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, press HOLD for ap-
proximately five seconds until HOLD time (3:00 indi-
cating 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
FA setting is frequently 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 1°F and the SL setting cycles at approxi-
mately 1.5°F.
3) Select Display Light ON or OFF - The display backlight
improves display contrast in low lighting conditions. Select-
ing d-l ON will keep the light on for a short period of time
after any key is pressed. Selecting d-l OFF will keep the
light off.
