NTI INSTALLATION MANUALS
Part 4 - Water Piping
K. Floor Drying Function The Floor Drying Function is a special function that allows the installer, through a dedicated heating cycle, to use the boiler for drying a freshly poured radiant oor during a oor system installation. The installer can set parameter 2.7.4 (Floor Drying Cycle) and choose the cycle‘s operation (Functional Heating, Curing Heating, a combination of Functional and Curing Heating, or Manual Heating). This function can follow di erent ow temperature pro les according to the parameter 2.7.4 values:

Functional Heating: The supply setpoint temperature is kept at 77°F for three (3) days, then increased to the target temperature (parameter 2.7.5 - default = 131°F) and kept at this temperature for four (4) days.

Curing Heating: Supply setpoint temperature increases from 77°F to the target temperature (de ned by parameter 2.7.5) by 5F/day, stays at target temperature for “x” days, and decreases from target temperature to 77°F by 5°F/day for a xed total amount of days to 18. Example 1: Parameter 2.7.5 = 131°F; increasing phase from 77°F to 131°F = 6 days; stays at 131°F for 6 days; decreasing phase from 131°F to 77°F = 6 days. Example 2: Parameter 2.7.5 = 140°F; increasing phase from 77°F to 140°F = 7 days; stays at 140°F for 4 days; decreasing phase from 140°F to 77°F = 7 days.
