9.10.2. E3-DSP-CLD
As standard, the Zehnder Eversky control unit is delivered with a mobile wired local HMI housed inside the control
compartment with a 10 m cable. This HMI is directly connected to the electronic controller at the "Ext. Disp. ” port. This
cable can be extended to a maximum of 100 m.
9.10.3. Zehnder ED-Touch
Refer to the specific Zehnder ED-Touch manual for operation and connection to the electronic controller.
9.11. Firefighter remote stop (FRS)
To be wired between terminals 21 and 22 (NC dry contact) to replace the
shunt installed in the factory.
When the contact is opened, the 24 Vac power supply is cut off, which
has the effect of preventing the unit from operating (no display available).
The motorised fresh air and exhaust air isolation dampers close by means
of their automatic return spring. All actuators return to their rest position.
10. Condensate drainage
10.1. Drainage by gravity
As standard, the Zehnder Eversky ventilation unit is designed for gravity drainage of condensates (no high point). A
siphon should be installed when the ventilation unit is installed.
Failure to observe the installation rules for the condensate siphon can
lead to an overflow of the condensate tray and internal flooding of the
ventilation unit, which can cause damage to the equipment, malfunctions
and may endanger occupants and staff.
The position of the condensate drain and the type of connection interface are presented in chapter I.4 External
connections.
Provide a slope of 2 to 3% towards the condensate drain to evacuate the condensate and ensure that the drain is
neither under nor over pressurised.
10.2. Drainage by condensate pump (optional)
10.2.1. General information
A lifting pump with installation accessories is available as an optional kit if gravity drainage of the condensate is not
possible. The lifting pump enables the condensate to be drained at a higher level than the ventilation unit (e.g. on the
roof, in a side room, etc.) or if there is a high point in the drainage line. The operation of the pump does not affect the
acoustic qualities of the ventilation unit.
Failure to observe the installation rules for the condensate pump kit can
lead to an overflow of the condensate tray and internal flooding of the
ventilation unit, which can cause damage to the equipment, malfunctions
and may endanger occupants and staff.
