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. All wire is standard 18-24 gauge thermostat cable. Application # Wires Diagram (Page) Figure 1 – Thermostat Wire Singl

(1) SELECT A MOUNTING LOCATION If installing the thermostat alone… If installing an indoor temperature sensor… • Mount on an interior wall, in a frequently occupied space. • Mount the thermostat where it can be readily accessed. Note that the backlighting illuminates whenever a button • Keep the thermostat 18" from an outside wall. is pressed. • Mount the thermostat approximately 5 feet above the floor. • Thermostat can be mounted on a vertical junction box (j-box). Height requirements are dif

(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 may result from static discharge to thermostat circuit board. Avoid touching the circuit board and touch a grounded metal object before handling the thermostat. USE THE SCREWDRIVER TO SE

(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) Figure 4 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. W2 • Drill a 3/16" hole for wall anchors. W1 RH R • Drill a 3/32" starter hole for screws only. RC G 3. For junction box mounti

(6) OPTIONAL – INSTALL AN APRILAIRE MODEL 8052 OUTDOOR TEMPERATURE SENSOR Note: If an AHC is to be installed, do not wire Figure 6 an outdoor temperature sensor– see Step 7. The AHC uses its own outdoor temperature sensor, which can be read by the thermostat. 1. Mount the outdoor temperature sensor NORTH, EAST (see Figure 6). OR WEST SIDE • Locate on the North side of the building if OF BUILDING possible. East and West are acceptable locations as long as the sensor will not be exposed to dir
