Description
These temperature control machines have been designed to be used with either external closed systems (e.g. jacketed reactors) or the internal bath.
For temperature control devices with compressor cooling, the low internal volume combined with high performance refrigeration and heating technology, gives a very short cooling and heating time compared with conventional bath technology.
With the integrated speed controlled pump fitted in the table models and some floor standing models, it is possible to control flow and / or pressure of the thermal fluid and thus can be exactly adapted for the required application.
With help of the self optimising cascade controller, you obtain the optimum control
results under steady state conditions as well as by set point changes and with exothermic reactions. One can choose between aperiodic or with a small overswing
(faster) control.
Information and temperature development can be easily read via the large graphic display screen (with touch screen) as well as give command inputs.
A comfortable menu guidance eases the operation of the machine. The software package Basic, Exclusive and Professional offer high functionality and comfort in usage for users with simple temperature control tasks up to demanding temperature control tasks. For a small extra charge the functionality can be extended by E-Grade. Here you have the possibility to upgrade your package from Basic to Professional via an activation key (please contact our Customer Support).
The optional Com.G@te with the digital interfaces RS232, RS485, the analogue 0/4-
20mA or 0-10V interface as well as various digital in and output possibilities (all according to the NAMUR), and fitted as standard, the machine (valid for Basic,
Exclusive and Professional) can be fitted without problem into many laboratory automation systems.
The removable CC-Pilot can be used as a remote control.
External temperature control requirements can be easily met (requirement E-Grade Exclusive or Professional) via the external Pt100 connection (NAMUR standard).
The integrated temperature-ramp function as well as the internal programmer
underline the high level of operator comfort. The integrated programmer offers the possibility of 3 different temperature programs each with 5 program steps (E-Grade Exclusive) or 10 different temperature programs with a maximum of 100 steps (E-Grade Professional), which can be made and then called up.
The thermostat uses an over-temperature protection in accordance with DIN EN 61010- 2-010, which is independent of the actual control circuits.

d
Optional at the manufacturer`s discretion.
Your temperature control unit is designated a Class III FL.
The type and function of the over-temperature protection and low-level protection is dependent on the temperature control unit.
Monitoring of the over-temperature is the same for all CC-Thermostats. As, there are models with two sensors and models with only one sensor. Two diferent types of low-level protection are available (depending on the model):
1. Temperature control machines with classical float (e.g. ministats)
2. Temperature control machines with an electronic low-level protection (e.g. K6- cc-NR)
13
To 1. Temperature control machines with classcial float
The most common and known type of level monitoring is the mechanical float. The float swims on the surface of the thermal fluid in the bath, and leads to a switching system. Depending on the level of the thermal fluid, the electronics will either signalize an OK state (with sufficient filling of the thermal fluid) or a non OK state (with insufficient filling of the thermal fluid). The float system function should be checked from time to time. In order to do this, whilst in standby mode, push the float in the bath downwards with a tool (e.g. screw driver). The electronics should then trigger an alarm.
To 2. Temperature control machines with electronical low-level protection (ELO)
ELO: Electronic over-temperature and low-level protection in combination
Some temperature control machines (depending on the model) possess an electronic over-temperature and low-level protection. Instead of a mechanical float switch temperature sensors are mounted on the surface of the heating coils to monitor the over-temperature at a potential ignition source and to ensure that the critical temperature at the heating coils (burn point of the thermal fluid) is controlled by the controller (not valid for chillers, liquid level is determined by electrical capacity) via the graphical display (60) error message will be given out.
A mechanical tool is no longer required to change the over-temperature settings. The over-temperature switch can only be adjusted after the user has re-entered a code displayed on the CC-Pilot´s display (60). This procedure avoids unintentional changes being made to the setting and replaces a mechanical tool by software.
A new feature is the Process Safety function. This function provides further protection for the operators and application. A classic over-temperature device unit would trip and cause a shutdown if over-temperature cut-off temperature was reached. This could occur under circumstances where more heat was being generated by a process (exothermic) than the unit could remove. Switching the temperature control unit off would remove the only possible method of cooling the application down. Consequently, the temperature would be able to further increase, creating a risk of injury to personnel or damage to the application, for example by over-heating a liquid into pressurised vapour. Using the Process Safety function, the controller recognises when the over-temperature cut-off is reached, and switches the cooling on. The compressor automatic is automatically set to always on. Even if the temperature continues to rise, the refrigeration machine will increase its cooling to maximum to minimise the heating. Please also note chapter on Setting the over-temperature (OT) switch.

