ELECTRIC RESISTANCESThe electric resistance operating mode is defined by the following parameters:P27 ModeRes = 0 integration element (ventilation forced at max.)1 main element (manual or automatic ventilation)P53 OutResType = 1 single-phase2 two-phase3 0 – 10 voltINTEGRATIONONOFFP01P01Set PointMAIN ELEMENTONOFFP01Set PointThe water valve is opened when thermoregulationis demanded:if the probe detects hot water, the resistorsautomatically become an integration body.On the contrary, if after TimeValve is over,water temperature is not suitable, the valvecloses, the H2O alarm is not activated and theresistors are not activated.As soon as the probe detects that watertemperature > MinH2oHeat, resistors becomeintegration bodies and the valve opens.In this mode, the water temperature alarm isnot managed.ONSINGLE-PHASERESISTANCESOFFP01Set PointTWO-PHASERESISTANCESP01Set PointDEHUMIDIFICATIONThe dehumidification control is managed by the network, which is an upwards system that uses one or more terminal units todehumidify.When the DeumiOn network variable is switched on 1, the unit is forced into cooling mode, even when the temperature set ismet (100% opened valve and minimum ventilation speed).This occurs to meet the humidity conditions decided by the network (detecting the relevant humidity by a room thermostat).The dehumidification process shown by the display is stopped when the following occurs:• the DeumiOn variable is 0 (humidity conditions are met).• <strong>Temp</strong>erature is below the LowLimit, value; therefore, the process can start again only if ambient temperature > setpoint<strong>Temp</strong> and if there is still a demand.The dehumidification process can not start if:• The operation mode is the Heating mode.• The unit is OFF.CONTROL (FOR UNITS WITH 3 SPEED BOARD)See ELECTRICAL CONNECTIONS sectionM23740N6-03 01/10/07 page 28
ROUTINE MAINTENANCEBEFORE UNDERTAKING ANY SORT OF MAINTENANCE OR CLEANING, DISCONNECT THE ELECTRICAL POWERSUPPLY TO THE UNIT, AND ENSURE THAT OTHER PEOPLE CANNOT RE-CONNECT IT .All equipment is subjected to wear out.The maintenance makes :1. keeps the unit efficiency2. the components last longer3. keeps their efficiency and limits breakdownsTherefore, it is fundamental to perform periodical checks: afew controls can be performed by the user(AUTONOMOUS MAINTENANCE) and they are mainlycleaning activities; otherwise, controls have to beperformed by specialized technicians (INSPECTIONS).The machine should have a log book used to keep track ofthe performed controls. This will make fixing upbreakdowns easier.Take note of the date, type of control (autonomousmaintenance, inspection or fixing up), description of thecontrol, actions taken and so on.Parts subject to intervention:• AIR FILTERS• CONDENSATE DISCHARGE• ROOM AIR TREATMENT COIL• STRUCTURESERVICES• EXTERNAL FANS• DUCTING• FANS WITH BELT DRIVE• ELECTRIC ELEMENTSIt is very important for the air treatment coil to be able tooffer maximum thermal exchange. Therefore, the unit mustalways operate with the filters installed and clean.Cleaning and replacement of filters are very important interms of health and hygiene.Operation with clogged filters leads to a reduction in the airflow rate, resulting in malfunctions and unit shutdowns. Itmay even cause the unit to break down.AIR FILTERSHow often the filters need to be checked depends on thequality of outdoor air, unit operating hours, dust andnumber of persons in the rooms.As a guideline, cleaning should ideally take place betweenweekly and monthly. It is advisable to start with frequentchecks, and to adjust the frequency based on how muchdirt is discovered.PLEATED FILTERS1. Remove the closing doors2. Carefully extract the filter so that no dust reaches theparts below3. Wash the filtering mattress in warm water with acommon detergent.4. Carefully rinse it under water while preventing to pourwater in the room5. Dry the filter6. Reinsert it to its seat7. Reassemble the closing doorsOld filters, washing residuals and residual parts must bedisposed of, according to the law in force.CONDENSATE DISCHARGEDust and deposits could cause obstructions.Clean the tank, pour some water into the tank and check water flows normally.M23740N6-03 01/10/07 page 29
