Wiring
We strongly recommend that all Neptronic products be wired to
a separate grounded transformer and that transformer shall
service only Neptronic products. This precaution will prevent
interference with, and/or possible damage to incompatible
equipment.

Setpoint and User Control
1. “Intern Temp Sensor Offset”
Range:
Offset:
Increment:
0ºC to 50ºC [32ºF to 122ºF]
Max. ± 5ºC [± 9ºF]
0.1ºC [0.2ºF]
Compare the displayed temperature reading with a known value from a thermometer or other temperature sensing device. To
offset or calibrate the sensor, use the arrow buttons to set the desired temperature reading. This is useful for controllers
installed in areas where the temperature read is slightly different than the room’s actual temperature. For example, a controller
placed right under the air diffuser.
2. “Minimum User Setpnt”
Default:
Range:
Increment:
15ºC [59ºF]
10ºC to 40ºC [50ºF to 104ºF]
0.5ºC [1.0ºF]
In Operation mode, you cannot decrease the setpoint to less than the value set as the minimum user point. The minimum value
is restricted by the maximum value set at Step 3 “Maximum User Setpnt”. In other words, the value that is set as the minimum
cannot be greater than the maximum value.
3. “Maximum User Setpnt”
Default:
Range:
Increment:
30ºC [86ºF]
10ºC to 40ºC [50 to 104ºF]
0.5ºC [1.0ºF]
In Operation mode, you cannot increase the setpoint to more than the value set as the maximum user point. The maximum
value is restricted by the minimum value set at Step 2 “Minimum User Setpnt”. 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)
No (Unlocked), yES (Locked)
If set to No, the user setpoint option is not locked and the user can adjust the desired temperature setpoint. If set to yES, the
user setpoint option is locked and the user cannot set the desired temperature setpoint. A lock symbol appears to indicate
that the setpoint is locked.
5. “User Setpnt”
Default:
Range:
Increment:
22ºC [72ºF]
10ºC to 40ºC [50ºF to 104ºF]
0.5ºC [1.0ºF]
Set the desired temperature setpoint within the defined range. If the setpoint option was locked at Step 4 “User Setpnt locked”,
a lock symbol is displayed. The setpoint value is restricted by the minimum at Step 2 “Minimum User Setpnt” and maximum
at Step 3 “Maximum User Setpnt” values. In other words, the setpoint should be within the minimum and maximum setpoint
range.
6. “Temp Control Mode”
Default:
Range:
Auto (Automatic)
Auto (Automatic), HEAt (Heating Only), COOL (Cooling Only), On (Cooling or Heating),
CLHt (Automatic only)

yES (Enable), No (Disable)
If set to yES, the user can set the unit to “Off” via the Control Mode (see page 27). If set to No, the “Off” selection does not
appear in the Control Mode.
