After a power loss, the remote sensors will be operating properly, however, temperature at the remote sensors can not be displayed until PROGRAM RUN is pressed.

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 0-30 minutes depending on the performance of the first stage of the system.

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 temperature within 1 degree of setpoint, the thermostat will delay second stage for a longer time if you manually raise the temperature or if the room tempera- ture 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. Should your needs require a modification of the factory default settings, refer to “Heat Fast” or “Cool Fast” instructions on page 31.
