Heater Control Display

The display shows information on a 2-line, 16-character
back-lit Liquid Crystal Display (LCD). The back-light is
normally off, but it turns on for 5-minutes after power-up
and for 5-minutes after any button press. Use the LCD to
set up and monitor the operation of your heater.
If the control keys remains inactive for 5-minutes, the
screen will revert to the current view.
On a normal power-up, the control displays the current
software revision on the LCD for 2-seconds and then
resumes the user-selected mode it was in before power
was interrupted.
If unit type has not been set (like during the replacement
of the control), the control prompts the user to set the
model type (Heat Only or Heat/Cool) before any device
operation is enabled.
Upon initial installation, there are several items that
can be defined and programmed depending on the
configuration and accessories intended to be controlled
by the heater. Refer to "Program Menu" section on page
