Options for ventilation operation

The ComfoSpot 50 can also be equipped with optional accessories for convenient operation and demand-controlled
ventilation mode.
NOTE
Ventilation operation by means of optional accessories requires the installation and configuration of those accessory
components.

External control panel

The Zehnder ComfoLED external control panel offers the possibility to operate the ventilation unit at a distance from the
integrated control unit. The operating and display elements of the external control panel correspond to those on the internal
control panel installed on the unit. If an external control panel is installed, the internal control panel supplied as standard
remains fully functional.

Operation via networking

3.2.2.1 Operation via radio module
Ventilation units in a ventilation zone can be easily networked with each other using radio modules. The function of the
ventilation units is synchronised. The settings are still made on the internal or external control panels.
Mixing systems with ComfoAir 70 series ventilation units in a common ventilation zone are possible.
3.2.2.2 Operation via the connection hub and Zehnder Connect App
Using the connection hub and Zehnder Connect App, ventilation units with a radio module in a residential unit can be
conveniently operated via a mobile device. This allows complex networks to be set up. The central point of these networks
is the Zehnder connection hub. It serves as an interface between the ventilation units, the mobile end devices (app) and,
if available, a WLAN network with Internet connection for operating the units while away.
Mixed systems with ComfoAir 70 series ventilation units in a common residential unit are possible.
Description
Frost protection From an outside air temperature of -4°C, the frost protection function is
mode automatically activated.
In frost protection operating mode, the ratio between the supply air and
extract air volume flow is automatically adjusted depending on the
outside air temperature, and the unit is shut down if the outside air
temperature is lower than -15°C. A check is made regularly as to whether
the temperature conditions in regard of frost protection have changed,
and the respective operating mode (requiring frost protection) is
activated automatically according to the result of that check.
After the unit is switched off, a flashing in those LEDs (by touching the
(+) or (-) key) which denoted the most recently active fan speed will be
signalled. The fan speed cannot be changed and is signalled with the
flashing of Fault LED
NOTE
Changing from a higher to a lower fan speed may not be possible
depending on the currently active frost protection routine.
Indication of If an inaccessible operating mode is selected, it will be signalled by the
locked modes flashing of Fault LED.
These operating modes are the locked standby, locked supply and
extract air mode and complete switch-off due to frost protection.
Indication Filter The filters are monitored based on running time. 90 days are preset by
maintenance default.
After the filter runtime has elapsed, notification in regard of a filter
maintenance is signalled by the filter maintenance LED flashing.
Simultaneously touching the (+) and (-) keys for 3 seconds allows you to
acknowledge the indication of the filter maintenance and to reset the filter
runtime.
Signalling of error If an error occurs, this is signalled by the fault LED.
code fault
Faults that can be diagnosed by the unit are symbolized by LED1-4 using
message
an error code.
Simultaneously touching the (+) and (-) keys for 3 seconds allows you to
delete the indication of the fault notification.
