Wall Mount Humidity Controller
Combination controller and room humidistat.
Run control wires directly to HROB unit.
Applications
• Neptronic SKR, SK300, SKE, and SKG humidifiers
• Other humidification and dehumidification applications
Ramps
• LSS: External Demand Low Signal Selector
Compares selected input signals to select the
lowest signal.
• AER: External Humidity Sensor Averaging
Calculates an average of selected input signals
• DUC: Duct Supply Input
Two PID loops and a zero/span to smooth out the
demand signal
• DED: External Demand Signal
Control using an external demand of 0-10Vdc or
2-10Vdc
• HIL: High limit
Compares the demand of the room humidity PID
loop with the duct/high limit PID loop and applies
the lower of the two.
