Thermostat Quick Reference

 

1. Indicates the current room temperature
2. Time and day of the week
3. Low Battery Indicator: Replace batteries when this indicator is shown.
4. Program Time Periods: This thermostat has 4 programmable time periods per day.
5. System Operation Indicators: ON will display when the COOL or HEAT is on. The compressor delay feature is active when flashing.
6. The hold is displayed when the thermostat program is permanently overridden.
7. Setpoint: Displays the user-selectable setpoint temperature.

Important
The low battery icon is displayed when the AA battery power is low. Whenever the thermostat detects low battery voltage from the AA batteries, the low battery icon will begin flashing on the screen for 21 days (if the batteries are not changed). If the batteries are not changed 22 days after the thermostat detects low battery voltage, the thermostat screen will only show the flashing battery icon until the buttons are pressed. If the batteries are not changed 43 days after the thermostat detects low battery voltage, the thermostat screen will only show the flashing battery icon until buttons are pressed and the set points will offset to 85°F/29°C in cooling and 55°F/13°C in heating. At this stage, set point changes can be made temporarily but, the set points will change back to defaulted values after a 4-hour period. The thermostat will continue to perform this low battery flashing, temperature offset condition until the internal voltage threshold is reached. When the thermostat’s internal voltage threshold is reached, all relays will be opened and the thermostat will become inoperable until new batteries are installed.

This will be indicated by “HOLD” flashing and will remain on this hold until the next programmed time period begins.

Permanent Hold: To enter a permanent Hold, press the Hold/Run button while “HOLD” is flashing. The word “HOLD” will remain on continuously, indicating a Permanent Hold.