Danger!
Emergency Procedure: Disconnect Electrical Power!
Turn the Mains isolator (36) to “0”! Dangerous liquid / vapours from temperature control unit or connected hoses (very hot, very cold, dangerous chemicals) and / or fire / explosion / implosion: Evacuate the area, following local regulations and procedures to prevent injury or loss of life! Refer to the MSDS Safety information for the thermal fluid concerned!
Environmental Conditions
This unit, and operations, will comply with DIN EN 61010-1:2001, only when it is located in suitable environmental conditions.
- for indoor use only;
- installation site ≤ 2000 m altitude;
- installed on a level, even, non flammable surface;
- maintain a clearance above and around the unit of 10 cm for water-cooled units,
and 20cm for air-cooled units, to allow air to circulate around the unit;
- for ambient temperature conditions please refer to the technical data sheet; remaining within these ambient conditions is imperative in ensuring accurate operation;
- maximum relative humidity of 80% up to 32°C, decreasing linearly to 50% relative humidity at 40°C
- use only as long a power cord as necessary;
- the unit should be located so as not to restrict access to the mains power
switch;
- mains voltage should be ±10% of the rated value;
- avoid voltage spikes;
- transient voltage surges as they occur normally in the supply grid;
- clean rating 2;
- overvoltage category II
15
Operating conditions
Please make sure that the application and system performance is dependent upon the temperature range, viscosity, and flow rate of the thermal fluid:
- Please ensure that the power supply connections are correctly dimensioned.
- The temperature control device should be located so, that sufficient fresh air
is available even when working with water cooled units.
- Please note that hose connections should be compatible with the thermal
fluid used and the working conditions.
- When choosing the thermal fluid, not only minimal and maximum
temperatures have to be complied with but also have to be suitable regarding burn point, viscosity and / or freezing. Furthermore the thermal fluid has to be compatible with all the materials used in the unit.
- Pressure changes with the length of hoses (keep as short as possible).
Choose as large a diameter of hoses as possible (the width of the pump connections are considered as a point of reference) and may negatively affect temperature control results. Flow restrictions may occur if a too narrow connector is selected for corrugated hoses.
- The use of unsuitable hoses or hose connections may cause thermal and
toxic injury to personal and environment. Temperature control hoses and their connections have to be insulated / secured against contact / mechanical damage.
- Non-suitable thermal fluids can negatively affect temperature control and be
the cause of negative temperature results and damages. Therefore only use the thermal fluids recommended by the manufacturer and only in the intended temperature and pressure range. The application should be located on approximately the same level or lower than the temperature control device, if temperature control is to be carried out near to the boiling temperature of the thermal fluid. The thermal fluid should have room temperature when filling. Fill in the thermal fluid slowly, carefully and steadily. At the same time make sure that no thermal fluid overflows (back pressure); it is thereby necessary to wear personal protective equipment, e.g. safety goggles, thermally and chemically resistant gloves, etc.
- After filling and setting all necessary parameters the thermoregulation circuit
has to be degassed. This is a requirement for proper operation of the device and thus its application.
- In the case of pressure-sensitive applications, e.g. glass reactors, observe the
maximum inlet pressure of the temperature control device for cross section reduction or shut-off (see data sheet). Take suitable precautions (e.g. pressure limitation for temperature control devices with pressure control, bypass).
- In order to avoid danger of overpressure in the system, which could damage
the temperature control device or the application, the thermal fluid must always be adapted at room temperature before turning off and a possibly available shut-off valve must be left open (pressure compensation).
- Temperature and dynamics within the reactor are determined by the outlet
temperature. A differential temperature is created (delta T) between outlet temperature and the temperature within the reactor. This difference in
16
temperature has to be adapted, depending upon type of glass application. As the differential temperature may exceed the admissible limit values and bursts may occur. Delta T value has to be adapted to the corresponding application. Therefore please see chapter Comfort menu.
