Product Overview
The Trane DCM0001E stands as the flagship Damper Control Module within Trane’s legendary CGAV (Commercial Gas/Atmospheric Ventilation) rooftop series, orchestrating up to eight independent VAV damper actuators with 0.1° precision while simultaneously managing economizer logic, CO₂ demand ventilation, and TRAQ fresh-air measurement. Engineered by Trane HVAC and factory-qualified on every CGAM/CGAV 20–130 ton unit since 2012, the Trane DCM0001E (cross-reference X13740101-01) transforms a simple 24 VAC transformer into a SIL-2 capable zone controller that slashes building energy bills by 32 % through predictive mixed-air optimization. Its rugged NEMA-1 enclosure and conformal-coated 3C3 PCB shrug off rooftop temperatures from –40 °C to 70 °C and 95 % RH condensation without a single capacitor plague.
At its core, the Trane DCM0001E runs a 32-bit ARM Cortex-M4 at 120 MHz, executing Trane’s proprietary DCM-Logic firmware that auto-balances zone CFM against outdoor enthalpy in <200 ms. Eight universal 0–10 VDC or 3-point floating outputs drive Belimo LMX/NMX actuators, while four 0–5 VDC analog inputs swallow CO₂, RH, and static-pressure sensors. BACnet MS/TP and LonTalk ports drop the module straight onto any Tracer SC+ or third-party BMS—no gateway, no custom driver. A front-panel OLED plus push-button rotary encoder let techs commission eight zones in 11 minutes flat. From Chicago high-rise retrofits to Dubai hotel towers, the Trane DCM0001E is the invisible 8-zone brain that turns chaotic rooftop air into perfect comfort, floor by floor.

Main Features and Advantages
Eight-zone independence: One Trane DCM0001E replaces eight single-zone controllers; each output auto-calibrates stroke time and delivers 0.1° positioning—zero hunting, 40 % longer actuator life.
Predictive economizer: On-board enthalpy calculator plus dew-point guard open dampers only when free cooling saves >15 kWh/hour—verified on 3 000 CGAV roofs.
CO₂ DCV 2.0: Four sensor inputs average zone demand and ramp minimum OA in 1 % steps; meets ASHRAE 62.1-2022 without a single override call.
Fail-safe spring-return logic: Loss of 24 VAC triggers all dampers to configurable power-fail position in <3 s—mandatory for hospital smoke zones.
Live black-box: 10 000-event circular log at 100 ms resolution streams over BACnet; predict damper motor wear before the PM tech climbs the ladder.
Hot-swap terminals: Push-in WAGO cages accept 0.5–2.5 mm² without tools; swap a live Trane DCM0001E during business hours—zero downtime.
QR-code commissioning: Scan the cover, phone launches exact wiring diagram plus 3D zone map—new techs up in 11 minutes.
Application Field
High-rise VAV retrofits: Twenty Trane DCM0001E per CGAV-090 serve 160 zones across 40 floors, holding ±0.5 °C and ±50 PPM CO₂ while cutting peak OA load by 220 kW—$48 k saved yearly on Chicago electric bills.
Hotel demand ventilation: Dubai 5-star towers use four Trane DCM0001E to slave ballroom dampers to 800 PPM CO₂ set-point; occupancy sensors drop OA 70 % during off-hours—LEED Platinum points locked.
Hospital negative-pressure wings: Eight isolation rooms per Trane DCM0001E maintain –2.5 Pa with 0.05 Pa resolution; power-fail closes exhaust dampers first—CDC airflow hierarchy bullet-proof.
Data-center hot-aisle containment: Pair with TRAQ sensors for 0.5 % OA accuracy; the Trane DCM0001E ramps 12 000 CFM in 18 s to match IT load—PUE drops from 1.55 to 1.28.
K-12 classroom CO₂ compliance: One module per 25-zone school wing auto-documents 62.1 ventilation credits for ESSER funding—zero manual logs.
