HUMIDISTAT OWNERS MANUAL

229100

INSTALLER: PLEASE LEAVE OWNERS MANUAL WITH HOME OWNER.

I. SAFETY

WARNING! Improper electrical wiring can result in fire or loss of humidity control. Disconnect electrical power before installing and servicing. Failure to disconnect electrical power may result in injury or death. The wiring must conform to all building codes and ordinances as required by local and national code authorities having jurisdiction for this installation.

The 229100 must be installed by a qualified Technician. Failure to properly install the 229100 may result in property damage or personal injury.

Homeowners must read instructions and understand the operation of the

229100 and the humidifier(s) it controls.

Improper operation can result in over or under humidification. Over humidification can result in condensation, structural damage and mold.

Condensation within a building's structure can cause loss of structural strength. Condensation can also enable mold and mildew growth resulting in personal injury and damage to building structure and contents.

II. APPLICATION

The 229100 humidistat provides low voltage control of humidifiers installed in central heating systems. The humidistat has a SPST switch and is designed for mounting on the return air duct.

RANGE: 10% to 85% RH ELECTRICAL RATING: 30 VAC / 60 VA

OPERATION

Set the control knob to the desired humidity setting. The recommended setting for optimum humidification is 30% to 50%. The vertical position on the knob is approximately

42% RH.

Setting the humidistat above or below the recommended settings may not provide satisfactory results for your home.

III. INSTALLATION INSTRUCTIONS

PRECAUTIONS

The installer must be a qualified technician. Disconnect electrical power before beginning installation. Do not install the humidistat on the warm air duct. Conduct a thorough checkout before leaving the installation.

DUCT MOUNTING ON THE RETURN AIR - PREFERRED METHOD

Do not install the humidistat on the warm air duct or within 48” of UV light.

1. Locate the humidistat at least 24" upstream of the humidifier or

bypass on the return air duct. Avoid areas of direct radiation like

secondary heat exchangers in the fan compartment.

2. Remove face by inserting screwdriver into pry slot and twisting

(see fig 2)

3. Use the plastic duct mount plate as a template. Accurately mark and

drill the (4) 3/32”mounting holes and cut away the 4-1/4” x 2-1/2”

section of the duct inside the duct mount plate.

4. Place duct mount base gasket on the humidistat base and mount the

base with four screws. Low voltage wire may enter the humidistat

under the gasket (see fig 2).

5. Connect wires to screw terminals on the control assembly as shown in

wiring diagrams. Replace face and knob.

WALL MOUNTING INSTRUCTIONS

NOTE: Requires wall mount kit (Model 229110)

1. Chose a location for the 229100 about five feet above the floor

on an inside wall with average room temperature and relative

humidity conditions.

2. Drill a small hole in the wall and run low voltage wiring to the

location chosen. Pull about 6” of wire through the hole. Use the entire

mounting gasket (both inside and outside portions) to seal the wall

opening or use foam tape to prevent drafts from affecting the

humidistat operation. (see fig. 3)

3. Remove the knob on the humidistat. Squeeze the top and

bottom of the base to release the face of the humidistat.

4. Mount the base horizontally over the wires. Attach directly to

the wall, using the two screws provided in the slotted holes.

5. Connect wires to screw terminals on the control assembly as

shown in wiring diagrams. Replace face and knob.

WIRING

WARNING!

Disconnect electrical power before beginning installation.

The wiring must conform to all building codes and ordinances as required by local and national code authorities having jurisdiction for this installation.

Refer to the following wiring diagrams.

CHECKOUT

With furnace in operation, turn humidistat to "ON" position. Observe humidifier operation.

SETTINGS

WARNING!

Do not set relative humidity too high during cold weather. Over humidification can result in condensation, structural damage and mold.

Condensation within a building's structure can cause loss of structural strength. Condensation can also enable mold and mildew growth resulting in personal injury and damage to building structure and contents.

Refer to OPERATION for proper settings.

TROUBLESHOOTING

SYMPTOM DIAGNOSTIC STEPS

No Humidifier

Operation in

"ON" position

1. Set thermostat to operate both furnace burner and blower.

Operation may be necessary for system power.

2. Check voltage at humidifier control terminals.

There should be no voltage for Power Humidifier.

Voltage should be 20-30 VAC for most others.

3. Inspect humidifier wiring. Refer to wiring diagrams.

DO NOT LEAVE IN "ON" POSITION, OVER HUMIDIFICATION WILL OCCUR.

Humidifier operation in

"ON" position only

1. Humidity level in the home is higher than knob setting.

Humidifier control will not operate the humidifier until

humidity level is reduced.

Humidifier operation continuous

1. When the humidity in the home is less than the knob

setting, the control will operate humidifier until the

humidity is higher. Reduce knob setting.

2. Use "ON" position. Verify that the humidifier operates.

3. Remove wires from control terminals. If humidifier

continues to operate, check solenoid valve.

Humidifier turns on and off repeatedly

1. Check voltage at humidifier control terminals.

There should be no voltage for a Power Humidifier.

Voltage should be 20-30 VAC for most others.

2. If mounted on return air duct, make sure humidifier control

is at least 24" upstream of humidifier's air discharge.

PRECAUTIONS

The installer should be a qualified Technician. Disconnect electrical power before beginning installation. Use contacts C and NO for humidifier operation. Use contacts C and NC for a dehumidifier. Conduct a thorough checkout before leaving the installation.
