C. APPENDIX C. ERROR MESSAGES

In this appendix have been described all error, warning and hint messages appearing in Instal-heat&energy program. Messages have been divided into groups concerning individual project positions.

Errors, which can appear for each numerical field in project, after entering an incorrect value:

Error: ...Non-defined expression

This message is displayed, when not any value has been declared in numerical fields of edited data. Special cases:

- partition, see Reference marks – Error messages, Reference – Error “Not defined expression”

Error: Floating point excess

This message appears after exceeding the value of number, which is not operated by the computer. Such situation is occurring very rare.

Error: Unknown identifier

This message is displayed during entering in edition fields of such expression, which is neither properly declared, nor it is a function.

Error: Invalid unit operation

A message displayed during entering in edition fields of mathematical operations having various types of units.

Error...Result out of range – too low

This error appears, when in numerical fields will be entered values from beyond the lower limit.

Special cases:

- for general data, see Reference: Error “Value too small”

- for partitions, see Reference: Error “Value too small”

- for compartments, see Reference: Error “Value too small”

- for storeys, see Reference: Error “Value too small”

- for thermal zones, see Reference: Error “Value too small”

Error… Result out of range – too high

This error appears, when the value from beyond the upper limit will be entered.

Special cases:

- for general data, see Reference: Error: Value to big

- for partitions, see Reference: Error: Value to big

- for compartments, see Reference: Error: Value to big

- for storeys, see Reference: Error: Value to big

- for thermal zones, see Reference: Error: Value to big

Error: Incompatible unit

This message concerns entering in data edition field of expression, the unit of which is not compatible with required one, assigned to specified edition field.

Error: Error in variable

This message appears after using of not properly defined variable in data edition field. Go to variable editor to delete the incorrect declaration.

Error: Expression calculation error

This message concerns a situation, when in expressions entered in edition fields any incorrect mathematical operations will be entered.

Error: Error in expression

This message is displayed during entering of incorrect expression syntax.

Hint: ...(Determining of value impossible)

This message appears as a secondary message, concerning non-determining of building parameters value because of not completed or incorrectly completed data, according to which the building parameters are determined.

Special cases:

- for general data, see Reference: Hint “Determining of value impossible”

- for partitions, see Reference: Hint “Determining of value impossible”

- for compartments, see Reference: Hint “Determining of value impossible”

- for storeys, see Reference: Hint “Determining of value impossible”

- for thermal zones, see Reference: Hint “Determining of value impossible”

Hint: ...(Value too small)

This message appears as a secondary message, concerning the value calculated on the basis of data given before. It is displayed, when the result value determined according to basic data is under the lower limit or after their incorrect completion or in case of missing value declaration.

Hint: ...(Value too big)

- This message appears as a secondary message, concerning the value calculated on the basis of data given before. It is displayed, when the result value determined according to basic data is over the upper limit.

Warning: ...(Value too small)

Message informing about probability of too small value of a building parameter.

Special cases:

- for partitions, see Reference: Warning “Value too small”
