3.1 Function description of the temperature control unit
3.1.1 General functions
This temperature control unit is designed for externally closed applications . This controller genera-
tion is characterized by the fact that there is only a single hardware . For a license fee you will re-
ceive an activation key , which allows you to quickly expand the functionality of e.g. a simple tem-
perature control unit (basic version) to its maximum functionality (professional version) at any time.
Thanks to the low internal volume and the efficient refrigeration technology , you will achieve
relatively short cooling rates .
3.1.2 Other functions
The self-optimizing cascade control delivers optimal controller results for regulating levels up and
down, both with setpoint changes and also with exothermic reactions . Temperature control can be
either a-periodic or with a slight overshoot (faster).
Your temperature control unit can be easily integrated into many laboratory automation systems.
This is provided for by the existing standard interfaces Ethernet, USB device and USB host at the
"Pilot ONE” as well as the interfaces Pt100 and RS232 at the Unichiller . The optional Com.G@te
allows you to expand your temperature control unit by digital interfaces (RS232 and RS485), an
analogue current loop interface (0/4 - 20 mA or 0 - 10 V) and various digital control options
(In/Out) .
The removable control panel (“Pilot ONE”) can also be used as a remote control . Please contact
your dealer or Huber Sales Department if you need an extension cable. The telephone number of
the Huber Sales Department can be found on page 84 in Section »Contact data« .
A connection jack for Pt100 process controller sensor enables you to accomplish external tempera-
ture control tasks with ease (requires E-grade Exclusiv or Professional).
The temperature control unit can be retrofitted with an integrated temperature ramp function and
an internal temperature programmer via an “E-grade” upgrade. The “E-grade” upgrade “Exclusiv”
enables you to set and call 3 temperature control programs with 5 program steps each by using the
integrated programmer. The “E-grade” upgrade “Professional” enables you to set and call 10 tem-
perature control programs with a total of 100 program steps by using the integrated programmer.
The temperature control unit has overtemperature protection to DIN EN 61010-2-010, independ-
ent of the control circuit itself (valid for temperature control units with heater).
Only valid for temperature control units with an emergency stop switch (optional):
By installing an >Emergency stop switch< [70], an additional protective device has been installed in
the temperature control unit. When the >Emergency stop switch< [70] is pressed (activated), all
poles of the temperature control unit are immediately disconnected.
