All further installed JRG Legio- Therm 2T circulation controllers are still in normal opera- tion. After reaching the desired temperature (parameter 8) and after the set time (parameter 4) of 3 minutes (factory setting) or any other pre-set time has elapsed, the thermo- electric actuator closes the circulation controller. The cir- culation controller switches back to normal operation mode and cannot carry out any further thermal disinfection during a preset blocking period (parameter 5). 9

Basic installation option T sensor WW CW 24 V 230 V Powerbox 12

DIN Text JRG Nr. SIA Basic installation option The JRG LegioTherm Powerbox converts 230 V AC into 24 V DC. Thanks to the low voltage of 24 V DC, the installer can connect the installation to the power supply without any additional help. All JRG LegioTherm 2T circulation control- lers are connected in series and operate on 24 V DC low- voltage. The maximum length of the power cord is to be taken into consideration. In this case, the programming and monitoring is done at each individual JRG LegioTherm 2T circulation controller. Features of Basic installation option • Allows two calibration temperatures (normal/thermal disinfection) • Programming and control is done on them individual JRG LegioTherm 2T circulation controllers • The recent thermal disinfection temperature as well as error messages can be retrieved on the JRG LegioTherm 2T circulation controller • Only power cords 2 x 2.5 mm2 to be laid 13

Standard installation option T sensor WW CW 24 V RS 485 230 V Powerbox Master 1 DIN Text JRG Nr. SIA Standard installation option The JRG LegioTherm Master 1 allows the operator to centrally program and monitor each JRG LegioTherm 2T circulation controller. Power is supplied as in the Basic version. After the JRG LegioTherm Powerbox, a JRG Legio- Therm Master 1 is installed. The JRG LegioTherm Master 1 is connected in series with the individual JRG LegioTherm 2T circulation controllers via an RS 485 communication cable, article no. 3632. This enables a permanent exchange of data between the JRG LegioTherm Master 1 and the JRG LegioTherm 2T circulation controllers. Features of Standard installation option • Allows two calibration temperatures (normal/thermal disinfection) • Programming and control are centrally done on one JRG LegioTherm Master 1 • The process data of the thermal disinfection are logged for each circulation controller • Power cord 2 x 2.5 mm2 and communication cable 2 x 0.5 mm2 to be laid 14
