Example:
You select EMR and have your heating programmed to 65° at night and 70° at 7 AM. If the building temperature is 65° the
difference between 65° and 70° is 5°. Allowing 5 minutes per degree the thermostat set-point will change to 70° at 6:35 AM.
Vice versa for Cooling.
Always turn off power at the main power source by removing the fuse, or switching the circuit breaker to the off position before
installing, removing, cleaning, or servicing this thermostat.
Use this thermostat only as described in this manual. Read all of the information in this manual before installing this thermostat.
Use a professional personnel / installer to install this thermostat.
This is a 24VAC low-voltage thermostat, do not install on voltages higher than 30 vac.
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.
Do not switch the system to cool if the temperature is below 50ºF (10ºC). This may damage the air conditioning system.
Replace batteries when the battery icon indicates the low battery message.
Change the Air Filter when the Filter Change Icon begins blinking.
This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the
following guidelines in mind when planning your program:
When heating (cooling) your building, program the temperatures to be cooler (warmer) when the building is vacant or during
periods of low activity.
During early morning hours, the need for cooling is usually minimal.
The time of day clock must be set correctly in order for the programmed periods to be correct
Look at the factory pre-programmed times and temperatures shown in the example schedule. If this program as below will suit your
needs, simply press the
RUN
button to begin running the factory preset program.
Factory Pre-Programmed Example:
If you want to change the pre-programmed times and temperatures, follow these steps.
Determine the time periods and temperatures for your weekday and weekend programs. You must program 4 periods for both the
weekday and weekend program. However, you may use the same heating and cooling temperatures for consecutive time periods. You
can choose start times, heating temperatures, and cooling temperatures independently for both weekday and weekend programs (for
example, you may select 5:00 AM and 70° as the weekday
1st period heating
start time and temperature, and also choose 7:00 AM
and 76° as the weekday
1st period cooling
start time and temperature).
Use the table below to plan your program time periods and the temperatures you want during each period. Fill in the completed table
to have a record of your program.
