EcoNet platforms
- Service replacements — swapping failed OEM rectangular dampers without replacing the EcoNet zone panel
- Retrofit zoning upgrades — adding true zoning to existing Rheem/Ruud EcoNet-equipped homes
- Multi-story home comfort zoning — upstairs/downstairs or wing-based temperature separation
- Custom and luxury home builds — where Rheem or Ruud equipment is specified with integrated zoning
- Tight-clearance mechanical rooms — side-mount or bottom-mount actuator flexibility solves difficult install scenarios
