  6. Install digital humidistat on wall in living area.

WARNING! Installation involves electrical and plumbing work. If unsure, hire a qualified HVAC technician.

First-Time Setup

After installation, power on and configure settings.

  1. Set desired humidity: Use humidistat dial or buttons (recommended 35-45% RH).
  2. Test operation: Turn furnace fan to ON; check for water flow and drainage.
  3. Calibrate humidistat: Compare with separate hygrometer if needed.
  4. Set seasonal settings: Lower humidity in colder outdoor temperatures.

CAUTION! Do not set humidity too high in cold weather to prevent window condensation.

Specifications

Controls and Settings

Digital Humidistat: LCD shows current and set humidity, system status.

Buttons: UP/DOWN to set humidity, FAN (ON/AUTO), SYSTEM (OFF/HEAT/COOL if connected).

Settings: Humidity setpoint (20-60% RH), Fan control (continuous or automatic with furnace), Outdoor temperature sensor (if equipped), Manual override for continuous operation, Filter change reminder (if equipped).

Connecting to HVAC System

Connect to furnace control board or 24V transformer.

  1. Turn off furnace power.
  2. Locate humidifier terminals on furnace control board (HUM or similar).

  4. Connect humidistat wires to humidifier or control board.
  5. Restore power and test.

Tip: Refer to furnace manual for specific terminal designations.

Operation and Maintenance

Automatic operation based on humidistat setting.

  1. Normal operation: Humidifier runs when furnace fan runs and humidity is below setpoint.
  2. Check water flow: Ensure water is flowing to panel during operation.
  3. Monitor drainage: Drain should have steady stream during operation.
  4. Seasonal shutdown: Turn off water supply and power at end of season.
  5. Annual maintenance: Clean cabinet, check for scale, replace water panel.
