ALRE Climate controller

Electronic flush-mounted climate controller for heating and cooling regulation in 2-pipe and 4-pipe systems for hotels, residential, and commercial spaces. In combination with the appropriate cover set, it fits all common switch programs. Matching cover set no. JZ-007.xxx. Up to 5 valve actuators (24V~, normally closed) can be controlled per output. The switch allows selection between the operating modes Off, Comfort, and ECO. Particularly suitable for controlling cooling ceilings due to the possibility of dew point monitoring. To compensate for the inertia of control circuits 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 in the device by +/- 5K. The setting knob allows the desired temperature to be adjusted within +/- 3K around the set zero point. As an authority version, where the controller should be inaccessible to unauthorized users, the external sensor can also be configured as a room sensor (optional). An internal potentiometer allows the selection of using the internal sensor, the external sensor, or both sensors with adjustable weighting. Contact inputs for ECO function and Off (frost protection).
