[S9=7] Functioning with integrated thermostat (ON/OFF hot call):
This type of operation involves the production of steam in only 2 modes: no production or
production at full capacity set (Pr parameter) which is activated when the temperature measured
by the ambient probe falls below the value of SET POINT-r1 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 Master HUM2 electronic board.
(r1=Temperature differential referred to set point)
In this mode, it is possible to set the two configurable outputs (Do4 and Do5 already wired on
terminals 62 and 63, in tension) to manage a few typical functions of a sauna or a Turkish bath,
such as the essence inlet, the management of outlet or inlet fans.
Essence Management (dO4 or dO5 = 4):
In a Turkish bath the essence is provided (with the times set in t2 and t3) when the humidifier is
producing steam and the temperature measured by the ambient probe is higher than 70% of the
set point. By using the key combination arrow up + Stand-by is possible at any time to enable or
disable the inlet of the essence; in particular, the current status is displayed after pressing
the key combination for three seconds (
EoF
= essence OFF or
Eon
= essence ON) and by
continuing to hold the keys pressed for another three seconds, the state is switched.
Inlet fan (dO4 or dO5 = 3):
The inlet fan is usually used to introduce or mix the steam in the room. The relay linked to this
function is activated when there is a steam production request (it remains active even during the
phases of water discharge for deconcentration or due to overcurrent) and it is deactivated with
the delay set in parameter t6 after the end of the steam production request. If parameter t6 is set
to -1, the inlet fan run in continuous gear (active even during stand-by or alarms).
Outlet fan (dO4 or dO5 = -3):
The outlet fan is usually used to ensure air exchange and to create the fog effect. The relay
linked to this function is activated when there is no steam production request. It is also possible
to start a drying cycle at the end of the day; with the humidifier in stand-by, press the keys
arrow down+Stand-by to activate the cycle that is indicated on the display with the writing
Uon
= outlet fans ON. In this phase the output of the outlet fan remains active for the hours set
in the variable t4. To stop this cycle, simply exit the stand-by status.
