(Features Submenu Continued)
Double Mode (NH-EL 150-200 only)
Parallel = cylinders operate in parallel from one set of control signals.
Sequenced = cylinders operate in series from one set of control signals.
Independent = two sets of controls signals and each cylinder follows one of
the sets.
Manual Cap
Reduces the maximum capacity of the humidifier to a percentage of its full
capacity. Use up/down buttons to increase/decrease and press
checkmark to save the setting.
Ground FI
When “On” the contactor will be disengaged whenever the drain valve is
activated to prevent current leakage to the drain. (Default = Off).
Fill Stop
When activated during a fill cycle the fill valve will be turned off when current equals 95% of
demand to prevent overshooting the demand. (Default = Off).
Overcurr
Adjust only if instructed by NORTEC Representative. (Default = 0.00)
Low Conductivity
Prevents false “Spent Cylinder” codes. Set to On if water conductivity is below
250 microsiemens. (Default = Off)
Short Cycle
When “On” reduces the capacity if short cycling is detected. This will reduce the possibility of
short cycling. (Default = Off).
Controls Submenu
Control Settings allow you to set the type of external controls the humidifier is connected to. In
most cases, the NH-EL humidifier is factory configured to operate with the external controls that
were specified for the site.
Source
Configures the humidifier to either accept analog control signals from a
humidistat or digital signals from a Building Management System.
Control Mode
Configures the type of control used with the humidifier. RH (P) is
proportional only internal control based on a transducer signal. RH (PI) is
proportional control with an integral.
Control Channels
Configures the humidifier to either operate with a single channel (control
only) or dual channel (control and high limit).
Channel 1/2 Type
Configures the Volt or amp range of the control signal connected to Channel 1/2. Can be used
to configure the humidifier to be On/Off. However, Nortec recommends using the Security Loop
for On/Off applications.
CAUTION: Improper control configuration can result in over humidifying
which can result in damage to property.
