WARNING
1. 120 Volts may cause serious injury from electrical shock. Disconnect electrical power to the HVAC equipment before
starting installation. This thermostat is not a 120-volt (line voltage) device.
2. Improper installation may cause serious injury from electrical shock. This product must be installed by a qualified
heating and air conditioning contractor in accordance with NEC Standards and applicable local and state codes.
3. Mercury is toxic and may be hazardous to health. Any replaced thermostats containing mercury must be disposed of
properly. Contact local authorities for disposal information.
Read this Installation Manual before beginning installation of the Aprilaire®8570 Thermostat. For questions call

Figure 1 and the table show the number of wires that must be available at the thermostat in stand-alone thermostat systems (i.e. not as
part of an Aprilaire®Model 6504 Intelligent Zone System). Figure 1 shows optional connections to both an outdoor temperature sensor and
an Aprilaire®Automatic Humidifier Control (AHC), but only one or the other can be used. All wire is standard 18-24 gauge thermostat cable.
When this thermostat is connected to a Model 6504 as
shown in Figure 2, only one four-wire cable need be run
from the thermostat to the Model 6504. Use standard
18-24 gauge thermostat cable.

(1) SELECT A MOUNTING LOCATION
If installing the thermostat alone…
• Mount on an interior wall, in a frequently occupied space.
• Keep the thermostat 18" from an outside wall.
• Mount the thermostat approximately 5 feet above the floor.
Height requirements are different for compliance with the
Americans with Disabilities Act (ADA) – 48" maximum height
for forward reach and 54" maximum height for side reach.
• Thermostat can be mounted to a vertical junction box (j-box).
• DO NOT mount the thermostat:
– behind doors, in corners or other dead air spaces.
– in direct sunlight or near lamps, appliances or other
sources of heat.
– on an outside wall or wall exposed to an unconditioned
space (i.e. garage).
– in the flow path of a supply register, in stairways or near
outside doors.
– on a wall where concealed pipes or ductwork could
influence the sensor.
– near sources of electrical interference such as arcing
switch contacts.
If installing an indoor temperature sensor…
• Mount the thermostat where it can be readily accessed.
Note that the backlighting illuminates whenever a button
is pressed.
• Thermostat can be mounted on a vertical junction box (j-box).
• DO NOT mount the thermostat where the operating range
temperatures will be exceeded (i.e. attic or unventilated
equipment room).
• Mount the sensor in the same location as if installing a
thermostat alone.
(2) OPEN THE THERMOSTAT
Use your hands to pull the thermostat face off of the base. Separate one side at a time. There are latches on
either side of the thermostat.
If needed, the thermostat can be pried from the base by inserting a flat-head screwdriver (see Figure 3).
- 4 -
CAUTION
Loss of internal programs
may result from static
discharge to thermostat
circuit board. Avoid
touching the circuit board
and touch a grounded
metal object before
handling the thermostat.
INSERT SCREWDRIVER INTO 1 OF
4 SLOTS (2 ARE ON THE TOPSIDE,
2 ARE ON THE BOTTOM SIDE)
USE THE SCREWDRIVER TO SEPARATE THE
HOUSINGS. REPEAT ON THE REMAINING 3 SLOTS.
NOTE: THE HOUSINGS WILL NOT COMPLETELY
SEPARATE. PULL THE HOUSINGS APART WITH
YOUR HANDS TO COMPLETELY SEPARATE.

(3) MOUNT THE THERMOSTAT BASE TO THE WALL
1. Place the wire opening in the base over the wire entry
hole in the wall. Level the base (for appearance only)
and mark the screw locations. See Figure 4.
2. Use the supplied screws and wall anchors to mount
the thermostat to the wall. It is recommended that wall
anchors be used for installation to drywall/sheet rock.
• Drill a 3/16" hole for wall anchors.
• Drill a 3/32" starter hole for screws only.
3. For junction box mounting, screws are field supplied.
The thermostat can be installed on a vertical j-box.
4. Seal the wire entry hole(s) with caulk, drywall putty
or insulation to prevent drafts from inside the wall
cavity from affecting thermostat performance.

Figure 5
There are four dip switches
located on the back of the
thermostat (on the circuit
board) that must be set to
properly configure the
thermostat for operation
with the equipment it is to
control. Figure 5 shows
the default position for the
four switches.
