SYSTEM CONFIGURATION
ENERGY MANAGEMENT RECOVERY
(EMR)
When the EMR feature is activated, the thermostat's
microcomputer automatically calculates the time it will
take to change the temperature to the next program
setting. Then the thermostat will activate the heating
system to change the temperature so that the desired
temperature is reached at or near the beginning of the
next program period (the thermostat's microcomputer
calculates 15 minutes for every 2 F temperature change).
For example, assume that the thermostat is programmed
to provide an overnight heating temperature of 62 F, and
during the next program period, programmed to begin at
6:00 AM, the programmed temperature is 70 F. With
EMR activated, the thermostat will automatically activate
the heating system at 5:00 AM, so that the programmed
temperature of 70 F is reached by about 6:00 AM.
The thermostat is shipped with the EMR feature inactive,
which means that the thermostat will activate the heating
or cooling system at, not before, the beginning of the
program period (real time).
To activate the EMR function, clip wire S3 on the back
of the thermostat (see fig. 8).
CHECK THERMOSTAT OPERATION
If at any time during testing the system does not function
correctly, disconnect electrical power at fuse box or circuit
breaker and check that all wiring is correct.
