ICM Controls ICM708 - GE 2.3 ECM Motor Speed Controller (PWM, 18–30 VAC)
ICM Controls ICM708 - GE 2.3 ECM Motor Speed Controller (PWM, 18–30 VAC)
The ICM-ICM708 is a dedicated controller for GE 2.3 ECM blower motors, delivering precise airflow/CFM control via an onboard potentiometer that adjusts the flow-index from 0–100%. It provides LED RPM feedback and drives the motor with a 14 VDC, 80 Hz PWM signal; power input is 18–30 VAC. Made in USA.
Key Features
- Designed specifically for GE 2.3 ECM motors (not for PSC/X13).
- 0–100% flow-index adjustment using the front-panel dial for quick commissioning and balancing.
- LED RPM/flow display for live diagnostics and setup verification.
- PWM output: 14 VDC at 80 Hz; RPM input: 5 VDC.
- Supply voltage: 18–30 VAC (typ. 24 VAC).
- Replaces: EVO/ECM-VCU-36-mp.
- Made in USA.

A: No. The ICM708 is engineered for GE 2.3 ECM motors only.Q: What power does it need?
A: 18–30 VAC (typical 24 VAC). The RPM feedback is 5 VDC, and the PWM drive is 14 VDC at 80 Hz.Q: Can it help with air balance?
A: Yes—its 0–100% flow-index adjustment and RPM display make it ideal for fine-tuning airflow during commissioning and service.
