Subject: Turning on New Automatic De-humidification Mode
Background: Some cell sites can have higher indoor humidity due to their lower heat load. In these sites, the compressor does not run long enough for dehumidification and the computer equipment does not generate enough heat to control the relative humidity. In these sites, automatic de-humidification mode can be turned on to control the higher humidity for these sites.
Note: software version 13B81 or above required. Contact us at HVACsupport@tempesttelecom.com for information regarding software upgrade.
Note 2: De-humidification mode is not as energy efficient and should only be enabled for sites experiencing excessive humidity.
