Description
The Johnson Controls TDR66A-4000 is an electronic fan speed control designed for use within P66 series applications. It modulates fan motor speed electronically, giving installed HVAC equipment graduated airflow control instead of fixed-speed operation. The control accepts either 240VAC or 120VAC supply, fitting common single-phase line voltages found in the field.
Current handling spans 8A at 240VAC and 16A at 120VAC, matching the dual-voltage rating to typical fan motor loads. Wiring terminals require copper conductors only, as marked on the unit. Manufactured by Johnson Controls and assembled in Mexico, the control ships ready for field connection.
Frequently Asked Questions
