Index Parameter Description
Ea05 Modulating control
Set the set point, differential, min production, max production
Default:
Set point = 50%rH (42°C) (107.6°F)
Differential = 5%rH (5°C) (9°F)
Minimum production =25%
Maximum production = 100%
Range: 0-100
7.2.6 Integral function in probe control
If using a probe that is connected directly to the humidifier (control: humidity probe), the Integral (I)
control function can be selected. This means the humidity level over time can be considered, bringing
the value to the set point even when the proportional action (P) alone is null.
To activate the Integral function, set humidity control (single probe) on screen [Ea01]; also adjust the
proportional band on screen [Ea05] (for example, by setting it to a value of 50%). The proportional band
has to be at least 10% or higher, so that screen Ea05a will be visible. On screen [Ea05a], two parameters
can be set, “integral time” and “neutral zone”.
Index Parameter Description
Ea05a
Integral time
Integral time setting
Default: 120 s
Minimum: 0 sec (integral function disabled)
Maximum: 300 s
Neutral zone
Integral neutral zone setting, inside which gain remains constant
Default: 2.5%
Minimum: 0%
Maximum: 20%
7.2.7 Limit probe configuration (Installer menu)
A second probe can be connected as a limit probe at the outlet. This probe has the purpose of
preventing the relative humidity downstream of the steam distributor from exceeding a set value,
configured by the user. As this probe has a modulating action, the differential can also be set. The limit
probe, within its range of activation, has priority over the main probe (as the limit probe set point is
higher than the main probe set point).
Index Parameter Description
Ea06 Limit probe
Limit probe set point and differential
Default:
Set point = 100% rH
Differential = 5%
Range: 0-100
7.2.8 Boiler operating hours (Service menu)
The “Boiler op. hours” screen displays the effective number of boiler working hours.
Index Parameter Description
Ea07 Boiler operating hours
Display boiler operating hours, reset hour counter and set
maintenance pre-alert threshold
Default: Pre-alert = 240 hours
Range: 0-999
If the boiler needs to be replaced, the hour counter must be reset using the “Reset” parameter; the hour
counter will then start again from zero.
The “Pre-alert” item sets the maintenance pre-alert, which is activated “x” hours before the maintenance
alarm, and where “x” is the value set for the “Pre- alert” parameter. This allows time to plan the
