3. After releasing the button, "HOLD" on the display will blink.
4. Use  or  to set the temperature to your preference. 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 normally for hot water or steam (hydronic) sys-
tems. 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 approximately 1.5°F.
3. Select backlit display – The display backlight improves display contrast in low lighting conditions. Selecting
backlight ON will keep the light on for a short period of time after any key is pressed. Selecting OFF will keep the
light off.
4. Select Energy Management Recovery OFF or ON – Energy Management Recovery (EMR) causes the
thermostat to start heating or cooling early to make the building temperature reach the program setpoint at the
time you specify. Heating will start 5 minutes early for every 1° of temperature required to reach setpoint.
Example:
You select EMR and have your heating programmed to 65° at night and 70° at 7 AM. If the building temperature
is 65° the difference between 65° and 70° is 5°. Allowing 5 minutes per degree the thermostat setpoint will
change to 70° at 6:35 AM. Cooling allows more time per degree because it takes longer to reach temperature.
