OPERATION
The system "mode" is selected by pressing the SYSTEM button. Icons on the bottom right corner of the display will indicate the mode: COOL
To operate properly in the AUTO mode, the heat setpoint temperature cannot be the same as or higher than the cool setpoint temperature. The heat setpoint must be at least 1° lower than the cool setpoint.
Automatic System Changeover
When the thermostat is in the AUTO mode, both the Flame and Snowflake icons are displayed. The thermostat will call for heat or cool depending on the room temperature. The setpoint temperature displayed will be that of the last mode called. If the last system cycle was heat, the HEAT setpoint will be displayed. If the room temperature raises above the HEAT setpoint and the COOL setpoint and a call for cool is required, the temperature displayed will change to be the COOL setpoint.
Second Stage Time Delay
Your thermostat is designed to determine the optimum time to activate the second stage. Simply raising the temperature in heating or lowering it in cooling will not always force the thermostat to bring the second stage on quickly. There is a time delay from
EXAMPLE: For the last 2 hours the thermostat is set on 70 ° and the room temperature is 70 ° with the equipment using only the first stage of heat. Since the equipment is keeping the tempera- ture within 1° of setpoint, the thermostat will delay second stage for a longer time if you manually raise the temperature or if the room temperature quickly changes. Once the second stage comes on, it will come on sooner the next time there is a difference between the setpoint and the room temperature. The net effect of the staging program is that when the first stage is capable of making temperature the second stage will delay longer. When the thermostat calculates that first stage cannot make temperature in a reasonable time, the second stage will come on sooner. This built in function automatically optimizes the use of additional stages of heat or cool.
Manual Operation
Permanent Program Override (HOLD) - With the SYSTEM button set to HEAT or COOL, press the HOLD button once and release. "HOLD" will be displayed. Use (_ or (_ to adjust the temperature. The thermostat will hold the room temperature at the selected setting until you press RUN button to start program operation again.
Temperature Program Override - Press (E) or (_ until the display shows the temperature you want. The thermostat will override current programming and keep the room temperature at the selected temperature for a programmed time period. "HOLD" will be displayed and flashing. The thermostat will automatically revert to the program after programmed period.
