Electronic climate controller with timer KTRRUu – 230 VAC Flush-mounted installation – Design Berlin UP
Technical data
Application
Design:
Berlin UP (flush-mounted) PC, PMMA, ABS plastic
Flush-mounted controller with timer function for heating/cooling regulation of 2- and 4-pipe systems used in hotels, homes and offices. The adaptation takes place in a menu. The unit can control up to 5 valve actuators (normally open or normally closed) per output. In 2-pipe operation, the operating mode can be changed via an external contact (changeover) or a temperature sensor. The clock can serve as a master for other controllers for switching to ECO mode. It is possible to activate the energy saving (ECO) or frost protection (OFF) functions via an external contact. Alternatively, the controller”s inputs can be configured to connect with an external temperature sensor or dew point sensor (TPS).

* A menu setting can be used to select whether control should be based on the internal or external sensor. In the intermediate positions, if both sensors are used, a weighting is applied to the internal room sensor and the external radiation sensor. The weighting allows for compensation of different struc- tural conditions such as large window areas or cardinal directions. For very slow controlled systems, it is recommended to assign a higher weighting to the radiation sensor than to the internal room sensor.
