Special safety information
The use of the thermostat is only admissible under the following conditions:
• The siting surface must be impervious, flat, non-slip and non-combustible. Do not position the thermostat at the edge of the bench or table.
• Keep to the specified wall spacing (Ì 6.1).
• Protect the thermostat from dripping or condensing water.
• Do not store any liquids or combustible objects above the device.
• Do not work with flammable liquids in the direct vicinity of the device.
• Only connect the device to an earthed mains socket which is freely accessible.
• At higher operating temperatures parts of the bath cover can take on temperatures of over 70 °C.
There is a danger of burns.
• Only use suitable hoses. (Ì 6.4)
• Ensure that the hoses are not kinked during operation.
• Check the hoses at certain inspection intervals (Ì 8.3.2) for material fatigue.
• Hoses with hot heat transfer liquid and other hot parts must not come into contact with the mains
cable.
• When using the thermostat as a circulation thermostat, hot liquid can escape due to hose fracture
and become a danger to personnel and materials.
• Toxic vapors may be generated depending on the heat transfer liquid used and the operating mode.
- Ensure sufficient extraction of the vapors.
- Use the bath cover.
• Carefully mount the immersion thermostat on the bath vessel.
• Only use bath vessels which are suitable for the intended operating temperatures.
• When filling, set the overtemperature switch-off point according to the heat transfer liquid used.
• When changing the heat transfer liquid from water to other liquids for temperatures above 100 °C,
carefully remove all residues of water including from the hoses and consumers, otherwise there is a
risk of scalding due to delay in boiling.
To do this also remove the blank plugs on the pump inputs and outputs and blow them out with compressed air.
• Use the cooling coil with cooling water only at operating temperatures below 100 °C. At higher temperatures there is danger of hot vapors forming.
• Have repairs carried out only by specialists.
• Keep to all the service and maintenance intervals according to VDI 3033. (Ì 8.3.2)
• Take note of all safety labels.
Applicable to water-cooled devices:
• Secure the return hose of the water cooling in the discharge area in order to prevent the hose sliding
off uncontrollably, also during pressure surges.
• Secure the return hose of the water cooling in the discharge area so that it is not possible of hot cooling water to splash out.
• Avoid kinking or crushing the return hose of the water cooling. Excessive pressure can cause the
cooling water hoses to tear and hot water to escape.
• To avoid damage due to a leak in the cooling water system we recommend the use of a water leakage sensor with water cut-off.

Device description
3.1
Device types
Heating thermostats
The type designation of the LAUDA heating thermostats is composed of the prefix E for ECO, the approximate bath volume in liters and a G for the GOLD device variant.
Example: E 10 G is a heating thermostat with a maximum bath volume of 10 liters in the GOLD device
variant.
With the heating thermostats with a transparent bath there is the prefix of ET for the ECO transparent
bath, followed by the bath volume in liters and a G for the device variant GOLD.
Example: E 6 G is a heating thermostat with a transparent bath with a maximum bath volume of 6 liters
in the GOLD device variant.
Cooling thermostats
The type designation of LAUDA cooling thermostats is composed of the prefix R (to identify the cooling
thermostat: Refrigerated), an E for ECO, the bath volume in liters, the minimum attainable temperature
(without arithmetical sign) and a G for the device variant GOLD.
Example: RE 415 G is a heating thermostat with a maximum bath volume of 4 liters and a minimum
temperature of -15 °C.
Where applicable the type designations are supplemented by a W for "water-cooled" and/or N for "Natural refrigerant".
3.2
Pump
All devices are equipped with a pressure pump. The pump has an output with a pivotable outflow elbow.
With the heating thermostats this is joined to the pump connection set for external temperature control
circuits. An additional output is used for internal bath circulation. By switching the selector at the front on
the control head, the flow can be manually selected or divided between the two outputs.
Using the operating menu, one of six flow-rate levels can be selected for the pump. For thermostats with
a small bath a power level of 1 to 3 is practicable.
When operated as a circulation thermostat with an external consumer, a higher power level is practicable
to keep the temperature difference between the bath and external consumer small even a higher temperatures.
The pump connection of the outflow can be closed without any detrimental effects on the pump.

For the connection of the Command remote control unit from the Proline
equipment line and other accessories, such as a solenoid valve for cooling
water control or a reverse-flow protection device.
Chiller
The chiller mainly consists of a fully hermetically sealed compressor. The dissipation of the condensation
and motor heat takes place via a fan-ventilated lamellar condenser. Here, atmospheric air is drawn in at
the front of the device, heated up and discharged at the back and sides. To ensure proper air circulation
the ventilation openings must not be covered up.
The compressor is equipped with a thermal release which responds to the compressor temperature and
current consumption. The chiller is normally switched in automatically, but can also be switched in manually via the operating menu (Ì A.3).
The chiller is switched off when a malfunction occurs which affects safety.
The Cooling Thermostat RE 1050 G is equipped with the SmartCool technology which makes optimum
use of the compressor and only chills when cooling output is demanded by the controller. To achieve
this, several sensors in the cooling circuit monitor the operating status.
Cooling times for the various cooling thermostats can be taken from the cooling curves (Ì 10).

