Personal Program Schedule
Use the following personal program schedule to record your settings
SimpleSet 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:
- The master must be powered with 2 "AAA" batteries.
- Verify the master thermostat is in OFF mode. Slide system switch to center position.
- Remove cover of the master thermostat by gently pulling near one of the corners at the top of the thermostat.
- Press the UP and DOWN buttons and CONFIG switch simultaneously for 5 seconds.
- 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.
![]()
- 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 with 2 "AAA" 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 5 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.
Troubleshooting
Symptom | Remedy |
No display | Check batteries; display is blank when batteries are not present or are dead |
System fan does not come on properly | Verify wiring is correct, check Gas/Electric jumper position |
Program schedule activates at the wrong time | Check time (AM/PM) set on thermostat (see "Setting the Time,") |
Thermostat turns on and off too frequently | Adjust temperature differential (see "Configuration Mode Settings,") |
Thermostat does not follow program | Verify it is operating in Program mode (PROG displays); check time (AM/PM); check if in 2-hour Hold mode |
Fan runs continuously | Check Fan Auto/On switch, continuous fan operation in ON position |
on display | Batteries need to be replaced |
Problem not listed above | Press reset button once* |
