Programming Mode
The Mode Selector Jumper JP3 must be set to the “PGM” mode (Programming Mode). Refer to Wiring on page 2. To
exit, set the Jumper JP3 back to the “RUN” mode (Operation Mode). All changes will be saved.
Setpoint and User Control
1. “inside temper sensor offset”
Range:
Offset
Increment:
10.0 to 40.0ºC [50.0 to 104.0ºF]
Max. ± 5ºC
0.1ºC [0.2ºF]
Compare the displayed temperature reading with a known value from a thermometer. To offset or calibrate the sensor, use the
arrows key to set the desired temperature reading. This is useful for thermostats installed in areas where the temperature read
is slightly different than the room’s actual temperature. For example, a thermostat placed right under the air diffuser. If the
thermostat is set to use an external temperature sensor, (t10.0 at Step 38), the thermostat displays "OFF".
2. “adjust minimum user setpnt”
Default:
Range:
Increment:
15.0ºC [59ºF]
10.0 to 40.0ºC [50 to 104ºF]
0.5ºC [1ºF]
In Operation mode, you cannot decrease the setpoint to less than the value that is set as the minimum user point. The
minimum value is restricted by the maximum value set at Step 3. In other words, the value that is set as the minimum cannot
be greater than the maximum value.
3. “adjust maximum user setpnt”
Default:
Range:
Increment:
30.0ºC [86ºF]
10.0 to 40.0ºC [50 to 104ºF]
0.5ºC [1ºF]
In Operation mode, you cannot increase the setpoint to more than the value that is set as the maximum user point. The
maximum value is restricted by the minimum value set at Step 2. In other words, the value that is set as the maximum cannot
be less than the minimum value.
4. “user setpnt locked”
Default:
Range:
No (Unlocked)
Yes / No
If set to No, the user setpoint option is not locked and the user can adjust the desired setpoint temperature. If set to Yes, the
user setpoint option is locked and the user cannot set the desired setpoint temperature. A lock symbol appears indicating
that the setpoint is locked.
5. “adjust intern setpnt”
Default:
Range:
Increment:
22.0ºC [72ºF]
10.0 to 40.0ºC [50 to 104ºF]
0.5ºC [1ºF]
Set the desired temperature setpoint within the defined range. If the setpoint option was locked in Step 4, a lock symbol is
displayed. The setpoint value is restricted by the minimum (Step 2) and maximum (Step 3) values. In other words, the setpoint
should be within in the range of minimum and maximum setpoints.