Note:
−
Always use the largest possible cross-section and the shortest possible hose lengths in the external
circuit.
−
For a hose cross-section that is too small a temperature gradient occurs between the bath and external consumer due to a volume flow that is too low. In this case increase the bath temperature or the
pump level appropriately.
−
Secure the hoses with the aid of hose clips.
−
If the thermostat is to be externally controlled, a temperature sensor must be fitted in the external
consumer.
−
If the consumers are situated at a higher level and with the pump stopped and air seeping into the
external fluid circuit, then even with enclosed circuits the external volume may run empty. There is
danger of the thermostat overflowing.

Heat transfer liquids, cooling water and hoses
Note:
−
Tap water is unsuitable for operation with the thermostat due to the calcium carbonate content. The bath
vessel may calcify.
−
High purity water (from ion exchangers) and distilled or bidistilled water are unsuitable for operation due
to the corrosive properties of these media. High purity water and distillates are suitable as a medium after
the addition of 0.1 g of soda (Na2CO3, sodium carbonate) per liter of water.
−
Water containing iron (rust formation), chlorine (pitting) and untreated river water ("algae formation") is
unsuitable.
−
The bath vessels of the LAUDA ECO thermostats are produced in stainless steel 1.4301 and are accordingly resistant to mechanical and chemical stresses.
−
Metals have different electrochemical potentials. Therefore, in the case of direct contact between the tank
and a frame (copper for example) electrochemical oxidation may occur. The bath corrodes despite the
use of high quality materials on the tank. Avoid the use of this type of frame or direct contact with it or
contact with non-ferrous metal samples and the inside of the container. Use original LAUDA stainless
steel frames or commercially available frames in temperature-resistant plastics.

The cooling circuit is largely maintenance-free. Remove
dust and contamination from the condenser at regular intervals (depending on operating period and exposure conditions).
−
To do this, remove the front grille by grasping it at the
bottom with both hands and pulling the grille to the
front. To avoid damage, remove the front grille slowly
and carefully.
−
Then brush down the condenser and, where necessary, blow it out with compressed air.
Note:
Contact with sharp-edged vanes on the condenser
during cleaning

Decalcifying the cooling water circuit
At regular intervals of 3 months or longer (depending on the water hardness / degree of contamination
of the cooling water) the water-cooled condenser must be decalcified or cleaned.
Required equipment:
−
Two containers of 10 to 20 liters.
−
Use a suitable pump (drum pump) or possibly use hose with a funnel with funnel located
above the cooling water inlet.
Hose between container, pump and cooling water inlet and also between cooling water outlet and container.
Standard
Alternative
Cooling water connections
Interchange containers when top one is
empty
Via the water inlet hose, fill the device with decalcifier (pump or hose). Set the set value to 10 °C; after
the chiller starts the water circuit can be filled. Circulate the decalcifier with the pump or continue to top
up the decalcifier. Allow the decalcifier to have an effect (see table below). Then drain the device.
Again connect the device to the water supply and thoroughly flush it out (see table below).

Acting time
Continue with the pumping process until the foaming reaction decays. Generally, this is
achieved after about 20 to 30 minutes.

External control
The devices can also be optionally controlled via an external Pt100 temperature sensor, which can be
connected at the back of the control head. It is necessary to install an external Pt100/LiBus module (Ì

Furthermore, the signal coming from an analogue or serial module can also be controlled. Analogue
module and contact modules are available as accessories (Ì 9).

Setpoint offset operating mode (Diff.set/actual)
It is possible to apply an offset value to the temperature, which is provided by an external temperature
sensor and to process it as the set value.
The bath temperature can therefore be operated, for example, -15 °C below the temperature of a reactor measured by the external temperature sensor.

Programmer
The programming function enables you to save five temperature/time programs. The programs consist of
a number of temperature/time segments and details about their repetition. The total number of freely
programmable segments is 150. Temperature step changes (time is zero) or also temperature retention
phases for the same start and end temperatures in the segment are possible.
On starting the current set value is taken as the starting value of the first segment.
Changes to the pump level are entered in the relevant line. If the pump level is to remain unchanged, "0"
is entered (display shows "---").

The tolerance entry can have a large effect with
external bath control. The adjacent graph of the
edited trace shows the possible run-on of the actual temperature in the bath vessel (continuous
line) for the set-point temperature of the programmer (highlighted in gray).
Note:
− The tolerance field facilitates exact conformance to the dwell time at a specified temperature. The following segment is only processed when the actual temperature reaches
the tolerance band n, so that for example the
ramp of segment 2 is only started delayed by
o.
− A tolerance range which is too tight can however also cause undesired delays. In particular with
external control the range should not be chosen too tightly. In Segment 5 a larger tolerance has
been entered, so that the desired time of ten minutes is maintained even with settling action p.
− Only flat (slow) ramps should be programmed where necessary with a tolerance range. Steep
ramps which lie close to the maximum possible heating or cooling rates of the thermostat may be
severely delayed by a tolerance range that is too tight (here in Segment 2) q.

