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

If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermo-
stat by removing the wires from terminals R R R R R and C C C C C and removing batteries for 2 minutes. After resetting the thermostat,
replace the wires and batteries. If the thermostat has been reset and still does not function correctly, contact your heating/
cooling service person or place of purchase.

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.
