SystemAir Danvent DV, 17 3.2.8.11 Hotgas – setting of period This is the number of seconds that the hotgas valve is open. The period is relatively long, but the supply temperature is not oscillating at all and the stability of the supply temperature is sufficient. The number of seconds is a factory setting that should not be reduced. Reduction of the number of seconds will not improve the stability of the temperature to a degree that can be proven by measurements. If the number of seconds is reduced, the number of times that the valve is opened and clo

Protection and safety measures 5.1 Protection measures and additional protection measures The units are provided with guards to avoid unintended hazards and injury because of rotating parts in the unit. The potential sources of harm are the fans with fast rotating impellers. Hazards from the impellers are obvious during operation, but when power is cut-off, the impellers are still potential hazards due to after-run for at least 20 seconds. The fan guard’s are the inspection doors and the doors are provided with locks. Other motor-driven parts are dampers with da
SystemAir Danvent DV, 25 6.4.3 Valve and valve motor for heating coil The supply voltage for the water valve actuator is 24V AC, the control signal is 0-10 V. The sensor for water temperature has to be installed in the heating coil and the sensor is provided with cable but not connected to the terminals in the switchboard. The cable between valve motor and terminals in the switchboard is not delivered by Systemair. Standard valves are available for 2 or 3-way connection. Valves from Frese are only available for 2-way connection. The valves from Frese are intelligent control valves with integrated differential pressure control adjusting the v
