Cause:

1. Incorrect air switch setting
2. Incorrect air switch wiring
3. Faulty air switch
4. Blower problem. Faulty controller

Solution:

1. Contact NTI technical support.
2. Check that the red and orange wires are connected to quick connect tabs 3 and 1 respectively.
3. Disconnect red and orange wires from air switch and check for open circuit between terminals 1 & 3. If continuity detected, replace air switch.
4. Check low voltage wiring from blower to controller. Check VDC signal from red–green and black-green; if not 28-32VDC and 0 VDC respectfully – replace controller. If signal is correct – replace blower.
