What to do if there's no air flow at the ALERTON MICROSET 4 Accessories sensor?
If there is no air flow at the ALERTON Accessories sensor, it may be due to blockages on the wall around the sensor. Remove any obstructions or relocate the Microset 4 to a clear location. Also, engineering should review mechanical design drawings for sensor and diffuser placements.
Why does solar exposure heat the ALERTON MICROSET 4 sensor?
Solar exposure heats the ALERTON Accessories sensor because the Microset 4 is mounted near a window or glass door, placing it in direct sunlight for a portion of the day. To resolve this, physically move the Microset 4 to avoid direct sunlight. Engineering should also review mechanical design drawings for sensor and diffuser locations and avoid installing on external walls.
What to do if air flow across wall surface is too high for ALERTON MICROSET 4?
If the air flow across the wall surface is too high, it may be due to improperly designed or aimed diffusers causing down drafts along the walls. Engineering should review mechanical design drawings for sensor and diffuser locations. Adjust the diffusers, ensuring air is not directed toward the Microset 4.
How to stop air infiltration through ALERTON Accessories Microset 4?
Air infiltration through the ALERTON Accessories Microset 4 can occur when air flows into or out from the wall cavity, penetrating through the backplate. This is often due to pressure differences in controlled spaces, such as the stack effect in high-rise buildings. To prevent this: * Affix a closed-cell foam barrier between the Microset 4 backplate and the wall, using sealant, and/or putty. Completely cover the wiring opening and all backplate screw holes. * Add insulation into the wall cavity when mounting the Microset 4.
What to do if temperature difference between wall cavity and space impacts ALERTON Accessories?
If the temperature difference between the wall cavity and the space temperature impacts ALERTON Accessories, it can contribute to air infiltration and affect the wall's surface temperature. To mitigate this: * Affix a closed-cell foam barrier between the Microset 4 backplate and the wall, using sealant, and/or putty. Completely cover all backplate screw holes. * Add insulation into the wall cavity when mounting the Microset 4. * Do not install on external walls.
