2.1 Abbreviating keys

You often find the instruction in the text to press a key. The used abbreviation is always the
„“ brackets. The instruction to press „0„ will look like this:
Because of the danger of confusion the red key at the bottom of the controller (the 0-key)
will be called in the instructions:
is for the RAMP function, for ‘Set’ and so on.

and Appendix B incidents like Start/Stop of thermoregulation or any failure of unit can be
interpreted.
3. Physical Structure
The control electronics of the unistat control is accommodated in a separate detachable
housing. It is therefore possible to apply the valuable „Plug & Play“ philosophy which has
been part of Huber equipment for many years. It is also possible to use it in the new
generations of Unistats. Unistat control consists of two units: the electronic controller and
the control panel placed in a recess in the housing.
The control panel can be detached from the controller (a screw from above) and the
electronic connection to the controller can be made with a special cable (Order No 6147).
If the control panel is to be used via a cable connection, reference should be made to the
paragraph ‘Remote Control’.
