Field Programming
This feature is used for transferring configuration and program schedule from the master to the target thermostat.
All thermostats for a job can be mounted and powered up. Configure and program one thermostat. This will be the
master. The master will be used to copy the program to the rest of the thermostats.
Preparing the master to Send:
1. The master must be powered by 24 VAC.
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
CONFIG
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
CONFIG
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 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
CONFIG
switch simultaneously for 5 seconds to exit from the data transfer
mode and to return the master thermostat to the
OFF
mode.
