Installing and Changing Batteries
For Battery Thermostat Operation
If your LCD is blank, or displaying LO BAT, the batteries are not installed or
need to be changed. We suggest you change the batteries at least once a year,
or whenever the LO BAT warning displays.
Remove the cover, and install the two "AAA" alkaline batteries into the battery
compartment. Proper battery installation is important! Make sure the positive
ends of the batteries match the positive terminals in the battery compartment.
For Hardwired Thermostat Operation
Batteries are not required when a common wire is connected to the C terminal of the SC2010 N/L
thermostat.

This feature is used for transferring the configuration settings from the master to the target
thermostat. All thermostats for a job can be mounted and powered up. Configure one thermostat. This
will be the master. The master will be used to copy the configuration to the rest of the thermostats.
Preparing the master to Send:
1. The master must be powered by 24 VAC or batteries.
2. Verify the master thermostat is in OFF mode. Slide system switch to center
position.
3. Remove cover of the master thermostat by gently pulling near one of the corners
at the top of the thermostat.
4. Press the up and down buttons and RIGHT switch simultaneously for 5
seconds.
5. The OUT screen displays indicating the master thermostat is ready to
transfer data.
Note: Press the up and down buttons and RIGHT switch simultaneously for
5 seconds to exit from data transfer mode and to return the master to
the OFF mode.
6. Connect the master to the target using the 3 wire connector. Attach one end to
the Master's FP pins and the other end to the Target's FP pins.
Note: Target thermostat must be powered by 24 VAC or batteries for field programming to
occur.
When the connection has been made correctly, the master thermostat will power up and the target will
count from 6 down to 1. It will then display LOC confirming the data has been saved in memory.
When all target thermostats have been completed, reinstall the master thermostat.
Press the up and down buttons and the RIGHT switch simultaneously for 5 seconds to exit from the
data transfer mode and to return the master thermostat to the OFF mode.
