Option 99 — Reset to Factory Defaults
Use this capability to reset the Thermidistat Control to “out of the box” conditions.
BEWARE! All configuration settings, program settings, clock, and calendar which
have been manually entered will be lost!
When this option is selected, the configuration number (99), will appear on the left
and 10 will appear on the right. To perform the reset, first use the MODE key to
move the box from the 99 to the 10 (programmable model) or to flash the 10
(non--programmable model). Then press and hold the DOWN key. The 10 will start
counting down toward zero. If the DOWN key is kept pressed until the count
reaches zero, the reset will be performed. When the value reaches zero, the heat
setpoint shall display ----. The cool setpoint shall display -- and the room air
temperature shall display Fd. When the factory defaults have been restored, the
Thermidistat Control will act as if power was cycled and return to normal operation.
If the DOWN key is released early, the number will return to 10 and the reset will
not occur.
