See Figure 11 for the location of the cover. The factory setting is 0 (OFF).
Technical Instructions OpenAir® Non-Spring Return Rotary Electric Damper Actuator 24 Vac – Modulating Control Document Number 155-187P25 May 13, 2021 The type of actuator required depends on several factors. Sizing 1. Obtain damper torque ratings (ft-lb/ft2 or Nm/m2) from the damper manufacturer. 2. Determine the area of the damper. 3.
OpenAir® Non-Spring Return Rotary Electric Damper Actuator 24 Vac – Modulating Control Manual Override Technical Instructions Document Number 155-187P25 May 13, 2021 To move the damper blades and lock the position with no power present: 1. Slide the red manual override knob toward the back of the actuator. 2. Make adjustments to the damper position. 3. Slide the red manual override knob toward the front of the actuator. Once power is restored, the actuator returns to automated control. Figure 22.
Technical Instructions OpenAir® Non-Spring Return Rotary Electric Damper Actuator 24 Vac – Modulating Control Document Number 155-187P25 May 13, 2021 Wiring • All wiring must conform to NEC and local codes and regulations. • Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers. • The sum of the VA ratings of all actuators and all other components powered by one transformer must not exceed the rating of the transformer.
