Press HOLD to change to the next menu item or press TIME to
go backwards to the previous item in the menu. To exit the menu
and return to the program operation, press RUN. If no keys are
pressed within fifteen minutes, the thermostat will revert to
normal operation.
1) Select Temporary Hold Time - The thermostat can hold
any temperature you set it to for the amount of time you
select on this option. Your choices are 0:00 to 8:00 hours in
15 minute increments. 0:00 disables the function
Example:
1. You have selected 3:00 hours for the Temporary Hold
time period.
2. With the thermostat set to Heat or Cool, press HOLD for
approximately five seconds until HOLD time (3:00
indicating 3 hours) appears as a setting reminder.
3. After releasing the button, "HOLD" on the display will
blink.
4. Use (_ or (_ to set the temperature to your prefer-
ence. The thermostat will maintain this temperature
setting for 3 hours with "HOLD" blinking to remind you it
is in Temporary Hold. After 3 hours the thermostat will go
back to the program temperature and "HOLD" will no
longer blink or display.
2) Select FA or SL (Fast or Slow) Heating Cycle Rate - The
FAsetting isfrequently used for gas, oil or electric heat. The
SL setting produces a longer heating cycle which is nor-
mally for hot water or steam (hydronic) systems. Both
settings produce very accurate temperature control and
can be set to your personal preference. FA cycles the
system just under I°F and the SL setting cycles at approxi-
mately 1.5°F.
3) Select backlit display- The display backlight improves
display contrast in low lighting conditions. Selecting back-
light ON will keep the light on for a short period of time after
any key is pressed. Selecting OFF will keep the light off.