- Do not kink the hoses.
- Check hoses in regular intervals for material fatigue (e.g. cracks).
With water cooled units please pay special attention to the maximum operating temperature and differential pressure requirements for the cooling water. Therefore please refer to the technical data sheet.
Danger!
If the cooling water contains high levels of minerals, e.g. chloride, bromide then suitable water treatment chemicals should be used. Use only recommended materials to maintain the unit warranty. Further information on corrosion, (appearance and avoidance) can be found on our website www.huber-online.com
under "Download /
Safety data sheets thermal fluids / Characteristics of water".
Please refer to the sections on Intended use and general safety instructions.
Location
Caution!
- Transport the unit upright
- The unit should be mounted in an upright and secure position, on a solid, stable surface
- Place on a non flammable surface
- Keep the area around the unit clean, to avoid slip and trip hazards
- Set the brakes on the castors once the unit is in position
- Place suitable absorbent material under the unit to catch any condensate and thermal fluid spills
- Any spillage of thermal fluid should be immediately cleaned up
- For large units, check the weight / load capacity for the flooring
17
Thermal fluids
We recommend the thermal fluid shown in our catalogue. The name of a thermal fluid is derived from the working temperature range and the viscosity at 25 °C.
Examples of thermal fluids in our catalogue:
M40.165.10:
Lower working limit -40 °C Upper working limit 165 °C Viscosity at 25 °C: 10 mm
2
/s
The data sheet for the thermal fluid used is of utmost importance, and must be read before use. This data sheet should be followed.
Please note the classification of your machine according to DIN 12876 The chosen thermal fluid must be compatible with stainless steel 1.4301 (V2A)
and FKM!
The maximum viscosity of the thermal fluid may not exceed 50 mm²/s at the
lowest temperature reached!
The maximum density of the thermal fluid may not exceed 1kg / dm³ For chillers we recommend as thermal fluid a mixture of water and glycol (a
mixture is recommended that permits a temperature down to -25°C).
Information on water quality can be found on our website (www.huber-

The Unistat Pilot as well as CC-Pilot (for temperature control devices with CC-Pilot) are equipped with an internal, battery-powered clock that runs even when the unit is turned off. When the unit is powered up, the actual date and time are uploaded to the unit. The capacity of the battery means allows the clock to continue to run for a number of months. If a unit has been powered-down for an extended time, it should be powered­up and left for an hour or so before running it again. If the time and date have been lost, they can be re-entered during this period.
If after turning off and on again, the time and date have been reset, then it must be assumed that there is a problem with the rechargeable battery. In this case please contact our service department.
Event Function
The clock has a programmable event function. Using this function an operation can be set to run every day (until the function is reset in the operator menu). There are two available operations:
Acoustic signal: The unit will generate an acoustic signal for about 15 seconds.
Program Start: When configuring the calendar to start a program, the user will be asked for the number of the program to be started. The program will then be started at the set time and date, even if (manual) temperature control had not been previously started.

Find control parameters
Several options of controller parameterisation are available:
1. Fast identification (valid as from E-Grade Exclusive)
2. With preliminary Test (valid as from E-Grade Exclusive)
3. Estimate control parameters (valid as from E-Grade Basic)
1. Fast identification:
Delivers a relatively fast and reliable control parameter with which a rapid regulation with a relatively high constancy can be reached. First, start temperature control and run for some minutes to achieve a suitable stable set-point. During the following do not carry out any changes on the system (e.g. filling / emptying the reactor core, change of agitator speed, change of the process sensor position etc.). After activating this function, a table with thermal fluids is displayed. Select the appropriate thermal fluid here. If your thermal fluid is not listed in the table, please select no specification. If your thermal fluid is not listed, the controller assumes a thermal fluid with characteristics, which normally results in an overshoot-free (slower) control. After selecting the thermal fluid, you are asked, whether you want to identify and control Internal or Process (cascade or set-point tracking). You are then requested to enter a set-point. Please note, that the identification is only successful, if the new set-point differs from the current set-point by at least 10 K. In the status field of the chart display (60), the information Temp. + Ident. active is displayed.
