- [S9=7] Functioning with integrated thermostat (ON/OFF hot call):
This type of functioning envisions steam output in 2 ways only: no output or maximum output
activated when temperature measured by the Ambient probe drops below the SET POINT-r1
value and remains active until the temperature increases and exceeds the SET POINT.
Set the second level variable S9=7 and connect the NTC temperature probe to clamps 18 and 19
of the MasterHUM2 board.
(r1=Temperature differential referred to set point)
In this mode, it is possible to set the two configurable outputs (Do4 and Do5) to manage a few
typical functions of a sauna or Turkish bath, like the supply of essence, the managing of inlet or
outlet fans.
Essence Management (dO4 or dO5=4):
In a Turkish bath, the essence is supplied (with times set in t2 and t3), when the humidifier is in
steam output and the temperature detected by the ambient probe is above 70% of the set point
set. By means of the arrow up+Stand-by combination keys, it is possible at any moment to
enable or disable the essence supply, in particular after having pressed the combination keys for
three seconds, the current status is displayed (EoF = essence OFF or Eon = essence ON) and by
keeping the keys pressed for a further three seconds, the status changes.
Inlet fan (dO4 or dO5=3):
The inlet fan is normally used to introduce or mix the steam in the room. The relay coupled with
this function excites in presence of steam output request (it remains active also during the
discharge phases for deconcentration or overcurrent). Alternatively, clamps 62 and 63 are
present on the ES models, with a 230Vac voltage with steam output in progress (powered
electrodes) and used for connection of the PEGO fan unit accessory.
Outlet fan (dO4 or dO5=-3):
The outlet fan is normally used to guarantee air change and create fog effect. The relay coupled
to this function excites when there is no steam output request. It is also possible to launch a
drying cycle at the end of the day; with humidifier in stand-by, press the arrow down+Stand-by
keys to activate the cycle, with the display signalling Uon = outlet fans ON. In this phase, only
the outlet fan output remains active for the hours set in variable t4. To interrupt this cycle exit
stand-by.
