After a couple of seconds the digital display will show the temperature and the Level LEDs will show the Level.
The temperature readout is calibrated at the factory and should be correct. If not, it may be re-calibrated as per
Appendix D.
After initialisation the System Set-up should be carried out.
Two set-up modes are possible:
a) Defaults are Enabled by means of the DIL switch. Only the alarm temperature, refrigerator no. and
time/date need to be entered.
b) Defaults are not Enabled. All alterable parameters must be entered.
Note that the following description of the system set-up procedure assumes that the default settings are not
enabled.
SYSTEMS SETUP PROCEDURE
To enter the set-up routine press the Mute and Test keys simultaneously.
The controller will bleep twice and the Version No. of the Controller firmware will be displayed.
Temperature Alarm

The Alarm Temperature is adjustable in 5 degree steps between 0 and -150 C.
If the temperature of the Thermocouple rises above this pre-set the value an alarm condition will occur.
