Device description
The ZWU 06E controls heating charging based on outdoor temperature, adjusters, and control signals. It features a timer function for forward, backward, and spread control, and supports various external sensors. The unit is designed for series mounting in distribution boards.
Installation
Installation must be carried out by an authorized technician in accordance with local utility and VDE regulations. The unit requires 3 modular spaces in a distribution board. The external NTC sensor should be installed at least 2 meters above the floor, preferably in the main zone of use, avoiding direct sunlight and heat sources. Cables for SELV signals (external sensor, DC control signal) must be routed separately from mains power cables.
Commissioning
Initial commissioning is performed via the Menu -> Installer -> Startup path. Technicians must configure the application range (CCU or ACU), charging model (Classic or Intelligent), and system parameters. Factory settings are provided for quick setup, but adjustments should be made to match the specific heating system configuration. A commissioning certificate is included in the manual to document settings.
Operation
Users can manage the heating system through the Operation menu. Available operating modes include Standby (frost protection only), Manual (heat level 1.0 to 5.0), and Automatic (timer-based control). Users can also configure week programs and holiday programs to optimize heating performance and energy consumption.
