Disconnect electrical power to the furnace and air conditioner 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. MODEL 8870 THERMOSTAT SPECIFICATIONS: Control Voltage 24V AC ±20% Switched Voltage 18 – 30V AC Maximum Operating Current 2.0A total at rated voltage, through all outputs. 1.0A through any one output. Maximum Surge Current 2.0A Control Accuracy ±1.0°F Control Range 40° – 90°F Operating Range 32° – 99°F 1. HVAC SYSTEM PRE-INSTALLATION CHECK LIST Before getting started determine what type of heating system is/will be installed in the house. Then use Table 1 to determine if the proper numbers of wires are available depending on the HVAC System. Additional wires will be required for communication system.

WHAT’S IN THE BOX • Thermostat (Figure 1 ): front panel, cover, and base • Installation Manual • Owners Manual • Hardware bag: screws and wall anchors FIGURE 1 3. SELECT THE THERMOSTAT LOCATION Determine if the thermostat will be operating alone, or with remote temperature sensors. If the unit is stand-alone there are certain measures that must be taken to ensure accurate temperature control. STAND-ALONE THERMOSTAT MOUNTING CRITERIA: • Mount on an interior wall. • In a room frequently occupied. • At least 18 inches from any outside wall. • Approximately 5 feet above the floor. Check with local building codes for height requirements in commercial requirements. 3 Front Panel Cover Base DO NOT locate the thermostat: • Behind doors, in corners or other dead air spaces. • In direct sunlight or near lamps, appliances or other sources of radiant heat. • On an outside wall or wall exposed to an unconditioned space (i.e. garage, etc.). • In the flow path of a supply register, in stairways or near outside doors. • On a wall where concealed pipes and/or ductwork will affect the thermostat. • Near sources of electrical interference such as arcing relay contacts. WITH REMOTE TEMPERATURE SENSORS Follow the guidelines for placement of the sensors and locate the thermosta...
