Warnings
Warnings do not stop the operation of the humidifier. Care should be taken to resolve the warning
messages before they develop into faults.
W1 Over Current detection
Current detected remains greater than 115% of default max current.
If the current is greater than 115% of the max output current/ full load (but less than 130%), the heat circuit de-
energizes and restarts again.
During the restart, the drain valve will pulse on and off while the fill valve and heating circuit remain inactive. After a brief
pause, the unit will resume normal operation and the cylinder will fill with supply water. This will reduce the current in the
water
Conductivity of the water in the cylinder is too high.
This warning may indicate poor filling and draining (blowdowns) that would normally reduce the conductivity of the
water. This warning may also indicate the presence of excess minerals in the supply water. Evidence may include the
presence of scale in the drain line, drain valve, or in the cylinder.
Ensure the drain line is not blocked, and the drain valve is functioning properly. Ensure that the water supply is within an
acceptable range, 125-1250 µS/cm.
Spent cylinder undetected.
The cylinder may be spent, and not detected by the software. Check for excessive scale, and replace the cylinder if
necessary.
Cylinder is filling too quickly.
Check the fill valve for defects, and replace if necessary.
Back pressure present.
Ensure the steam line has no low points or kinks, where condensate may form.
W2 Security Loop Open
External controls not wired properly.
- blinking quickly
Humidification disabled until the following conditions are met:
n
Limiter signal detected and greater than minimum.
n
Security Loop closed.
n
Air proving switch closed.
n
No system faults.
n
No system lockouts.
W3 Control Sensor Broken
Control (demand) sensor input (transducer or WiFi) is broken or not wired properly.
- yellow
For a transducer input signal, this warning will appear if the value of the transducer or WiFi signal is 5% of the full signal.
Check the connections between the humidifier and its sensors. This warning may indicate improper wiring, or a blocked
wireless signal. Reduce the length of wire between the humidifier and the sensor(s), or extend the range of your
wireless device, or remove obstructions between the humidifier and wireless access point.
