3 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
Example: RE 420 G is a heating thermostat with a maximum bath volume of 4 liters and a minimum temperature of
-20 °C. Where applicable the type designations are supplemented by a W for "water-cooled".
Viscothermostats
The name of LAUDA viscothermostats is composed of "Viscotemp" at the start followed by the approximate bath vol-
ume in liters and a G for the model, GOLD.
3.2 Pump
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.

3.4 Interfaces
In the basic version the devices are equipped with a USB interface. This enables, for example, the connection of a PC
and operation with the thermostat control software "Wintherm Plus". In addition software updates are possible via the
USB interface. The connecting lead is not included in the items supplied with the thermostat. When connecting up,
make sure the correct plug is used.
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.
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.
All devices are equipped with a pressure pump. The pump has an output with a pivotable outflow elbow.
