IN THIS EXAMPLE, WE WANT TO CHANGE THE “MAX HEAT ADJUST”
TO –15%. FIRST, ENTER THE SETUP MENU AS DESCRIBED IN
“ENTERING THE FURNACE MAIN MENU”
PRESS THE UP OR DOWN ARROW KEY UNTIL THE
TEXT “MAX HEAT ADJUST” IS DISPLAYED .
THE TEXT “0” IS DISPLAYED IN THE UPPER LEFT-HAND
CORNER OF THE THERMOSTAT. PRESS THE LEFT OR RIGHT
ARROW KEY A UNTIL THE TEXT “–15” IS DISPLAYED
IN THE CORNER .
PRESS THE UP OR DOWN ARROW KEY OR THE “MENU” KEY
TO SET THE VALUE. IF THE “MENU” KEY IS PRESSED,
THE PREVIOUS MENU SCREEN WILL BE SHOWN – BUT,
THE NEW VALUE (–15) WILL BE SET.
AFTER ENTERING THE “SETUP” MENU OF THE
FURNACE (SEE STEP 7 IN FIGURE 66), THERE WILL BE
SEVERAL VALUES THAT CAN BE CHANGED BY
THE INSTALLER (BASED ON NEEDS OF THE
INSTALLATION). THESE VALUES CAN BE CHANGED
TO THE DESIRED SETTING BY PRES
SING THE
LEFT OR RIGHT ARROW KEYS UNTIL THE DESIRED
VALUE IS DISPLAYED AND THEN PRESSING EITHER
THE UP OR DOWN ARROW KEY OR THE “MENU”
KEY. AN EXAMPLE FOLLOWS:
