Occasionally an unusual application might arise. For example: Exceptionally low room design temperatures or extraordinarily high coldrooms. Extreme and rare design conditions may be beyond the scope of the programs' inherent 'error trap' limits. They will inevitably call upon special knowledge and engineering skills in order to complete a totally successful design. As a safety measure Mistral therefore excludes various extreme inputs when programs are used in their 'default' setting. However, when an engineer is required to work on an unusual design a conscious decision may be made to enter 'Special Feature Codes' that will relax or even bypass certain of the programs' inherent 'dynamic error traps'. The procedure for accessing these 'Special Feature Codes' is described below and also appears under the 'Utils' folder of every Mistral program CD-ROM.
Program users are though warned to use these features with caution and are reminded that Mistral Associates cannot and will not accept liability for the consequences of any design produced using Mistral's intellectual property (software) whether or not the 'Special Feature Codes' were activated.

Descriptions of special program features that have been added will appear in the Features activated box.
To delete special program features (thus reverting the program to its standard operating mode) simply highlight the feature in the Features activated box and then click on Remove Feature.
Special Feature Codes:-
Program Code Feature
AIRWIND MZPP Relax door and window error trapping on grid (permits rooms to have no doors or windows).
AIRWIND CIWM Allow very high ambient (above 50ºC/122ºF)
COLDWIND MZPP Relax door and window error trapping on grid (permits rooms to have no doors or windows).
COLDWIND PATX Allow large room dimensions (above 100 metres/330’)
COLDWIND DEKK Allow ‘negative’ Product gains. Useful for 'tempering rooms' for example.
COLDWIND MIRF Allow room design temperatures down to -99ºC/-146ºF.
