3.5. Bath setup
The key settings on the Optima can be changed by selecting Bath from the Setup option on
the main control window menu.
3.5.1. On timer completion
This section allows the timer period to be set and defines the behaviour when the countdown
timer reaches zero. This behaviour is only applicable to the GR150 and GP200 models.
3.5.2. Presets
This section allows the set temperature and pump speed to be configured for the three
presets. Pump speed configuration is only available with the TXF200 model.
3.5.3. Alarms
This section allows alarms to be set during normal operation. A high and/or low alarm can
be set up. There are three types of alarm:
 Disabled – No alarm
 Fixed – Alarm triggered at a fixed temperature
 Deviation – Alarm triggered when the deviation from the set temperature is exceeded
The alarm temperature defines either a fixed temperature or a deviation temperature
depending on the alarm type. The checkboxes define the actions taken if an alarm is
triggered. The Buzzer and Relay 1 can be switched on and latched if a persistent alarm is
required. Relay 2 is only available with a GP200. Alarm Hold Off specifies the time before
the alarm actions are retriggered once an alarm has been acknowledged. Alarms can be
acknowledged by clicking on the temperature alarms box. The TX150/TXF200 user manual
has further information on the implementation and behaviour of the alarms.
