Recycling Thermostat If this thermostat is replacing a thermostat that contains mercury in a sealed tube, do not place your old thermostat in the garbage. Contact your local waste management authority for instructions regarding proper disposal of the thermostat. If you have any questions, call Robertshaw technical support at 1-800-445-8299. Step 2: Installing Model 9400 Thermostat NOTE: FOR NEW INSTALLATIONS, MOUNT THERMOSTAT ON INSIDE WALL, FIVE FEET ABOVE THE FLOOR.

5. Place thermostat against the wall at desired location. Make sure wires will feed through opening (Figure 4) on base of thermostat. 6. Mark placement of mounting holes (Figure 4). Set base aside. Mounting Holes GAS RESET NON-HP ELEC HP Wiring Opening Figure 4 7. If mounting on drywall, tap plastic anchors into wall. NOTE: ENCLOSED PLASTIC ANCHORS DO NOT REQUIRE A DRILLED HOLE FOR DRYWALL. 8. If mounting on a surface other than drywall, drill the marked holes using a 3/16" drill bit. 9.

Step 3: Testing the Thermostat ! WARNING: DO NOT SHORT (JUMPER) ACROSS TERMINALS OF GAS VALVE OR SYSTEM CONTROL TO TEST OPERATION. THIS WILL DAMAGE THE THERMOSTAT AND VOID YOUR WARRANTY. CAUTION: DO NOT SWITCH SYSTEM TO COOL IF THE TEMPERATURE IS BELOW 50°F (10°C). THIS CAN DAMAGE THE AIR CONDITIONING SYSTEM AND CAUSE PERSONAL INJURY. 1. Place the HEAT-OFF-COOL switch into the COOL position. The display will read COOL. 2.

7. Put the -ON-AUTO switch into the ON position. The blower fan should turn on. The display will show a 8. Put the and ON. -ON-AUTO switch into the AUTO position. The blower fan should turn off. Step 4: Customizing the Thermostat ◆ Settings System Cool: The thermostat controls the cooling. Off: The heating and cooling systems are off. Heat: The thermostat controls the heat. Fan Auto: Equipment controls the fan. On: The fan operates continuously.

◆ Temperature Differential The temperature differential is factory set at 1.0°F (.5°C). This means that whenever the room temperature changes by one degree Fahrenheit from the temperature setting, the system will turn on. If the system turns on too often, increase the temperature differential. ◆ Changing Fahrenheit (°F) to Celsius (°C), and the Temperature Differential 1. The thermostat is preset to display the temperature in degrees Fahrenheit (US models) or degrees Celsius (Canadian models).

Step 5: Troubleshooting Symptom Remedy Thermostat does not turn on system. Check wiring (see Installation section). Thermostat turns system on and off too frequently. Increase temperature differential (see Changing the Temperature Differential section). Display is blank, flashing or constant LOW BATT. Replace batteries. System fan does not operate properly. Move fan option switch to either gas or electric, to match system (see Installation section).
