2 System overview
The ZR10-D controller is an electronic control unit for controlling of up to
4 ventilation units of iV12-Smart
4 ventilation units of iV14
2 ventilation units of iV25
2 ventilation units of iV-Twin
It is characterised by easy installation and straightforward operation. The ZR10-D controller allows
control of iV12-Smart, iV14, iV25 or iV-Twin ventilation units in the following operating modes:
Heat recovery mode
Ventilation mode
Sleep timer mode (ZR10-D-Flat controller only) or
OFF mode (ZR10-D-Standard controller only)
Characteristics
Control of the ventilation system in three operating modes
LED display depending on the operating mode selected
Synchronisation of multiple controllers among each other
Integrated thermostatic switch
Variants
The ZR10-D controller is available in two models1).
ZR10-D-Standard
ZR10-D-Flat
ZR10-D-Standard and ZR10-D-Flat
recommended in spaces with the requirement that the ventilation must remain ON to maintain venti-
lation for moisture protection. The power stages of the fan can be adjusted in all operating modes.

OFF mode
The OFF mode is only selectable at the ZR10-D-Standard controller. The fan of the ventilation unit is
switched off at power stage 0.
Synchronisation of multiple controllers
The ZR10-D controller allows synchronisation of multiple controllers among each other. It rates the
line frequency via the upstream transformer automatically and generates the interval switching of the
fans. The following requirements must be met.
Each controller is connected to the power supply via its own transformer.
The transformers of all controllers operating synchronously are connected on the same power
phase (all on P1, P2 or P3) . We recommend to connect all controller power supply lines to a
common automatic circuit breaker in the cabinet.
All controllers operating synchronously must be turned on simultaneously.
A fault-free power signal is available.
