Aprilaire 60 Automatic Digital Humidifier Control Humidistat Instruction Manual

Aprilaire 60 Automatic Digital Humidifier Control Humidistat

GETTING STARTED

STEP 1: Unpack the Humidifier Control Carton
Make sure all components are present (see Figure A):

• A. Humidifier control
• B. Outdoor temperature sensor
• C. Manual mode label

STEP 2: Disassemble the Humidifier Control
Remove the knob. Remove the cover by pulling at the bottom and swinging it out and upward. See Figure B to become familiar with the terminal positions. Figures K and L show complete installation wiring diagrams for Aprilaire humidifiers.

STEP 3: Set the Change Water Panel Indicator
This setting will control when the indicator light turns on, reminding you to change your water panel. If your control came with a humidifier, the control is pre-set for the humidifier. If the installation site has a 3-month or shorter heating season or very hard water, you may want to adjust the setting. The Model 62 shipped with the Model 800 steam humidifier is factory set to “OFF.” The Model 62 does not have the “Change Water Panel” light on the control. The canister change indicator for the Model 800 is on the humidifier.

STEP 4: Blower Activation Feature Explanation
The Blower Activation switch is set to the “ON” position to allow the humidifier control to activate the HVAC fan for maximum humidification. For this setting, the Models 500, 600 and 700 must be connected to hot water. If the HVAC system has been idle for 1 hour, the humidifier control will activate the HVAC system fan to sample the air for 3 minutes. If the RH is lower than the set point, the humidifier control will activate the humidifier and keep the fan running. The humidifier will continue to operate for 2 hours or until the humidification set point is reached. If the RH set point has not been reached by the end of a call for heat, the control will continue to operate the humidifier and the HVAC fan until the humidification set point is reached or 2 hours have elapsed. When the Blower Activation switch is in the “OFF“ position, the humidifier control will only operate the humidifier if humidity is required and the HVAC system fan is operating or the HVAC system is producing heat.

NOTE : If used in conjunction with an Aprilaire 8570 Communicating Thermostat, and the Blower Activation feature is desired, DO NOT wire the A B communication terminals.

INSTALLATION

STEP 1: Mount the Humidifier Control
Humidifier control must be mounted on the return duct, at least 6 inches upstream of the following (see Figure D):

• Humidifier
• Humidifier bypass ductwork (if applicable)
• Fresh air intake ductwork (if applicable)

For accurate humidity control, mount the humidifier control at least 12 inches upstream of the steam humidifier dispersion tube. Ambient operating temperature of the humidifier control is to be from 20°F to 120°F to prevent damage to the control display.

DUCT (SHEET METAL) MOUNT:

• After location for control is selected, drill a 3/4 inch hole for the
• RH sensor (the RH sensor extends from the back of the humidifier control).
• Use 2 sheet metal screws, 3/4 inch long (not provided), to mount the humidifier control. Use the mounting slot to level the control, then secure the control with the second sheet metal screw.
• Make sure the humidifier control sensor gasket is seated tightly around the drilled hole. Do not install control without the gasket.

DUCT (FIBER BOARD) MOUNT:

• After location for control is selected, cut a rectangular hole in the duct board, no smaller than 6-9/16 inches long by 4-3/8 inches wide.
• Cut a rectangular piece of sheet metal to fit behind the hole in duct board for mounting the humidifier control.
• Drill a 3/4 inch hole for the RH sensor (the RH sensor extends from the back of the humidifier control) into the sheet metal plate.
• Use 2 sheet metal screws, 3/4 inch long (not provided), to mount the humidifier control.
• Make sure the humidifier control sensor gasket is seated tightly around the drilled hole. Do not install control without the gasket.
• Secure the sheet metal plate, with the humidifier control mounted, inside the duct (see Figure E).

CONTROL REPLACEMENT

When replacing an existing control, the duct opening left by the removed control must be covered completely. Locate and install the new control as instructed previously in this step

STEP 2: Determine Location for and Mount Outdoor Temperature Sensor
The location of the outdoor temperature sensor must meet these 3 requirements:

• Must be mounted on north, east or west side of house out of direct sunlight.
• Must be at least 3 feet from all exhaust vents.
• Must be above expected snow line.
• Incorrect humidity levels will result if these requirements are not met.
• Secure sensor bracket with a #8 galvanized screw.

NOTE: A convenient way to get the sensor wire outside is to make use of unused wires running to the A/C condensing unit (if applicable). Other ways are to use existing holes for cable TV lines, telephone lines, A/C lines, etc. Read all equipment instructions beforehand for possible conflicts and warnings.

STEP 3: Alternate Location for Outdoor Temperature Sensor

• When mounting the outdoor temperature sensor (ODT) in an intake air duct, turn the Blower Activation switch to “OFF”

• If left in the “ON” position, over-humidification and condensation damage could occur.

• The sensor can be mounted with a #8 galvanized screw in the center of either:

• PVC fresh air intake pipe for the HVAC system

• A fresh air intake duct

• In both cases, the sensor must be no more than 3 feet from the outside wall.

• If it is not feasible to use the outdoor temperature sensor in any of the ways described, the humidifier control can be installed for manual operation.

• See “Installing the Humidifier Control for Manual Operation” and Figure J for details.

STEP 4: Route the Wire from Control to Sensor

• Run wire to the ODT. Sensor is accurate with lead lengths up to 300 ft.

STEP 5: Attach Sensor Wire to Humidifier Control

• Strip wire 1/4 inch, and insert the wires from the sensor into the terminals labeled “ODT” on the humidifier control.

Installing the Humidifier Control for Manual Operation

• If it is not feasible to install the ODT, the humidifier control can be operated in Manual Mode.
• Position the mode switch in the “MAN” position. Manual indicator “M” will be displayed.
• Apply the “Manual Mode” label to the cover, aligning the sticker and knob holes.
