! 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.

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: DO NOT SWITCH SYSTEM TO COOL IF THE TEMPERATURE IS BELOW 50°F (10°C). THIS CAN DAMAGE
THE AIR CONDITIONING SYSTEM AND CAUSE PERSONAL INJURY.
COOL-OFF-HEAT-EM
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.
NOTE: ONCE THE THERMOSTAT TURNS THE SYSTEM OFF WHILE IN THE COOL OR HEAT MODE, A BUILT-IN DELAY KEEPS THE COMPRESSOR FROM TURNING ON FOR ABOUT 5 MINUTES. THIS PROTECTS THE COMPRESSOR. NO ADDITIONAL TIME DELAY RELAY (DELAY ON
BREAK) IS NECESSARY. TO OVERRIDE THE 5-MINUTE DELAY FOR INSTALLATION, PRESS RESET. THIS WILL ERASE THE DELAY AS WELL
AS ALL PROGRAMMING.
COOL-OFF-HEAT-EM
3. Put the COOL-OFF-HEAT-EM switch into

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.

◆ 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.
Step 5: Setting the Program
This Robertshaw thermostat is preprogrammed with the following
ENERGY STAR® settings for the greatest energy savings.

◆ 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.
