Important Safety Information

WARNING:

• Always turn off power at the main power source by unscrewing fuse or switching circuit breaker to the off position before installing, removing, cleaning, or servicing thermostat.
• Read all of the information in this manual before installing or programming this thermostat.
• This is a 24V AC low voltage thermostat. Do not install on voltages higher than 30V AC.
• All wiring must conform to local and national building and electricalcodes and ordinances.
• Do not short (jumper) across terminals on the gas valve or at the system control to test installation. This will damage the thermostat and void the warranty.

Step 1: Replacing Existing Thermostat

1. Turn off power to heating and cooling system.
2. Remove cover of old thermostat to expose wires. (Figure 1)

3. 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.

4. Remove existing thermostat base from wall.

   Old Terminal	New Label	Description
   R, V-VR or VR-R	R	24 VAC
   Y, Y1 or M	Y1	Stage 1 Cooling/Heating Circuit
   O or R	O	Reversing Valve (Cooling Mode)
   B	B	Reversing Valve (Heating Mode)
   G or F	G	Fan Contactor Circuit
   Y2	Y2	2nd Stage Cooling Circuit
   W1 or W2 or W-U	W2	2nd Stage Heating Circuit
   L or X	L	System Monitor LED
   E	E	Emergency Heating Circuit
   C, X or B	C	24 VAC Transformer Common Side

   NOTE: THIS THERMOSTAT REQUIRES A 24V AC COMMON WIRE FOR PROPER OPERATION.

5. After labeling wires, remove wires from terminals.

6. Remove existing thermostat base from wall.

7. 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 tech- nical support at 1-800-445-8299.

Step 2: Installing Model 9620 Thermostat

NOTE: FOR NEW INSTALLATIONS, MOUNT THERMOSTAT ON INSIDE WALL, 4-5 FEET ABOVE THE FLOOR. DO NOT INSTALL BEHIND A DOOR, IN A CORNER, NEAR AIR VENTS, IN DIRECT SUNLIGHT, OR NEAR ANY HEAT OR STEAM GENERATING FIX- TURES. INSTALLATION AT THESE PLACES WILL AFFECT THERMOSTAT OPERATION.

IMPORTANT: THIS THERMOSTAT IS COMPATIBLE WITH 100% LOCKOUT SYSTEMS. TO RESET THE SYSTEM, TURN THERMOSTAT TO OFF POSITION FOR AT LEAST 60 SECONDS.

1. Turn off power to the heating and cooling systems.
2. Place COOL-OFF-HEAT-EM in OFF position.

3. Place AUTO-ON switch into AUTO position.

4. Remove the cover using a coin or screwdriver (Figure 2).

5. Place thermostat against the wall at desired location. Make sure wires will feed through opening on base of thermostat.

6. Mark placement of mounting holes (Figure 3). Set base aside.

7. Drill the marked holes using a 3/16" drill bit. NOTE: Enclosed plastic anchors do not require a drilled hole for drywall.

8. Tap plastic anchors into the holes.

9. Align base with plastic anchors and feed wires through opening (Figure 3).

10.  Secure base to wall with supplied screws.

11. Terminal screws are loosened. Insert wires into terminal strip (Figure 4) matching the label to the corresponding terminal (see Wiring Diagrams below). Tighten screws.

    TERMINAL LEGEND - 9620
    TERM	EQUIPMENT TO CONNECT	REQ?	TERMINAL FUNCTION
    C	24VAC common connection	Yes	For input of 24VAC common side of transformer
    L	System fault indicator connection	No	For connection of system fault indicator (if present)
    R	24VAC hot connection	Yes	For input of 24VAC hot side of transformer
    Y2	Second stage cooling connection	No	Energizes on a call for second stage cooling
    Y1	First stage compressor connection	Yes	Energizes on a call for first stage heating or cooling
    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 second stage of heat (auxiliary heat)
    O	Cool active reversing	Yes**	Energizes when in the in
    	valve connection		COOL mode
    B	Heat active reversing	Yes**	Energizes when in the
    	valve connection		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 OR a heat active reversing valve.  Use the appropriate terminal.

12. Replace cover on thermostat by snapping into place.

13. Turn on power to system. Test thermostat as described in the following section.
