Description
Locking the set point (cont’d):
Select the desired locked set point temperature. Note: This value must
respect the temperature range of the selected temperature sensor – either
internal or external at step #11A (see Technical Data table on page 1).
Once locked set point temperature is selected, please go directly to step #5
Minimum set point:
Set point range : 0 to 60ºC [32 to 140ºF]
Increment: 1ºC [1ºF]
Default value: 22ºC [72ºF]
2B
Display switches between “Stp” and the minimum set point temperature. MIN
symbol is also displayed. Select the desired minimum set point temperature.
Note 1: The minimum value cannot be set higher than the maximum value
set in step #4. Note 2: When adjusting this value, please consider the
selected temperature sensor’s range – either internal or external at step
#11A (for range, see Technical Data table on page 1).
Maximum set point
Display switches between “Stp” and the maximum set point temperature.
MAX symbol is also displayed. Select the desired maximum set point
temperature. Note 1: The maximum value cannot be set higher than the
minimum value set in step #3. Note 2: When adjusting this value, please
consider the selected temperature sensor’s range. Set to either internal or
external at step #11A (for range, see Technical Data table on page 1).

Default value: Out
(External temperature
sensor)
If you select internal temperature sensor, go directly to step #12.
External temperature sensor Calibration:
Display switches between “tS2” and the temperature read by the external
temperature sensor (if connected).
You can adjust the calibration of the external sensor by comparison with a
known thermometer.
Night set back derogation time :
Range: -40 to 100ºC [-40 to 212ºF]
Increment:1ºC [1ºF]
-40ºC [-40ºF]: resistance = infinite.
100ºC [212ºF]: resistance = short
circuited (alarm [!] is displayed).
Display switches between “nSb” and the derogation time in minute. MIN and
NSB symbol is also displayed.
Please select the desired derogation time, if no derogation time is desired
select “OFF”.
