The flashing or flickering flame indicates that the thermostat is calling for heat. Only on two stage thermostats, if you have a number 2 or two flames then the system is looking to turn on a second stage of heating to help the first stage. This would be due to the fact that the system is calling for more than three degrees or the first stage hasn't been able to raise the temperature by itself.

The flashing snowflake indicates that the thermostat is calling for cooling. Only on two stage thermostats, if you have a number 2 or two snowflakes then the system is looking to turn on a second stage of cooling to help the first stage. This would be due to the fact that the system is calling for more than three degrees or the first stage hasn't been able to lower the temperature by itself.

There is nothing in the thermostat to cause a beep. Perhaps a smoke or CO alarm placed nearby is beeping?

EER stands for Energy Efficient Recovery if your thermostat can control up to 2 stages of heating and cooling.  In the program mode, EER looks ahead up to two hours before the end of the current set-back or setup temperature period and decides if it is necessary to activate the first stage of heating or cooling to meet the next temperature set point.  EER is designed to activate only the most economical stage of heating or cooling up to 30 minutes before the next temperature change when it decides if an auxillary stage is needed to help meet that temperature.  It is a feature designed to save you money.

There is a RESET button inside the thermostat that when pressed will remove "LO BAT" from the display and bring it back to normal.  First place the thermostat to OFF then remove the cover and look for a small round push button with a square silver base.  Press the button and the display will return to normal.
 If you cannot locate the reset button remove the batteries for 15 minutes to reset.

Begin by pressing and holding both the down and up buttons for a few seconds.  The temperature differential for stage one will appear in the display.  Release both buttons.  Press either the down or up button to select the preferred setting of 1, 2, or 3. If you have a 2 stage thermostat (models 9515 or 9520)  wait for approximately 5 seconds and the temperature differential for stage two will begin flashing in the display.  Press either the down or up button to select the preferred setting of 2, 3, 4, 5, or 6.  Wait approximately 5 more seconds for the display to return to normal.

When in the heating or cooling mode press the up or down arrow keys and the display will say SET and show a temperature.  Press the up or down arrow keys to raise or lower the temperature to your desired setting.  After 5 seconds of inactivity the display will go back to the room temperature.

This model thermostat has continuously self-calibrating circuit.  A precision .5% tolerance reference resistor is used to re-calibrate the circuit once every minute.

The flashing or flickering flame indicates that the thermostat is calling for heat. Only on two stage thermostats, if you have a number 2 or two flames then the system is looking to turn on a second stage of heating to help the first stage. This would be due to the fact that the system is calling for more than three degrees or the first stage hasn't been able to raise the temperature by itself.

There is nothing in the thermostat to cause a beep. Perhaps a smoke or CO alarm placed nearby is beeping?

All Robertshaw digital thermostats utilize an electronic temperature sensor and circuitry to control the HVAC system. They are completely mercury free.

Make sure there is nothing environmental causing the thermostat to read incorrectly. Check for things such as: 1)The unit is in the path of the exhaust of a fan cooled device. 2)The wall that the unit is located on is being indirectly heated by a device on the other side such as a television, lamp, or other heat-generating electrical device.

Begin by pressing and holding the SET button.  Next press and hold the PROG/MAN button.  Release both buttons.  The current time of day will appear on the display.  Set the clock to the correct time by pressing either the down or up buttons.  The time will adjust by minutes.  When the correct time is set press and release the SET button.  The day of the week will be displayed.  Press either the down or up buttons to display the correct day of the week.  1=Monday and so on to 7=Sunday.  Press and release the SET button.  The differential setting will be displayed.  Press either the down or up buttons to select the preferred setting of 1, 2, or 3 degrees. If you have a 9615 or 9620 press the set button to get to the second stage differential which is adjustable from 2-6 degrees.  Press and release the SET button or wait 45 seconds and the display will return to its normal mode.

 

 

 

This model thermostat has continuously self-calibrating circuit.  A precision .5% tolerance reference resistor is used to re-calibrate the circuit once every minute.

Press and hold the SET button.  While holding the Set button press and hold the down arrow button.  Release both buttons simultaneously and the temperature scale should switch between F and C.

 

All Robertshaw digital thermostats utilize an electronic temperature sensor and circuitry to control the HVAC system. They are completely mercury free.

Make sure there is nothing environmental causing the thermostat to read incorrectly. Check for things such as: 1)The unit is in the path of the exhaust of a fan cooled device. 2)The wall that the unit is located on is being indirectly heated by a device on the other side such as a television, lamp, or other heat-generating electrical device. Clean the thermostat: Using the brush attachment on a vacuum cleaner, vacuum the outside edges of the thermostat to remove any dust that may have collected on the temperature sensor. If the problem is not being caused by any of the conditions described above, reset the thermostat. If this does not work, replace the thermostat.

No it will only work on the 9700 series thermostats not the i-series. The correct indoor sensor for the i-series and i2-series thermostats is 9020i.

Press and hold in the SET button, press the FILTER button and release both simultaneously. You wll see a 3 digit number for the number of hours for the filter monitor. It is adjustable from 0-960 hours in 60 hour increments with the arrows. When you are finished press SET to exit.

Press and hold the SET button.  While holding the SET button press and hold the FILTER button.  Release both buttons together.  Press the down or up buttons to change the displayed number of hours of system "run time" you would like the CHECK FILTER reminder to reappear.  Press the SET button to save the setting and to return to normal display mode.  CHECK FILTER will be removed from the display.

The thermostat can be unlocked by pressing the RESET button on the back of the faceplate.  It is a round hole on the bottom right of the thermostat.  Insert the tip of a pencil or ballpoint pen to depress the button located in this hole.  This will reset the thermostat and delete the lock code.  If you do not want to use the lock feature turn off  the dipswitch  for the lock on switch 2 and press the RESET button. 

Note:  If you press the reset button you will lose all other programming.

EER stands for Energy Efficient Recovery if your thermostat can control up to 2 stages of heating and cooling.  In the program mode, EER looks ahead up to two hours before the end of the current set-back or setup temperature period and decides if it is necessary to activate the first stage of heating or cooling to meet the next temperature set point.  EER is designed to activate only the most economical stage of heating or cooling up to 30 minutes before the next temperature change when it decides if an auxillary stage is needed to help meet that temperature.  It is a feature designed to save you money.

 

 

 

The thermostat can be programmed to allow the indoor fan to continue running after the temperature setting has been satisfied and the air conditioning compressor has shut down.  It can be programmed to run in 30 second increments for up to 90 seconds.  This allows the fan to deliver the cooled air that remains in the ductwork after the compressor has shut off.

When the thermostat loses voltage a supercapacitor in the faceplate will keep the volatile memory active for approximately 20 minutes while displaying AC.  This is an indicator that the HVAC unit has lost power and may need to be serviced by a qualified technician.
