Always turn off power at the main power source by unscrewing fuse or switching circuit
breaker to the off position before installing, removing, or cleaning this thermostat.
Read all of the information in this manual before 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.
This thermostat is equipped with automatic compressor protection to prevent potential
damage due to short cycling or extended power outages. The short cycle protection provides a
5-minute delay between heating or cooling cycles to prevent the compressor from being damaged.
Do not switch system to cool if the temperature is below 50°F (10°C). This can damage the
cooling system and may cause personal injury.
Use this thermostat only as described in this manual.

Events
An event is a programming period. This could be the period in the morning when the facility is occupied. It could be the period when
no one is at work. It could be the evening.
The time for an event is selected based on when you want the event to occur. For example, if people start to arrive at the facility at
6:30 AM, set the first event for 6:30 AM. The thermostat will automatically make sure the environment is at the desired temperature
selected for that event by the time you desired.
This thermostat can be selected for 2, 4, or 6 events.
Energy Saving Programs
The thermostat is set with the US EPA ENERGYSTAR®recommended times and temperatures for optimal energy savings. You can
change these to suit your lifestyle.
The best rule is to examine your schedule and set the times and temperatures that best fit. This thermostat is so versatile, you can
easily temporarily change temperatures or programs at a whim.

The temperature differential is your comfort level. The differential is the difference from setpoint

stage differential. If the temperature falls below (or above for cooling) the setpoint by the 1ststage
differential plus the 2ndstage, the auxiliary heating (or cooling) system will turn on.
The 2ndstage delay is a timed delay before the second stage will turn on if the setpoint has not
been achieved within that time frame.

If Calendar Time is chosen, the service reminders will be set in days. After the selected number of
days has passed, a Service Reminder will be displayed informing you that service is suggested for

TEMPERATURE OFFSET
The OFFSET or calibration feature allows the installer to recalibrate the thermostat if the displayed
room temperature is not the actual room temperature. The OFFSET feature also allows you to display a temperature that is different from the actual room temperature.
SHORT CYCLE PROTECTION
You can change or remove the timed delay that protects the compressor in an air conditioner or
heat pump system. Short Cycle Protection should be turned off ONLY if the HVAC system has other
protective circuits that guarantee a compressor off time. This feature is adjustable from OFF to 5
minutes in 1-minute increments.
Changing INSTALLER SETTINGS
The INSTALLER SETTINGS are selected based on the type of equipment you have in your facility. This feature should be set only by
a certified HVAC technician. Changing these settings could result in higher energy costs and may even damage the equipment. You
should only change the FILTER MONITOR length should you get a new type of filter.
Energy Efficient Recovery™ (EER™)
Energy Efficient Recovery™ is an energy saving feature. During a set back period (or set up in cooling), it allows the thermostat to
look up to two hours ahead to determine when to turn on the heating (cooling) system. During this time period, the second stage is
locked out to allow the first (and most efficient stage) to bring your facility to the desired temperature.
Indoor Sensor
The remote indoor sensor (part #9020i) can be used to improve the comfort of your home. When used in conjunction with the local
sensor on the thermostat, the two sensors average the sensed temperature and control to that average temperature.
You also can use the remote sensor in a stand-alone situation when you want to control the temperature in a remote area but have the
thermostat in a secure location.
Outdoor Sensor
The remote outdoor sensor (part #9025i) can be used to aid in the comfort of your facility or simply as a sensing device to inquire
about outdoor conditions. In most applications, the thermostat will have a display of the temperature sensed by the remote outdoor
sensor. With a heat pump system, the remote outdoor sensor can help determine when to turn on the second stage of heating for optimal comfort. The remote outdoor sensor should be installed on the northern wall of the facility, away from direct sunlight or other heat
sources that may affect its sensitivity.

Additional Information
For additional troubleshooting information, visit our web site at www.about-i-series.com. To talk with a service representative, give us a
call at 800-445-8299.
Power Outage Protection
The thermostat automatically retains the time of day for approximately two hours in the event of a power outage. All other programmed
parameters are stored permanently in memory. So, if the power is out for more than two hours, simply reset the clock. See page 4.
Resetting to Factory Conditions
To reset the thermostat to factory conditions, press the UP button and the LEFT button at the same time. Hold for 8 seconds. The time
of day will display 12:00 indicating a reset has occurred.
NOTE:This will erase all programming and return the thermostat to the factory conditions including the installer settings. Use this
only as a last resort.
TWO YEAR LIMITED WARRANTY
The manufacturer warrants to the original contractor installer or to the original consumer user, each
new Robertshaw thermostat to be free from defects in materials and workmanship under normal use and
service for a period of two (2) years from the date of purchase.
This warranty does not cover batteries (if so equipped), damage caused by batteries, damage resulting
from improper installation, alteration, misuse or abuse of the thermostat occurring after the date of
purchase.
The manufacturer agrees to repair or replace at its option any thermostat under warranty provided it is
returned within the warranty period, postage prepaid, with proof of the date of purchase. Cost of thermostat removal or reinstallation is not the responsibility of the manufacturer.
Repair or replacement as provided under this warranty is the exclusive remedy of the consumer. This
warranty and our liability does not apply to merchandise that has been damaged caused by misuse,
neglect, mishandling, alterations, improper installation, or use in a way other than in accordance with the
recommendations and instructions of the manufacturer. Except to the extent prohibited by applicable law,
any implied warranty of merchantability or fitness for a particular purpose on this product is limited to the
duration of this warranty.
Some states do not allow the exclusion or limitation of incidental or consequential damages, or allow
limitations on how long an implied warranty lasts, so the above limitations or exclusions may not apply
to you. This warranty gives you specific legal rights, and you may also have other rights which vary from
state to state.
Instructions for return:
Pack the thermostat carefully in a well-padded carton. Be sure to include a note describing, in detail,
what is wrong with the product. Return, postage prepaid, to:
