Page 30: Maintenance
Zehnder Eversky 10.2.4. Maintenance The condensate pump needs to be cleaned regularly with bleach to maintain the correct operation of the internal valves and the level detection device. The maintenance frequency should be adapted to the environment in which the ventilation unit operates. - Page 31 Zehnder Eversky Stage Description Position the pump on the bracket and insert the pump suction connection into the elbow sleeve. Install the clear PVC tube supplied in the kit on the pump's discharge connection. Pull the clear PVC pipe to the desired discharge point, taking care not to bend or pinch it.
-
Page 32: Installation Of The Anti-Siphoning Device
Zehnder Eversky 10.2.7. Installation of the lifting pump If the end of the discharge tube is below the level of the lifting pump, there is a risk of siphoning from the pump, which may lead to failure through repeated dry running. To avoid this, it is therefore necessary to install the anti-siphoning device supplied in the condensate pump kit. -

Page 36: Setting The Time Programmes
Zehnder Eversky 14.4. Setting the time programmes The operating principle of the Zehnder Eversky unit is to continuously adjust the airflow rate according to the CO₂ level measured in the room to be ventilated by acting on the speed of the fans in order to always optimise comfort and energy consumption. - Page 37 Zehnder Eversky Recommended settings: Night cooling Normal speed Low speed hh:mm 00:00 06:00 12:00 18:00 24:00 Night cooling period Druration 07:00 Period of occupancy of the building 08:30 19:00 In the diagram above, the crosses (x) indicate the time range during which the function should not be active.

Page 38: Ventilation And Co₂ Management Setpoint Adjustment
Zehnder Eversky 14.5. Ventilation setpoint adjustment and CO₂ management The principle of CO₂ regulation is to control the speed of the fans (and therefore the airflow) according to the level of CO₂ in the air in the room. The higher the CO₂ level, and therefore the higher the occupancy rate, the faster the fans turn, and therefore the higher the airflow (air change). - Page 39 Zehnder Eversky Removal of residual moisture from the room ■ Correct operation of supply and extract air fans control of their operation. ■ Minimum access level: Service Access path to the CO₂ threshold settings: Manual / Auto Ctrl CO2 / VOC Ctrl CO2 / VOC active: Settings Fire function...
