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

Research Products Corporation at (800) 334-6011.

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.

WIRE REQUIREMENTS

(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.

Figure 3

(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.

CAUTION

Minimize wire entry hole size and seal the hole – drafts from inside the wall could affect temperature readings.

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.
