6. Holding Temperature
The HOLD MENU, located in the MAIN MENU, allows you to hold a temperature until a set date and time,
as would be done during a holiday, or allows you to hold a temperature permanently.
6.1 Holiday Hold
You can program the thermostat to hold a temperature for a period of time. Whether you want to hold a temperature for a
few hours or for a few weeks, your thermostat can accommodate your schedule. First the thermostat will prompt you for a
temperature to hold. If you are in AUTO MODE you will be prompted for both a heat setting and a cool setting. Next it will
prompt you for a date and time that you wish to return to programmed operation. On the Main Screen, the INFO button
will change to RESUME PROG. If you choose to cancel the hold, simply press this button and the program will resume.
You must be in HEAT, COOL or AUTO mode to program a hold; the thermostat will inform you of this if you attempt to
HOLD while in the OFF mode.
