Electronic flush-mounted climate controller for heating/cooling control in 2- and 4-pipe systems for hotels, residential and business premises. In conjunction with the corresponding cover set, it fits into all common switch ranges. Matching cover set no. JZ-007.xxx. Up to 5 valve drives (24V~, closed when de-energized) per output can be controlled. The switch can be used to choose between the operating modes Off/Comfort/ECO. Particularly suitable for cooling ceiling control due to the option of dew point monitoring. In order to compensate for the inertia of control systems with cooling ceilings, the device has a temperature sensor input for connecting an external radiation sensor (optional). The factory-set zero point of approx. 21°C can be adjusted in the device by +/- 5K. The target temperature can be adjusted in the range of +/- 3K around the set zero point using the adjustment knob. As a variant for authorities, where the controller should be inaccessible to unauthorized persons, the external sensor can also be designed as a room sensor (optional). An internal potentiometer can be used to select the use of the internal, the external or both sensors with an adjustable weighting. Contact inputs for ECO function and OFF (frost protection).