Note: No time specification is possible in the start segment (No. 1). The temperature of the first segment
is attained as quickly as possible in order to switch to segment 2 after reaching the set tolerance.

Delete a segment.
Note:
− New segments and be inserted and existing ones changed, also the currently active segment, even
when a program is currently being executed. Furthermore, except for the currently active segment,
all segments can be deleted at any time.
− Changes to the currently running segment are possible. The segment is continued as though the
change has been valid since the start of the segment.
− If the new segment time is shorter than the already expired segment time,
then the program skips to the next segment.
− If a segment time is required > 999h: 59min, then this time must be spread over several consecutive segments.

Control parameters
The control parameters have been optimized at the factory for operation as a bath thermostat (with water
as the heat transfer liquid) with internal control. The standard parameters are already set as default also
for the thermostatic control of external applications with external control.
Depending on the application, the configuration can be adapted from case to case as required. Also the
thermal capacity and the viscosity of the heat transfer liquid affect the control behavior.
Note: Only change the control parameters if you have adequate knowledge of control techniques.
F.1
Internal control variable (internal temperature sensor)
If you have not connected any temperature sensor, read further here. For activated external control read
(Ì F.2).
The control corresponds to the set-point temperature with the current bath temperature and calculates
the set value for heating or cooling.

F.2
External control variable
The setting options illustrated in this section are only possible with a connected external temperature sensor or with an existing module (as activated as control variable in Section D.1) for reading in the actual
temperature.
The control system for external actual values is realized as a two-stage cascade controller to improve the
response to setpoint changes. From the temperature setpoint and the external temperature, which is generally measured by the external Pt100, a "master controller" determines the "internal setpoint" which is
passed to the slave controller. Its set value controls the heating and cooling.
Correcting quantity limit
If a step change in set-point temperature is specified, the optimum control might set an outflow temperature which is substantially higher than the temperature desired on the external vessel. With the correction
limitation the maximum permissible deviation between the temperature in the external consumer and the
temperature of the outflow liquid can be limited. The limit can be set via a menu point (Ì F.2.1).
These parameters can be set on the master controller (PIDT or external controller):

F.2.2 Procedure for setting the control parameters for external control
1.
Activating external control (Ì D.1).
2.
Set the slave controller:
2.1. Parameter to auto ;
Xpf in dependence of:
− Check or adjust device type (Ì 8.2.4).
− Select heat transfer liquid with as low-viscosity and with as high a thermal capacity as possible.
Ranking list: Water, water/glycol, oils, Fluorinert®.
− Set pump level as high as possible,
− Make sure there is adequate circulation,
− select the hose length as short as possible, e.g. 2 x 1 m,
− select the hose cross-sectional area as large as possible, e.g. ½ inch,
− set the throughput through the external consumer as large as possible.
2.2. Set Xpf:
− With a tendency to oscillate with a short period of oscillation (e.g. 30 s) Î Xpf smaller, otherwise
larger,
− with poor thermal coupling and a large mass to temper Î large (e.g. 2...5, possibly even larger),
− with good thermal coupling and a small mass to temper Î small (e.g. 0.2...0.7),
− if fast temperature changes are required, external baths should be controlled if possible with internal control. Otherwise choose Xpf to be very small (0.05 ... 0.1).
3.
Setting the master controller (PID controller):
− First start with Auto, then possibly continue with manual.
3.1. Setting Kpe:
− With a tendency to oscillate (long period of oscillation, e.g. 10 min) Î Kpe larger, otherwise
smaller,
3.2. Setting Tne/ Tve/ Tde:
− Generally quite high values (Tne = 70 s ... 200 s; Tve = 50 s ... 150 s),
− with smaller values Î faster transient responses, otherwise slower transient responses and
therefore less oscillation,
− Tve: To reduce transients Î increase Tve, otherwise vice versa,
4.
− Tde (damping for Tve): generally approx. 10 % of Tve.
Correcting quantity limit (Ì F.2.1) and temperature limits (Til/Tih) (Ì 7.4.5).
− Set according to the physical boundary conditions.

Analog module
Analogue Module (LAUDA catalogue no. LRZ 912) has two inputs
and two outputs, which are brought out to a six-pole DIN socket to
Namur Recommendation (NE28).
The inputs and outputs can be set independently of one another as
a 0...20 mA and 4...10 V interface, Various functions can be selected for the inputs and outputs. Accordingly, the signal on the
input is interpreted differently and different information appears on
the output.
In addition the interfaces can be freely scaled according to the set
function. 20 V DC is available for measurement transducers.
The following values can be defined via the inputs:
−
Set-point temperature
