Congratulations!
Your new thermostat will provide years of reliable service.

its first season of use. Thank you for buying our product!
Please read this manual for complete instructions on
installing and operating your thermostat. If you require
further assistance, please feel free to contact us.
IMPORTANT INFORMATION
1. This thermostat is designed to work on the following
systems:
• Gas – Standing Pilot • Oil – Fired Furnace
• Gas – Electronic Ignition • Single Stage Heat Pumps –
with no auxiliary heat
• Gas – Fired Boilers • Electric Air Conditioning
• Gas – Millivolt Systems • Electric Furnace
• Oil – Fired Boilers
This thermostat will NOT control multi-stage heat pumps
or 110/220V baseboard electric heating systems.
2. Temperature Range
This thermostat can be programmed between 45°F and 95°F
(7°C and 35°C). However, it will display room temperatures
from 30°F to 99°F (0°C and 37°C). HI will be displayed if
the temperature is higher than 99°F (37°C), and LO will be
displayed if the temperature is lower than 30°F (0°C).
This thermostat will automatically shut down in Heat
mode if the temperature rises above 95°F (35°C), and will
automatically shut down in Cool mode if the temperature
drops below 45°F (7°C).
3. Compressor Protection
After shutting off the cooling system, this thermostat has
a 4 minute delay before it can be restarted. This feature
will prevent damage to your compressor caused by rapid
cycling. It does not prevent a rapid compressor restart due
to short power outages.
4. Battery Warning
Two fresh AA alkaline batteries should provide over one
year of service. When the batteries need to be replaced.
The low battery indicator will flash on the display. When
you see this message, install new alkaline batteries. You
have approximately 1 minute to change the batteries and
keep the thermostat's clock and program settings. Once
the batteries have become too low to ensure proper
operation, your system will be turned off, and the display
will be cleared except for flashing Low Battery Indicator on
the LCD display.
CAUTION: When only the Low Battery icon
flashes on the display, the thermostat is shut
down, and your system will no longer operate.
In this condition, there is no temperature control.
NOTE: The backlight will not function when the thermostat
is in low battery condition.
NOTE: If you plan to be away from the premises over 30
days, we recommend that you replace the old batteries
with new alkaline batteries prior to leaving.
