2.0 Area of application
The electronic timer module ZLS-ZU 31 is designed to set automatic switching times for day/night operation. It enables
the parallel operation of maximum 31 DVEC roof fans. The timer module is operated via the main rocker switch. The
day/night switchover is carried out via the settings on the display (see attached operating instructions for timer).
The units are designed for use in ambient conditions with common contaminants.
Application and operation only in compliance with these installation and operating instructions.
Any use other than the intended use is prohibited!
2.1 Safety
- Maintenance and installation work may only be carried out by an authorised electrician.
- The unit may only be operated with the nominal voltage specified on the type plate.
- The technical data on the type plate must always be observed.
- The protection category specified on the type plate shall only apply if the unit is installed according to its intended use
pursuant to these installation and operating instructions.
2.2 Electrical connection
The unit must be fully isolated from the mains power supply before all maintenance and installation work or
opening the terminal compartment! The electrical connection may only be carried out by an authorised
electrician according to the following wiring diagrams (page 7).
The relevant safety regulations and standards must
be observed (e.g. VDE 0100, VDE 0530 and VDE 0700 and the technical connection regulations of the energy supply
company). The mains voltage and frequency must correspond to the details on the unit rating plate.
3.0 Commissioning
The following checks must be carried out:
– Check designated use of unit
– Compare mains voltage to rating plate data
– Compare power consumption to rating plate data
– Check timer for solid mounting
– Check the waterproofing of the connection cable and tight clamping of the strands
– The timer is in power saving mode upon connection. The time and date are set to factory settings.
The “colon” display will flash. Press any key to activate the timer.
– If multiple DVEC fans are connected to the ZLS-ZU 31, the “address” parameter in the menu must be changed to a
ZLS-BDT or ZLS-IF incl. laptop. In this respect, read the “ZLS-DVEC quick guide” (section 04, page 6).
The keys must not be operated with metallic, sharp objects (e.g. needle)!
