Function description of the temperature control unit
3.1.1
General functions
This temperature control unit is designed for
externally open 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.
Due to
powerful refrigeration engineering
,
short cooling rates
can be achieved.
Temperature control units with “P” in model name: This temperature control unit is particularly
suitable for applications requiring high pressure drops.
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.

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.
Temperature control units with a heater have an
overtemperature protection to DIN EN 61010-2-
010 that is independent
of the control circuit.

Information on the thermal fluids
Non-compliance with the safety data sheet for the thermal fluid to be used
INJURIES
Risk of injury to the eyes, skin, respiratory tract.
The safety data sheet for the thermal fluid to be used must be read prior to using it and its
content must be respected.
Observe the local regulations/work instructions.
Wear your personal protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).
Danger of slipping because floor and work area are contaminated. Clean the workplace; ob-
serve the proper disposal of thermal fluid and aids.
