![]() Occasionally the instability is a result of over complicated or flawed geometry. MacroFlo openings that are too large (eg 50 openable area). Reduce time step (From 10 minutes to 6 minutes, then 2 minutes etc.) 1. How do I prevent this - Space temperature controls based upon sensed variable with a high radiant fraction. Adding a small amount of thermal mass to the construction by increasing the density of a layer usually overcomes the problem. How do I prevent this ApacheSim reports an instability. These can give rise to a 'surface instability'. Extremely lightweight structures - eg large areas of walls or roof made entirely of glass. We recommend using the default setting (control based on air temperature).Ĥ. Setting the Control Temperature Radiant Fraction (Apache View -> Settings -> Building) to a value greater than 0. MacroFlo openings that are too large (eg 50% openable area).ģ. Instability problems are most commonly caused by:ġ. Reduce time step (From 10 minutes to 6 minutes, then 2 minutes etc.) You can force sign out from any device at Revizto Workspace. To fix the problem, sign out of excess devices. You can sign in to Revizto application on up to 5 devices. Space temperature controls based upon sensed variable with a high radiant fraction.Īs you know the error message provides the reasons/ remedies for the issue - This error appears on the login screen of Revizto application version 5.7 or earlier when you are signed in to Revizto application on 5 devices simultaneously. Very small or non-existent temperature control deadbands Numerous, complex, or substantial MacroFlo openings and associated controls Internal gains or HVAC terminal units with a high radiant fraction A thermal zone or surface element thereof that, a result of highly conductive materials, is subject to extreme thermal losses or gains A thermal zone or surface element thereof that is subject to very high solar gains A thermal zone with insufficient space conditioning relative to the rate of heat gain or loss in that space Revizto is the industry-leading Integrated Collaboration Platform (ICP) used by Architects, Engineers, Contractors and Owners to maximize workflows. A conditioned thermal zone with one very small dimension, relative to its other dimensions (e.g., a chilled or heated floor slab) A very, very small thermal zone (relative to the connected mechanical system capacity and/or internal/external thermal loads) Surface Temperature instability shows up when you have one of just a few situations:
