ABS plastic

Valve actuator: normally closed.

230 V AC, 50 Hz

Ambient temperature: Storage temperature: Permissible atmospheric humidity: Electrical connection: Mounting / attachment:

0 to 30 °C

It can be used as a master (pilot regu- lator) for the temperature reduction of other controllers. Controllers of series FETR, RTBSU and RTBSB are suitable as slaves (satellite controllers). Programming procedures for every day, familiar from mechanical timers, by means of ‘electronic tabs’. Shortest switching time 15 min. Load setting: The control accuracy is influenced by the different levels of intrinsic heating of the controller depending on the magnitude of the heating load. By inputting the heating load, this influence is compensated and the control accuracy is retained. General features: pilot function; ECO function, ECO value adjustable; ‘ECO’ display; ‘on / off’ display; ‘heating’ display; digital actual value display; child-safe features; pow- er reserve (approx. 4–7 days); load set - ting; actual value correction / measured value correction; learning function; valve protection; holiday setting; party setting; automatic adjustment to stan- dard / daylight savings time; mechanical range limitation; scale: degrees Celsius; reduction / comfort / automatic button; external setting; operation using direct-dial buttons; on / off button; information button; party function button; holiday setting button
