Celsius / Fahrenheit
The Celsius/Fahrenheit setting sets the temperature units displayed by the Synergy Nano. The setting is
global. All temperature data are automatically converted to the C/F setting including currently loaded
program files.
12 / 24 Hour Time
The 12/24 Hour Time setting sets the Synergy Nano’s time display to either am/pm format or 24 hour format.
The setting is global. All time data is automatically converted including currently loaded program files.
Output 11 Control Type
This setting is used to set the output logic for the Ambient Coil (Output 11) to On/Off control or Time
Proportioning control. In On/Off mode the Ambient Coil is either on or off depending on the controller
demand. When in Time Proportioning mode the Ambient Coil output is between 0% and 100% depending on
the demand required. The default setting is On/Off control mode. On/Off control mode typically enables the
chamber to react faster, sacrificing accuracy. Time Proportioning modes allow greater accuracy but may
slow temperature and humidity ramping.
Time Proportioning mode can be changed in a program on a step-by-step basis by selecting the OT11
checkbox when creating a program step (see Section 9.0 Programming the Synergy Nano
).
Output 11 or OT11 TPM (Time Proportioned Mode) can be monitored from within the Events screen. To
monitor the state of the OT11 TPM setting, go to the Events\Event Output folder and observe the LED light
next to the OT11 TPM label. The light is red when Output 11 is in time proportioning mode, gray when in
On/Off mode. You can monitor the Ambient Coil from the Events\Digital Outputs folder. The LED is gray
when off, red when on and yellow when in time proportioning mode.
Output 17 Control Type (Vacuum)
The Output 17 Control Type selects the type of control logic for Vacuum/Purge output. When channel 2 is
altitude, choose either the Vacuum mode or the Purge mode. Use vacuum when channel 2 units are in Torr.
