Option 39 -- Display Setpoint Only or Setpoint and Room Temperature
This configuration option determines what the display on the thermostat will
look like.
Selections:
SP — Will display the setpoint only.
rt — Will display the setpoint and room air temperature
Default = SP
Option 99 -- Reset to Factory Defaults
Selection:
See below — There is no default.
Use this capability to reset the thermostat to “out of the box” conditions.
NOTE : All previous configuration settings will be lost!
When this option is selected, the configuration number (99), will appear on the
large upper display and 10 will appear on the lower. To perform the reset, first
use the MODE key to make the 10 flash. 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. If the DOWN key is
released early, the number will return to 10 and the reset will not occur.
Step 4 — Check Thermostat Operation
The PTAC Comfort Series non--programmable thermostat has a built--in installer
test capability. Use it to check thermostat and equipment operation without
delays or setpoint adjustments to force heating or cooling.
NOTE : Any time delays or protections built into the equipment will still be
active.
