HCSTEAM−16/−35 SERIES
During cleaning, the electrodes are powered and water fills
until it touches the high−level sensor or the phase current
equals 20A, whichever occurs first. After either of the
events is detected, the steam cylinder is fully discharged
with the electrodes un−powered (the drain pump and the
drain tempering valve are activated for 3 minutes). Lennox
recommends to perform two cleanings when starting a
new humidifier. After the cleaning ends, the humidifier
starts regular operation. The HCSteam−16/−35 humidifier
is now ready for operation.
Operation
Amperage: the amount of current
flowing through the water causing
the water to heat, boil, and pro-
duce steam (default display).
Production %: the amount of
steam being produced (ex-
pressed as a percentage of the
humidifier’s capacity).
Hour counter, expressed in tens;
for instance, when the display
shows 13 the real hour value will
be between 130 and 139 hours.
(Amperage is repeated)

By pressing the
reset/sel
" button for 2 seconds, the dis-
play will loop from amperage to production in % of the max-
imum production to the hour counter and back to amper-
age (see figure 21).
Selecting the signal type
NOTE − The HCSteam−16/−35 humidifier is preset for a
manual humidistat with only an ON/OFF feature and nor-
mally does not require any change. Should the need ever
arise to reset it, proceed as follows:
1. Switch the humidifier off.
2. While pressing and HOLD-
ING both
reset/sel
" and
drain
" buttons, switch the
humidifier back on. DO NOT
release
reset/sel
" and
drain
" buttons until the
wrench icon blinks; then re-
lease both buttons.
3. Press
reset/sel
" until the display shows
02. DO NOT confirm any value higher than
02. Values of 03 or higher not applicable for
these models. If value is higher than 02,
press
reset/sel
" until the display goes
back to the normal operating mode and re-
start from step 1.
4. Press and hold
drain
" (mini-
mum 1 second); the display
shows P1" then the present
signal type and then set"
.
5. Press
reset/sel
" for signal type of 0 or 1:
0 = On−Off humidistat
1 = external 0...10 Vdc modulating signal
humidistat.
6. Press and hold
drain
" (minimum 1
second) when done to confirm the new
value of P1 and exit to the normal op-
erating mode.
7. Switch the humidifier off.

Changing the maximum production percentage
The maximum production can be adjusted between 20%
and 100% of the nominal production in steps of 5% in order
to suit either the 110−120 VAC or 220−240 VAC unit. Default
settings are factory set at 100% (110−120 VAC unit) 70%
(220−240 VAC unit). Adjust capacity per humidity calcula-
tion or system application air flow. Table 3 shows the hu-
midification load requirements. This chart will be helpful in
setting the correct production percentage.

age and then set".
5. Press

Maximum Production in steps of
5% between 20% and 100%.
6. Press and hold
