Replacing Existing Thermostat

• Turn off power to heating and cooling system.
• Remove cover of old thermostat to expose wires. 
• Disconnect wires one at a time from existing terminals. use enclosed labels to mark existing wires. Refer to cross references in
• Table 1 if existing wiring does not directly match the labels.
• If you have any questions about cross referencing the old terminal to the new label, reference your equipment installation manual, a licensed contractor, or call Robertshaw Tech Support (800) 445-8299.
• Remove existing thermostat base from wall
• After labeling wires, remove wires from terminals.
• Remove existing thermostat base from wall.
• Refer to the following section for instructions on how to install thermostat

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.

Installing Model 9620 Thermostat

• Turn off power to the heating and cooling systems.
• Place COOL-OFF-HEAT-EM in OFF position
• Place AUTO-ON switch into AUTO position.
• Remove the cover using a coin or screwdriver 
• Place thermostat against the wall at desired location. Make sure wires will feed through opening on base of 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 holes.
• Align base with plastic anchors and feed wires through opening (Figure 3).
• Secure base to wall with supplied screws.
• Terminal screws are loosened. Insert wires into terminal strip (Figure 4) matching the label to the corresponding terminal (see Wiring Diagrams below). Tighten screws
• stall two AA ENERGIZER® brand batteries or equivalent into battery compartment. Be sure to match positive (+) ends of batteries with  positive (+) battery terminals in the battery compartment.
• Replace cover on thermostat by snapping into place.
• Turn on power to system. Test thermostat as described in the following section.

TERMINALLEGEND – 9620
TERM	EQUIPMENT TOCONNECT	REQ?	TERMINALFUNCTION

E	Emergency heat connection	No*	Energizes on a call for heat in the EM mode only
G	Indoor fan connection	Yes	Energizes with E, Y1, Y2 and W2 terminals or with FAN option switched to the ON position
W2	Second stage heat connection	No*	Energizes on a call for sec- ond stage of heat (auxiliary heat)
O	Cool active reversing valve connection	Yes**	Energizes when in the in COOL mode
B	Heat active reversing valve connection	Yes**	Energizes when in the HEAT or EM modes
* For systems using a backup heat source. If separate E terminal connection is not available, jumper E and W2. ** Most heat pump systems will have a cool active ORa heat active reversing valve. Use the appropriate terminal.

WIRING

Testing the Thermostat

• Place the COOL-OFF-HEAT-EM switch into the COOL position
• Press the button until the temperature setting is at least 3 degrees below the room temperature. The air conditioning system should turn on within a few seconds.
• Put the COOL-OFF-HEAT-EM switch into the OFF position.
• The air conditioning system should turn off. The fan may continue to run for a short period of time.
• Put the COOL-OFF-HEAT-EM switch into the HEAT position.
• Press the button until the temperature setting is at least 3 degrees above room temperature. The heating system should turn on.
• The fan may not turn on immediately, depending on the fan delay built into the furnace.
• Put the COOL-OFF-HEAT-EM switch into the OFF position. The heating system should turn off. Once again, the fan may have a delay.
• Put the AUTO-ON switchto the ON position. The blower fan should turn on.
• Put the AUTO-ON switch to the AUTO position. The blower fan should turn off.

Customizing Your Thermostat

Energy Efficient Recovery (EER™)
The Energy Efficient Recovery (EER™) feature looks ahead up to 2 hours prior to the end of the setback (or set-up) period to begin monitoring performance and calculating when to turn on your system. It also determines whether the auxiliary heat or cool stages should be activated prior to setpoint time to meet your chosen setpoint temperature. The thermostat will indicate EER in the display when this program feature is active. The EER™ feature will lockout the auxiliary stages until 20 minutes prior to upcoming setpoint time to utilize the most energy efficient first stage. The auxiliary stages of heating and cooling will be available during this lock-out period to maintain the setpoint temperature should the system not be able to keep up with the heating or cooling demand.

Setting the Program

This Robertshaw thermostat is preprogrammed with the following ENERGY STAR® settings for the greatest energy savings.

Setting	Time	Heat Setpoint Temperature	Cool Setpoint Temperature
MORN	6:00 a.m.	70°F	78°F
DAY	8:00 a.m.	62°F	85°F
EVE	5:00 p.m.	70°F	78°F
NITE	10:00 p.m.	62°F	82°F

QuickSet™ Programming Mode
QuickSet™ will program all 7 days of the week with the same program

• Place COOL-OFF-HEAT-EM in COOL or HEAT position.
• Press and hold SET. Press the button.
• Release simultaneously.
• The MORN indicator should be blinking.
• Program the time of day and the temperature as outlined in the Setting Daily Program section

Setting Daily Programming

• Place COOL-OFF-HEAT-EM in COOL position.
• Press SET button. The display will show a number from 1 to 7.
• This number represents the day of the week to be programmed.
• If programming individual days, press either button to adjust the day of the week to program.
• Press SET. Press to change MORN time.
• Press SET
• Press to change MORN temperature.
• Repeat steps 2-5 for DAY, EVE, and NITE.
• Repeat steps 2-6 above to program any other day of the week.
• Shift COOL-OFF-HEAT-EM to HEAT position.
• Repeat steps 2-6 to program HEAT (winter) settings

Begin Programmed Operation

• Place AUTO-ON into AUTO
• Place COOL-OFF-HEAT-EM into COOL or HEAT, depending on the season.
• Press PROG/MAN button until indicator is in PROG position.

Temporary Program Override

• To temporarily increase or decrease temperature
• The thermostat will automatically return to the program at the next scheduled setting change or after four hours.

Manual Operation
Press PROG/MAN until indicator is in MAN position

Reset
To reset the thermostat to factory preprogrammed conditions, press the RESET button located beneath the lower left corner of the display.

LED Indicators
The LED indicators are used to indicate system activity. The AUX indicator illuminates during a call for second stage heating. The auxiliary stages are used to maintain comfort during extremes in weather conditions. If the AUX LED is illuminated too frequently during periods of moderate temperature, check the differential settings (page 8). The CHECK indicator is used to monitor system status. If the CHECK indicator is illuminated, call your local HVAC service provider. The EMER indicator is illuminated only when the system switch is moved to the EM (emergency heat) position. The EM position is used only when the primary stage of heat is not functioning or requires service.
