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 electrical

codes 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.

local waste management authority for instructions regarding proper dis-

posal 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. DONOT 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. TORESET THE SYSTEM, TURN

appropriate terminal.

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: DONOT 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 COOL-OFF-HEAT-EM

switch into the COOL position

2. 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.

5. 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.

6. 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.

7. Put the AUTO-ON switch

to the ON position. The blower

fan should turn on.

8. Put the AUTO-ON switch

to the AUTO position. The blower

fan should turn off.

Release simultaneously.

Press or to change time of day.

2. Press Press

to change day of week.

3. Press Press

to change 1st stage

temperature differential.

NOTE: THE TEMPERATURE DIFFERENTIAL IS FACTORY PRESET AT 1°. THIS MEANS THAT

WHENEVER THE ROOM TEMPERATURE CHANGES BY ONE FULL DEGREE FROM THE TEMPERA-

TURE SETTING, THE SYSTEM WILL TURN ON. IFTHE SYSTEM TURNS ON TOO OFTEN,

INCREASE THE TEMPERATURE DIFFERENTIAL.

4. Press Press

to change 2nd stage

temperature differential.

NOTE: THE SECOND STAGE TEMPERATURE DIFFERENTIAL IS FACTORY PRESET AT 2°.

5. Press Press

to change

residual cooling.

NOTE: THE RESIDUAL COOL FEATURE WILL KEEP THE SYSTEM FAN ON FOR AN

ADDITIONAL 30, 60, OR 90 SECONDS AFTER THE COMPRESSOR CYCLES OFF IN COOL

◆Changing Fahrenheit (F) to Celsius (C)

Press and hold SET. Press

Release both simultaneously.

◆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 per-

formance and calculating when to turn on your system. It also determines

whether the auxiliary heat or cool stages should be activated prior to set-

point 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.

Step 5: Setting the Program

This Robertshaw thermostat is preprogrammed with the following

ENERGY STAR®settings for the greatest energy savings.

Setting Time Heat Setpoint Cool Setpoint

Temperature 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

These settings can be customized using the following QuickSet™ or daily

programming guides.
