Total slab drying time
:
–
The minimum total duration (3) is
automatically calculated by the heating
controls. This is based on a rise of supply
temperature of a maximum 18 °F (10 °C)
per day.
–
A higher value must be entered for the
whole duration (3) if the slab cannot bear
this increase. This produces a
corresponding reduction in the daily
increase.
–
The first stage and the last stage of the
supply temperature is 78 °F (25 °C) (fixed
value).
Example:
Maximum supply temperature (1) =
122 °F (50 °C)
Duration of maximum supply temperature (2) =
7 days
Max. increase/decrease in temperature
per day = 9 °F (5 °C)
Total duration of slab drying (3) = 17 days
