- 1 - WARNING 1. 120 V olts 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 co[...]

- 2 - - 3 - 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 Zoned Comfort System). Figure 1 shows optional connections to both an outdoor temperature sensor and an Aprilaire ® Automatic Digital Humidifier Control ([...]

(2) OPEN THE THERMOST A T 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 - - 5 - CAUTION Loss of internal programs may result from static dischar[...]

If installing this thermostat as part of a Model 6504 Intelligent Zoned Comfort System, refer to the Model 6504 Installation Manual for wiring and checkout procedures. Continue Model 6504 installation with Step 11 (page 36). If wiring this thermostat directly to the HV AC equipment or standard zone control panel, continue with Step 5. - 6 - - 7 - ([...]

The ADHC uses its own outdoor temperature sensor , which can be read by the thermostat. 1. Mount the outdoor temperature sensor (see Figure 7 ). • Locate on the N[...]

Figure 8 - 21 - - 20 - 2. Run a 2-wire cable from the sensor to the thermostat. 3. T ake a resistance measurement before connecting to the ODT and CIR GND terminals to verify the sensor is properly installed. Measure the wires at the thermostat to account for wire splices. • Use an ohmmeter to measure the resistance (k Ω ) of the sensor . The r[...]

Symptom Cause Miswiring – Check wire colors to verify A at ADHC is connected to ZA at thermostat and B is connected to ZB. No RH display , no outdoor ADHC power source – When wired to the Model 8570 thermostat, the ADHC temperature display must be wired to a continuously ON power source. Use voltmeter to verify presence of 24V AC (nominal) at A[...]

Symptom Cause Thermostat does not call for heat Minimum-off times. Change the mode to OFF first, then change the mode to HEA T and make a call for heat. Heating does not come on at all RH terminal not connected – see wiring diagrams. Heating equipment power not on. High Balance point limit – set balance point to OFF during system checkout. Auxi[...]

- 32 - - 33 - Symptom Cause Thermostat does not call for cooling Minimum-off times. Change the mode to OFF first, then change the mode to COOL and make a call for cooling. Cooling does not come on at all RC terminal not connected – see wiring diagrams. Cooling equipment power not on. Heat comes on instead of cooling O/B dip switch not set properl[...]

- 34 - - 35 - Symptom Cause Thermostat does not call for heat Minimum-off times. Change the mode to OFF first, then change the mode to EMERGENCY HEA T and make a call for heat. Emergency Heat does not come on at all RH terminal not connected – see wiring diagrams. Heating equipment power not on. Fan comes on before heat starts, or Change position[...]

2. DIFFERENTIALS 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 . If the second stage differential is [...]

5. PROGRESSIVE RECOVERY Progressive Recovery causes the thermostat to bring on the heating/cooling equipment before the programmed event start time, in order for the temperature to be at the programmed value by the programmed time. The feature can be turned on or off. When turned off, the heating/cooling equipment will not begin bringing the space [...]

7. INPUT DEALER CONT ACT INFORMA TION During thermostat operation, the two multi-function buttons are labeled INFO and MENU. When the INFO button is pressed, the thermostat will display the humidity and temperature sensed by the ADHC (if an ADHC has been installed), then the thermostat will display any monitor messages and dealer contact informatio[...]
