10 Safety information YACE0099 / 10/9/2018
1.2 Other safety information
Only connect equipment to PE grounded mains sockets.
At higher operating temperatures, parts of the bath cover can reach surface temperatures exceeding
70 °C. Be careful when touching it Risk of burning!
Use suitable hoses (6.4).
Secure hose against slippage with the aid of hose clips. Avoid kinks in the hoses.
Check hoses from time to time for any possible material fatigue.
Thermal medium hoses and other hot parts must not come into contact with the mains cable.
With the use of thermostats as circulating thermostats hot liquid can be emitted when the hose
breaks, presenting a hazard to persons and material.
If no external load is connected, the pump outflow must be closed (use screw plugs) and the bypass
valve must be set to "internal" (4.3).
Take into account the thermal expansion of the heat transfer oils with increasing bath temperature.
Irritant vapors may develop, depending on the heat transfer liquid and operating mode used. Always
ensure that the vapors are adequately extracted. Use the bath cover.
When changing the heat transfer liquid from water to a thermal transfer medium for temperatures
above 100 °C, carefully remove all water residues, including from the hoses and loads. When doing
this, also open the screw plugs (HKN 065) (3) of the pump outputs and inputs and blow
compressed air through all the pump outputs and inputs.With higher temperature there is the
risk of burning due to delay in boiling!
Withdraw the mains plug before cleaning, maintenance or moving the thermostat.
Repairs in the control section must only be carried out by specialist personnel.
Figures of temperature constancy and display accuracy apply under normal conditions according to
DIN 12876. Electromagnetic high frequency fields may in special cases lead to unfavourable values.
Safety is not impaired.
The following action may start the thermostat unintentionally from the standby mode: Previously acti-
vated timer mode (7.12), "Start" command via interfaces (8).

4 Device description
4.1 Environmental conditions
The operation of the thermostats is only allowed under the following conditions as specified in
DIN EN 61010-2-010:2003 and DIN EN 61010-1:2001:
Indoor use only.
Elevation up to 2000 m above sea level.
Foundation must be dense, even, non-slippery and non-flammable.
Ambient temperatures range (11).
Use only within this range for an undisturbed operation.
Mains supply voltage fluctuations (11).
Relative humidity (11).
Transient over voltage according to Installation Categories (Over voltage Categories) II.
Pollution degree: 2.
4.2 Device types
The type designation of the Proline heating thermostats always begins with P for Proline. The follow-
ing numbers are equal to the bath volume in liters.
Examples: P 5 C is a Bath thermostat with 5-liter bath and Command remote control.
4.3 Varioflex pump
All units are fitted with a Varioflex pump with an 8-stage variable drive. The pump power can therefore
be optimally matched to the relevant task: High pump pressure when, for example, long hoses pass to
external loads or circulation is to be provided for a large bath. Low pressure when the heat input into
the bath must be low.
With heating thermostats P 5 C, P 8 C, P 18 C and P 26 C the Varioflex pump enables as a pres-
sure/suction pump, the very effective supply of pressure-sensitive glass reactors which have a mini-
mum permissible pressure rating.
Furthermore, open vessels can be operated when a constant level controller (accessory LCZ 0660) is
used (except P 12 C).

Proline Edition X heating thermostats
18 Device description YACE0099 / 10/9/2018
At the right-hand side and at the back of the unit outflow and inflow nozzles are fitted for external
loads. This means that up to two external loads can be directly connected without a distributor. Con-
nections which are not required must be closed off with the supplied caps and union nuts.
A bypass valve can subdivide the total volume flow variably between the bath (internally) and the
connected load (externally). Consequently, no "pump short circuit" is needed. If no load is connected
to the pump connector, the bypass valve must be set to the “internal”position for the best bath circula-
tion.
In the heating range the Varioflex pump operates up to viscosity values of 150 mm²/s. In the closed-
loop control mode 50 mm²/s should not be exceeded. The temperature control is the best with
30 mm²/s and lower viscosity.
With small bath thermostats (e.g. P 8) power level 3 to 6 is practicable.
For operation as a circulating thermostat with an external load, a higher power level is practicable to
maintain the temperature difference low, among other things also with higher temperatures in con-
junction with oils as heat transfer liquids.
The pump connections on the unit are fitted with M16 x 1 threads.
Pump characteristics (Section 11).
The pump outflows of the Varioflex pump can be closed off without any impairment to the pump. Here,
the "internal" setting of the bypass controller is recommended.
4.4 Materials
All parts being exposed to with the heat transfer liquid are made of high quality material appropriate to
the operating temperature. Non-rusting stainless steel and high quality temperature-resistant, primarily
solvent-resistant plastics are used.
4.5 Temperature display, control and safety circuit
In the Master Version, the units are equipped with a 5-character green LED display, which is used for the
display of the measurements and settings, as well as the operating status. The entry of setpoints and
other settings occurs under menu guidance via four keys.
The extra features of the Command Version include a removable console with a backlit graphical dis-
play. The entry of the setpoint and other settings occurs under menu guidance via situation-dependent
cursor keys and soft keys.
A Pt100 temperature probe acquires the outflow temperature in the bath. A high-resolution A/D converter
processes the measurement. Further measurement conditioning occurs using a special control algorithm
for controlling the heater actuator, which has a low reactive effect on the mains.
An external Pt100 can be connected via a socket (10S) for the acquisition of an external temperature.
This value can be displayed and, if required, used as the controlled variable with external control (Mas-
ter) switched on. In this way the system controls the external measurement and not the outflow tempera-
ture (7.7.4).
The safety system conforms to DIN EN 61010-2-010. The SelfCheck Assistant monitors about 50 unit
parameters, A dual-channel system is used in which two microcontrollers monitor one another. Along
with the bath temperature measurement and control probes, there are also two safety temperature
probes (Pt100) for the safety circuit for the overtemperature cut-off and for monitoring the bath tempera-
ture probe.
The overtemperature cut-off point is displayed on pressing the key on the Master.
Changing the overtemperature cut-off point: (7.2) (Switching on) on page 28.

Proline Edition X heating thermostats
YACE0099 / 10/9/2018 Device description 19
The bath level is acquired by the SelfCheck Assistant in 8 stages. A permanent display is provided only
with the Command remote control. If the minimum level is undercut, the pump and heater are switched
off. The reaction of the thermostat in case of overfill can be set to simply display a warning, to display a
warning and switch off the heater or to switch off the unit completely with pump and heater.
When the level is too low, with overtemperature, or with other alarms the SelfCheck Assistant switches
the heater off on all poles. The pump is also switched off.
This switch-off under fault conditions is retained, i.e. after the fault is rectified, the fault must be reset (re-
leased) on the Master operating panel with the key.
Other unit functions are described in the appropriate sections and in Section 7. (Starting up).

The units are equipped with a programmer function, which enables five temperature/ time programs to
be saved. Each program consists of a number of temperature/ time segments. These also include de-
tails of how often the program is to be executed. Up to 150 segments can be distributed amongst the
five programs.
With the ramp function, a rate of change can be directly entered in °C per unit time. (7.10).

4.9 Heater rating and power consumption from the mains
The Proline Low-Temperature Thermostats have an extraordinarily high heater rating of 3.5 kW maxi-
mum. If your mains fuse is rated below 16 A, the current consumption can be reduced in steps from
16 A to 10 A (0). The maximum heater rating of 3.5 kW is then, of course, also reduced accordingly.
