Celsius / Fahrenheit
The Celsius/Fahrenheit setting sets the temperature units displayed by the Synergy Controller. The setting
is global. All temperature data are automatically displayed according to the C/F setting including currently
loaded program files.
12 / 24 Hour Time
The 12/24 Hour Time setting sets the Synergy Controller's time display to either AM/PM format or 24 hour
format. The setting is global. All absolute time data is automatically displayed based on this format.
Output 11 Control Type (Ambient Coil)
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 ramp.
Time Proportioning Mode (TPM) can be changed in a program on a step-by-step basis by selecting the OT11
checkbox when creating a program step (see
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
