If Run Time is chosen, the service reminder will be set in hours. After the HVAC system has been  
operating for the selected number of hours, a Service Reminder will be displayed informing you that  
service is suggested for your system.  
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.

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.  
The last unique feature is the OFFSET or calibration feature. This 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.

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 opti-  
mal 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.

from improper installation, alteration, misuse or abuse of the thermostat occurring after the date of pur-  
chase.  
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 thermo-  
stat 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 war-  
ranty 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 recom-  
mendations 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 dura-  
tion of this warranty.  
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.  
Some states do not allow the exclusion or limitation of incidental or consequential damages, or allow limi-  
tations 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.
