The table also indicatesthe total electricity consumption of the fans in each case.150402926031309041651255215160624520072752358330305Remember:Never turn DIGIT off,or else you'llkeep catching a cough.4INSTRUCTIONS FOR USE2.Instructions for use: VALLOX DIGIT SEIn order for indoor air to remain healthy, also for the structures of thebuilding,ventilation has to be in continuous operation. Do not stop ventilation even forlonger holidays, because that will make room air musty, and during the heatingperiod room air humidity may condensate in theducts and the structures, therebycausing humidity damage. The sensors automatically set ventilation to an optimallevel even if the house is empty.2.1. Taking into use1. Connect the plug into the power supply. VALLOX DIGIT SE is now readyforoperation.2. Start the unit and select an appropriate ventilation rate on the controlpanel.The unit includes one or more control panels. For instructions on how to usethem, see Section 3.2.1. and 3.2.2.In normal conditions, basic ventilation is adequate, which means that air isreplacedonce every two hours. Increased ventilation is neededduring sauna baths, cooking,washing of clothes or family parties. If CO2 and humidity sensors have beeninstalled in the system, VALLOX DIGIT SE will also take care of demand controlledventilation.2.2. Ventilation controlThe unit can be fully controlled with the control panel delivered with the unit or with an optionalLON converter.The standard week clock control can be used to control the fan power of the unit and thesetpoint for supply air temperature.Furthermore, demand controlled ventilation can be adjusted with optional carbon dioxideand humidity sensors.The fan power of the unit can also be controlled with a voltage or current signal.2.3. Ventilation control with control panelThe following ventilation control functions can be performed at the control panel:Ventilation rate regulation• Starting and stopping• Capacity regulation (8 positions).• Setting the basic fan speed and the maximum fan speed. Ventilation rate cannot be setlower than the basic fan speed. When CO2 and/or %RH adjustments are activated,capacity cannot be adjusted to exceed the maximum fan speed. When CO2 and %RHadjustments are not enabled, fan speed can be raised to speed 8.Supply air temperature control functions• Switching the electric or water-circulated post-heating unit on or off.• Setting the desired supply air temperature (+10°C...+30°C).• Choosing the control mode for desired supply air temperature (constant temperaturecontrol, cascade control).Preheating• Setting the control temperature for the preheating unit (-6°C...+15°C exhaust air).• Changing the setpoints.Max 3 control panels may be in operation. When two or more control panels are used, themost recent control function is the one that is valid.DIGIT SEDSPEEDLiving space (m2 )Living space (m3 /h)Total electricity consumption of the fans (W)LON converterCarbon dioxide sensorControl panelHumidity sensor65 115 162 209 270 306 349 414© VALLOX • We reserve the right to make changes without prior notification.
