Table 1
Note: the dew point, highlighted in the table, refers to the
environmental conditions considered excellent in the summer:
Dew point = 16.3°C, with room temperature at 26.0°C and
room humidity equal to 55.0%RH.
ATTENTION
- Condensate will form on the surfaces with temperature lower
than or equal to that of the dew point calculated C-dP.
- The dew point is calculated automatically by the equipment when
environmental conditions change.
For all details see ‘ ‘ C-dP ’ DEW POINT MANAGEMENT ‘.
Safety Control Algorithm
The ‘ Safety Control ‘ algorithm is used to manage the two relays
controlling the thermostat and the programmable thermo-hygrostat.
The algorithm allows not to activate the two relays simultaneously,
so as not to burden the electric line in the start-up phase (peak) of the
temperature and humidity control systems.
Practically, the activation is manages in a way not to have overlapping
on activation of the two commands.
