ECO GOLD25/08/2011/ YACE0088 Device description 113 Device description3.1 Device typesHeating thermostatsThe type designation of the LAUDA heating thermostats is composed of the prefix E for ECO, the ap-proximate 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 devicevariant.With the heating thermostats with a transparent bath there is the prefix of ET for the ECO transparentbath, 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 litersin the GOLD device variant.Cooling thermostatsThe type designation of LAUDA cooling thermostats is composed of the prefix R (to identify the coolingthermostat: 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 minimumtemperature of -15 °C.Where applicable the type designations are supplemented by a W for "water-cooled" and/or N for "Natu-ral refrigerant".3.2 PumpAll 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 controlcircuits. An additional output is used for internal bath circulation. By switching the selector at the front onthe 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 witha 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 practicableto keep the temperature difference between the bath and external consumer small even a higher tem-peratures.The pump connection of the outflow can be closed without any detrimental effects on the pump.Pump characteristics (Ì 10)3.3 ProgrammerThe devices are equipped with a programming function (Ì E).3.4 InterfacesIn the basic version the devices are equipped with a USB interface. This enables, for example, the con-nection of a PC and operation with the thermostat control software "Wintherm Plus". In addition softwareupdates are possible via the USB interface. The connecting lead is not included in the items suppliedwith the thermostat. When connecting up, make sure the correct plug is used.
