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 program-

Example:

med to 65° at night and 70° at 7 AM. If the building temp-

erature 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.

turning on the compressor if the heating and cooling system

the compressor from short cycling. Some newer compres-

sors already have a time delay built in and do not require
