HUMIDISENSE BYPASS INSTALLATION
EXTERNAL SWITCH - AIR PRESSURE SWITCH (Cycles humidifier whenever furnace fan runs
and humidistat calls for humidity) (Figure 3).
Figure 3
What you will need (sold separately):
1. Pressure switch PS221 (or any differential pressure switch).
2. Length of two conductor solid copper thermostat wire 18 gauge max (available at most
hardware stores).
3. Two 1/4" female electrical connectors (available at most hardware stores).
4. Mount the pressure switch on the hot air duct by drilling a small hole close to the pressure
switch (large enough for air sampling tube). Attach one end of the air sampling tube to the
positive pressure port on the pressure switch and insert the other end into the duct through
the hole drilled earlier.
5. Using the two 1/4" electrical connectors and thermostat wire, connect the pressure switch
"Common" and "Normally Open" terminals to the "Humidisense Bypass" terminals #3 and #4.
6. Change all the humidifier's DIP switches to the ON position.
HUMIDISENSE BYPASS INSTALLATION
Connecting Humidifier to Existing
Electronic Thermostat (Figure 4). This
allows the existing electronic thermostat
to control humidifier's cycles.
What you will need (sold separately):
1. 24 VAC NO relay, Packard PR380 (or
any 24 VAC NO relay).
2. Length of two conductor solid copper
thermostat wire 18 gauge max
(available at most hardware stores).
3. Four 1/4" female electrical connectors
(available at most hardware stores).
RELAY INSTALLATION
1. Confirm your electronic thermostat
is capable of controlling a central
humidifier and that it has the
necessary two conductor connections
for humidity control (confirm this with
the thermostat manufacturer).
2. Remove the existing humidistat from
the humidifier.
Model 5000: Remove the two wires
installed on the humidistat terminals.
Model 6000: Disconnect the two black transformer wires from the top panel and disconnect the
two red wires from the top panel to the humidifier's side panel.
3. Mount the 24 VAC relay close to the humidifier.
4. Connect the humidifier to the 24 VAC relay.
Model 5000: Connect the two wires removed from the humidistat in Step 2 to the
"Common" and "Normally Open" terminals.

Figure 4
Model 6000: Connect the two plug in transformer wires to the humidifier's side panel terminals
24 VAC IN. At the relay separate the plug in transformer wires. Referring to Figure 4, cut
one of the wires, strip the ends and using the 1/4" electrical terminals connect to the relay's
"Common" & "Normally Open" terminals.
5. Using two 1/4" electrical connectors, connect the coil terminals of the 24 VAC relay to the
electronic thermostat's humidity control terminals.
6. At the humidifier, change all the DIP switches to the "ON" position and install a jumper wire
across the humidisense bypass terminals #3 and #4.
HUMIDISENSE BYPASS INSTALLATION
24 VAC Thermostat Interlock (Cycles
humidifier whenever furnace is in heating
mode and humidistat calls for humidity)
(Figures 5 and 6).
What you will need (sold separately):
1. Length of two conductor solid copper
thermostat wire 18 gauge max
(available at most hardware stores).
2. Two 1/4" female electrical connectors
(available at most hardware stores).
24 VAC INTERLOCK INSTALLATION
1. Consult your furnace's installation
manual and or an HVAC professional.
Locate the furnace's control board
normally found in the bottom portion
of the furnace near the furnace blower.
Figure 6
2. Identify the 24 volt terminals which will be energized when the furnace is in heating.
3. On older boards there will be a set of terminals used to connect to the central thermostat,
these terminals are usually marked R, C, W, Y, G. On this type of board use the terminals
marked C (or Com) & W (or W1).
4. On newer boards there is a dedicated 24 volt humidifier terminal marked HUM or 24V HUM.
On this type of board use the 24 V Com & 24 V HUM terminals.
5. If you are unsure consult your furnace's installation instructions and or an HVAC professional.
6. Once you have identified the proper terminals use the 18 gauge thermostat wire to make the
connection from the furnace control board to the humidisense bypass terminals #1 & #2.
7. Change all the DIP switches to the ON position.
8. The humidifier will now cycle whenever the furnace heating relay is energized and the
humidistat is calling for humidity.
HUMIDISENSE BYPASS INSTALLATION
Hardwired Installation. Traditional Method (Figure 7) (Model 5000 ONLY, Cycles humidifier
whenever the furnace is in heating and the humidistat calls for humidity).
What you will need (sold separately).
1. Hardwire transformer 04A000200 (or other 120 Volt / 24 Volt hardwire transformer).
2. Length of white & black TEW 18 gauge wire (approx. 2ft).
3. Two 1/4" female electrical connectors (available at most hardware stores).
4. Wire Nuts & Electrical Tape.
