Brief description
The new developed CR24-.. controller generation provides the foundation for modern single room
concepts.
The technology, functionality and handling of the new microprocessor-controlled room tempera-
ture controllers are perfectly adapted to the BELIMO actuators for motorized air and water final
controlling elements.
The functional classification into three basic types with up to three output sequences and the
large number of specific applications facilitate cost-effective system solutions for individually
controlling the room climate and reducing energy consumption. The controllers can be used in
both pure VAV and combined systems with 2 and 4-pipe water applications (radiators, air heaters/
coolers, heated/chilled ceilings).
Device variants

(setpoint adjustment, mode switch and status
indication). For operation, refer to page 15.
Type CR24- A ..: same functionality as the
