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.
