3.3. Setting Individual Schedules
As shown in the Schedule menu (Fig. 73 on page 30), 
schedules can be set for the following time periods:
• Monday through Friday

SCHEDULING EXAMPLE
Setting the schedule is independent of the temperature 
settings for the relay outputs. The following illustrates a 
weekly schedule for daytime (setpoint) and night time 
(setback) use and shows the factory default settings:
To set a schedule, continue with “3.3.1. E1 SETPT 
(setpoint for event 1)”.
The following figures show the MON-FRI menu, but the 
menu selections are the same for any time period.

SUMMARY MENU
The Summary menu provides the ability to view the 
schedule (E1 and E2 times) for each relay for each day of 
the week.
NOTE: Scheduling must be enabled for the 
Summary menu to display. Enabling the 
schedule is determined in the Setup process 
for the Output Options (see “2.3.3.1. USE 
SCHED” on page 25).
Fig. 81. Summary Example - Monday Settings.
For each relay, the Summary display indicates the time 
and temperature (in parenthesis) for each of the two 
scheduled events E1 and E2.
1.Press the MENU button to view the menu.
2.Use the
  and  buttons to highlight 
SUMMARY.
3.Press the 
 button to display the Summary 
settings.
4.Use the 
 button to scroll forward through each 
day of the week (Monday, Tuesday, Wednesday, 
Thursday, Friday, Saturday, and Sunday).
5.While viewing a specific day, use the
  and  buttons to cycle through the individual relay 
schedules for that day.
When finished, press the home key to return to the home 
display screen.
TROUBLESHOOTING
Power Loss
The date and time settings are retained for 24 hours after 
a power outage. After a power loss of more than 24 hours, 
the date and time settings may need to be reentered. All 
other settings are stored permanently.
Errors and Diagnostics
The controller provides an error message and diagnostic 
status as described below.
Error Message
There is a two-character error code that displays in 
response to controller software problems:
EE
EEPROM Failure — The values read back from 
the EEPROM are not the same as written into the 
EEPROM. This error cannot be field repaired. Replace 
the device.
Diagnostic Messages
There are two diagnostic messages that can display in 
response to sensor problems. The diagnostic codes that 
can flash on the display are:
– –
Sensor Open or Shorted — Two dashes display
when a sensor (typically temperature) is open or 
shorted. An open circuit is considered anything 
greater than 1570 ohms (greater than 300F), shorted 
anything less than 770 ohms (less than -73F). 
Whichever stages are operating with this sensor 
cease to control (meaning relays go to OFF and 
proportional outputs go to zero percent).
This message can also mean that the sensor is 
programmed, but not physically connected.
-60° or 270° F (-51° or 132° C) Blinking
Temperature Out of Range — The temperature 
display blinks when the sensed temperature range is 
outside of the display range, below -60° F (-51° C) or 
above 270° F (132° C). The displayed value remains at 
that displayed limit and control continues. Controller 
continues to function unless an open or shorted state 
is detected.
Blinking relay status
Relay Minimum Off Time is Active — On the home 
screen, each relay’s indicator („) blinks while the 
relay’s minimum off time is active.
