Your new thermostat will provide years of reliable service. Using this  digital thermostat will provide more uniform comfort in your home through 

the seasons. Thank you for buying the 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: 

Ÿ

 Gas – Standing Pilot 

Ÿ

 Oil – Fired Furnace 

Ÿ

 Gas – Electronic Ignition 

Ÿ

 Single Stage Heat Pumps – with no 

Ÿ

 Gas – Fired Boilers 

auxiliary heat 

Ÿ

 Gas – Milivolt Systems 

Ÿ

 Electric Furnace 

Ÿ

 Oil – Fired Boilers 

Ÿ

 Electric Air Conditioning 

This thermostat will NOT control multistage heat pumps or 110/220V baseboard electric heating systems.

 

2. Temperature Range

 

This thermostat can be set 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 cutoff in Heat mode if the temperature rises above 95˚F (35˚C), and automatically cutoff in Cool mode if the temperature drops below 

45˚F (7˚C).

 

3. Compressor Protection

 

This thermostat provides a 4 minute delay after shutting off the compressor 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 well over one year of service. However, when the batteries become drained the Low Battery Indicator will flash on the 

display. When this message occurs, install new alkaline batteries. You have approximately 1 minute to change the batteries and keep the thermostat’s 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  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 of your dwelling.

 

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.
