2.2 The HumiControl Controller
1: PRG - Access to most frequently used parameters.
Also resets alarm relay.
2: SEL - Displays unit of measure. Press for 2 seconds
to access set point. Press with PRG for 5 seconds to
enter parameters.
3: 

 - Displays control sensor value. In programming
mode increases value or moves to previous parameter.
4: 

 - Displays high limit sensor value. In programming
mode decreases value or moves to following parameter.
5: 2-1/2 digit display for values and parameters.
6: LED to indicate decimal point.
7: LED to indicate value must be multiplied by
1000.
8: LED to indicate dehumidify mode.
9: LED to indicate alarm.
10: LED to indicate humidifier is producing steam.
Flashing indicates lower than required production.
11: LED to indicate when unit is filling.
12: LED to indicate when unit is draining.
2.3 Start-up Procedure
After closing the external fused disconnect to put power to the humidifier, press the top (I)
part of the I/O switch on the side of the unit
Initially, all LEDs light - this lasts about 1-2 seconds.
Then the initialization phase begins with 3 dashes. During this phase
diagnostics are conducted. This phase lasts about 4 seconds.
After running the diagnostics, the unit will start operation and display either
the % of steam production (On/off and Modulating modes), the %RH (Stand-
Alone Modulating mode), or two dashes will light, indicating the humidifier is
disabled or in alarm. The alarm code will flash.
2.3.1 Starting with a new cylinder
When starting with a new cylinder, you should activate the cylinder cleaning function by pressing the SEL and


 buttons simultaneously for 2 seconds after the initialization phase. This forces the unit to open both the drain
and fill valves for 10 minutes to flush the lines, then fills and drains the cylinder 3 times to wash out any mold
release or dirt. Once started, this function can be stopped by pressing the SEL and 

 buttons simultaneously
for 2 seconds again.
When starting the unit with a new or empty cylinder, it may take a significant amount of time (hours) for the unit
to build up enough mineral concentration to reach rated capacity. This time can be shortened by the addition of
Alka-Seltzer or salt (teaspoon) through the steam outlet on top of the cylinder.
