Owners Manual

Model : CP1719

Congratulations!

Your new thermostat will provide years of reliable service. By saving energy, your

thermostat will pay for itself during its first season of use. Thanks 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:

y Gas – Standing Pilot y Oil – Fired Furnace

y Gas – Electronic Ignition y Single Stage Heat Pumps –

with no auxiliary heat

y Gas – Fired Boilers y Electric Air Conditioning

y Gas – Millivolt Systems y Electric Furnace

y Oil – Fired Boilers

This thermostat will NOT control multistage 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 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 minutes delay after shutting off the cooling system 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 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 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.
