Electronic climate controller, KTRRB Surface-mounted installation – Design Berlin 3000
Technical data
Application
Design:
Berlin 3000
Single-room temperature controller with neutral zone for 2-pipe or 4-pipe air conditioners. External flow sensor (H/C sensor): For automatically switching the controller to heating or cooling mode in 2-pipe operation depending on the inflow temperature; alterna- tively, this input can be used as an H/C changeover contact. Sensor rupture and short-circuit protection: In case of a sensor rupture or sensor short-circuit, the heating is activat- ed with a power-on time of 30% to prevent cooling or frost damage in the room.

Accessories: Adaptor plate for mounting on flush-mounted socket JZ-17, terminal strips VOOxx (see page 107/141), compatible valve actuators ZBOOA (see page 144), compatible external sensors (“Sensor 2”; see “Sensor Technology”). You can find other/similar controllers with outputs for heating/cooling in the “Heating technology” section (RTBSB/RTBSU).
*With ECO operation, the neutral zone (2 K) is extended by the ECO zone (+/- 3 K). ECO operation is a savings mode that should be controlled, for example, via a window contact and/or a timer.
