ALRE Climate controller

Electronic surface-mounted climate controller for heating and cooling regulation in 2-pipe and 4-pipe systems for hotel, residential, and commercial spaces. Designed to control continuous valve actuators, both normally closed and normally open. The switch allows selection between the operating modes Off, Comfort, and ECO. With the option for dew point monitoring, it is particularly suitable for cooling ceiling regulation. To compensate for the inertia of control loops with cooling ceilings, the device features a temperature sensor input for connecting an external radiation sensor (optional). The factory-set zero point of approximately 21°C can be adjusted within the device by +/- 5K. The setting knob allows the desired temperature to be adjusted by +/- 3K around the set zero point. As a variant for authorities, where the controller should be inaccessible to unauthorized persons, the external sensor can also be configured as a room sensor (optional). An internal potentiometer allows the selection of the use of the internal sensor, the external sensor, or both sensors with adjustable weighting. Contact inputs for ECO function and Off (frost protection).
