Maintenance:
No routine maintenance is required. Each component’s design and material selection assures dependable long-term reliability and
performance. Careful installation will also enhance long term reliability and performance.
CSP-5002 DAMPER CONTROLLER/ACTUATOR
All Nailor standard right hand (and optional left hand) terminal units have a 1/2" (13), diameter drive shaft and a clockwise to close damper
rotation (Dual Duct Left Hand Deck CCW to close). Full damper shaft rotation is 45 or 90 degrees depending on model. The CSP-5002
should be mounted on the damper drive shaft so the actuator will stall at either end of the stroke to ensure tight shut-offs and full rotation.
Ensure the two jumpers are set for the correct damper rotation.
The CSP-5002 has a tri-color LED that indicates the current action of the damper: RED – Closing, GREEN – Opening, WHITE – Satisfied.
The CSP-5002 provides pressure independent VAV control for terminal unit primary valves. Primary air volume is monitored by the use of a
multi-point flow sensor located in the inlet duct. Differential pressure is measured by an onboard platinum transducer. The changes in the
inlet static pressure will vary the position of the inlet damper. Flow limit adjustments are made using a digital DC voltmeter at the thermostat.
The CSP-5002 is factory calibrated with VNOM adjustment centered for the enclosed voltage - airflow charts. Do not
adjust. Dampers are
always shipped in the full open position.

POWER REQUIREMENTS:
Controller / actuator / thermostat is 7VA plus any output loads for fan relays, heating contactors and control valves (assume 10 VA each).
Always switch control voltage off prior to disconnecting any wires from the controller.
