Installation
Installing Model 9515 Thermostat
- Turn power off to the heating and cooling systems.
- Place COOL-OFF-HEAT in OFF position.
- Place
AUTO-ON switch into AUTO position. - Remove the cover using a coin or screwdriver (Figure 2).
- Place thermostat against the wall at desired location. Make sure wires will feed through opening on base of the thermostat.
- Mark placement of mounting holes (Figure 3). Set base aside
- Drill the marked holes using a 3/16″ drill bit. NOTE: Enclosed plastic anchors do not require a drilled hole for drywall.
- Tap plastic anchors into the wall.
- Align base with plastic anchors and feed wires through opening.
- Secure base to wall with supplied screws
- Connect wires to terminal strip (refer to wiring diagrams).
- Make sure wire connections are secure.
- Set the °F/°C switch to either °F for Fahrenheit display or °C for Celsius display readout (Figure 4).
- Set the GAS/ELEC switch to either GAS for a gas/oil heating system or ELEC for an electric heating system.
- Replace cover onto thermostat by snapping into place.
- Turn on power to system. Test thermostat as described in the following section
Operation
Setting or Changing the Setpoint Temperature
- Press either the
button. - The display will show the current temperature setpoint.
- Press either the button to adjust the temperature setting either up or down
Changing Temperature Differential
- Fahrenheit from the temperature setting, the system will turn on. If the system turns on too often, increase the temperature differential.
- Press both buttons at the same time and hold for one second.
- Press either the or button to adjust the 1st stage temperature differential up or down.
- After 5 seconds DIFF will begin to flash on the display indicating 2nd stage differential value.
- Press either the button to adjust the 2nd stage temperature differential up or down
To Test Thermostat
- Place the COOL-OFF-HEAT switch into the COOL position.
- Press the
button until the temperature setting is at least - degrees below the room temperature. The air conditioning system should turn on within a few seconds.
- NOTE: When in the COOL mode once the thermostat turns off, a built in 5- minute delay prevents the system from turning on again.
- This protects the compressor. No additional time delay relay is required. To override the 5- minute delay for installation, press the RESET button.
- Put the COOL-OFF-HEAT switch into the OFF position. The air conditioning system should turn off.
- Put the COOL-OFF-HEAT switch into the HEAT position.
- Press the
button until the temperature setting is at least - degrees above room temperature. The heating system should turn on. The fan may not turn on immediately, depending upon the fan delay built into the furnace.
- Put the COOL-OFF-HEAT switch into the OFF position. The heating system should turn off. The fan may continue to run for a short period of time.
- Put the AUTO-ON switch to the ON position. The blower fan should turn on.
- Put the AUTO-ON switch to the AUTO position. The blower fan should turn off.
Changing Fahrenheit (F) to Celsius (C)
- The thermostat is preset to display the temperature in degrees Fahrenheit.
- You may change the display readout to Celsius if desired.
- Move the manual switch marked F (Fahrenheit) and C (Celsius) located at the center of the circuit board to the desired setting (page 5).
- Press RESET button located to the right of the LCD display to register the change.
- The display will change to show the temperature in your desired temperature scale. To return the thermostat to its original setting, repeat steps 1 and 2 above.
Note: Pressing the RESET button resets the 1st and 2nd stage differential to factory preset conditions.
LED Indicator
The LED indicator illuminates during a call for second stage heating or cooling. The auxiliary stages are used to maintain comfort during extremes in weather conditions. If the LED is illuminated too frequently during periods of moderate temperature, check the differential settings (page 6).
