Additional zone control unit

Shadow BL – an electronic humidity restrictor (maximum humidistat).


Shadow BL – an electronic humidity restrictor (maximum humidistat). It allows one to limit the maximum humidity level in minor rooms, i.e. where the main controller is not installed. It is necessary to avoid excessive humidification. The Shadow BL unit helps to set a maximum air humidity limit. It has a touch display, which blinks off during downtime and activates by touch.

Shadow BL is a wireless controller, transmitting a control signal on a frequency of 433 MHz. The unique control signal processing algorithms allow enlargement of the operating area by several times without increasing power consumption. Its radio signal easily penetrates concrete walls, which allows one to use it in modern buildings. In case if a signal receiver (White Energy central unit) is remote, the miniature antenna that is included in the supply package should be installed.

The Shadow BL unit has an rechargeable battery, which should be charged by the supplied adapter once per half of a year or even rarely (depending on conditions of use).

To avoid significant decrease of operating signal range do not install Shadow BL on a metal surface or on a wall with massive metal elements located nearby.

Shadow BL is mounted on any surface by means of a supplied fastener.
