Page 6: Wire Requirements
WIRE REQUIREMENTS 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. -
Page 7: Select A Mounting Location
(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) –... -
Page 8: Open The Thermostat
(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). CAUTION Figure 3 Loss of internal programs... -
Page 9: To The Wall
(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. -
Page 10: Set The Configuration Dip Switches On The Thermostat Circuit Board
(4) SET THE CONFIGURATION DIP SWITCHES ON THE THERMOSTAT CIRCUIT BOARD 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. - Page 11 6504 or AHC – This switch is used to configure the thermostat installation as part of a Model 6504 Intelligent Zone System. • Set to 6504 only if installing as part of a Model 6504 Intelligent Zone System. • Set to AHC if the thermostat is to be wired to the HVAC equipment or standard zone system.

Page 20: Temperature Sensor
(6) OPTIONAL – INSTALL AN APRILAIRE MODEL 8052 OUTDOOR TEMPERATURE SENSOR Note: If an AHC is to be installed, do not wire an outdoor temperature sensor– see Step 7. The AHC uses its own outdoor temperature sensor, which can be read by the thermostat. - Page 21 2. Run a 2-wire cable from the sensor to the thermostat. CAUTION Do not run the wire along side line voltage (120 VAC) or higher lines as this can cause erratic readings. 3. Take a resistance measurement before connecting to the ODT and CIR GND terminals to verify the sensor is properly installed.

Page 23: Optional - Install An Automatic Humidifier Control (Ahc)
(7) OPTIONAL – INSTALL AN AUTOMATIC HUMIDIFIER CONTROL (AHC) Note: The AHC uses its own outdoor temperature sensor, which is read by the thermostat. If an AHC is to be installed, do not wire an outdoor temperature sensor to the ODT terminal of the thermostat. - Page 24 Figure 8 AUTOMATIC MODE B2203201 Rev. B AHC must be powered by a continuous supply – do not wire to furnace accessory terminals. - 20 -...

Page 25: Optional - Install An Indoor Temperature Sensor
(8) OPTIONAL – INSTALL AN APRILAIRE MODEL 8051 INDOOR FLUSH MOUNT TEMPERATURE SENSOR 1. Mount the indoor temperature sensor. • Locate the sensor as you would locate a thermostat. • Maximum wire length from sensor to thermostat is 300 feet. - Page 26 Figure 9 - 22 -...

Page 28: Verify Outdoor Temperature Sensor
1. PLACE THE THERMOSTAT ON THE BASE. 2. TURN ON POWER TO THE HVAC SYSTEM. • The display will show the Aprilaire screen for approximately 5 seconds (up to 10 seconds if installed as part of a Model 6504 Intelligent Zone System). - Page 29 Miswiring – Check wire colors to verify I- at AHC is connected to I- at thermostat and I+ is connected to I+. AHC power source – When wired to the Model 8570 thermostat, the AHC must be wired to a continuously ON power source. Use voltmeter to verify presence of 24VAC (nominal) at AHC.

Page 34: Customize The Application Settings
(10) CUSTOMIZE THE APPLICATION SETTINGS 1. DIFFERENTIAL Determines the temperature above/below the temperature setting at which the heating or cooling equipment will turn on. For example, a heat temperature setting of 70°F with a differential of 2° will result in the equipment turning on and off to maintain the temperature between 68°F and 70°F. -
Page 35: Offset
2. OFFSET All thermostats are factory calibrated to be accurate to within ±1° of true temperature. An offset is available to allow for agreement with field temperature measuring instruments. The value set will be added to the temperature sensed by the thermostat. -
Page 36: Balance Points (Heat Pumps Only)
4. BALANCE POINTS (HEAT PUMPS ONLY) This feature is only available when the thermostat has been configured to operate heat pumps (see SET THE CONFIGURATION DIP SWITCHES on page 6) and only when an outdoor temperature is available to the thermostat. Outdoor temperature can come from an AHC or from an outdoor temperature sensor. -
Page 37: Input Dealer Contact Information
AHC (if an AHC has not been installed the Aprilaire logo screen will appear), then the thermostat will display the thermostat model number and contact information. At installation, the contact information is blank and only the thermostat model number appears. -
Page 38: Blower Extension For Humidity Control
6. BLOWER EXTENSION FOR HUMIDITY CONTROL If the heating equipment has not run long enough to allow the humidifier to meet the humidity demand, the thermostat will continue the blower after a heat call. One second before the thermostat turns off the heating terminal(s), the fan terminal will be energized thus extending blower operation. -
