With this option, an air flow rate controller must be selected if the unit does not incorporate a supply air plug fan. However, if the unit incorporates a supply air plug fan, it is not possible to select the air flow rate controller option, since the fan itself will perform this action. Note: the differential pressostat for control of air flow is included with centrifugal fan (optional).
It is recommended that a droplet eliminator is installed on the indoor coil from the following air flow rates: SPACE PF (m3/h) 415 27 700 420 30 090 480 27 700 485 30 090 540 30 090 600 30 090 650 37 030 720 37 030 840 37 030 960 37 030 1100 1200
included as standard
Note: under operating conditions with a high level of dehumidification in the indoor coil (for example on installations close to the seafront), it may be necessary to install an eliminator even if the flow rate is less than that given above. With a hot water coil, it is not possible to fit the droplet eliminator.
Propane or natural gas burner with 0-10 V proportional actuator. Condensation boiler, with pre-mixing and modulation technology, used to achieve efficiency levels of 105% of the lower heating value (LHV). The electronic control manages its connection in heating mode, via an ON/OFF signal. On cooling-only units, the control activates the burner in the same way as a backup electrical heater stage. On heat pump units, it is possible to select three different operating modes: - As backup for the compressors, as a backup electrical heater stage. - In place of the compressors. - In place of the compressors beyond a selected outdoor temperature. Power control is carried out by the burner's own control, according to the signal received from the CIATrtc control (0-10 V). Important: with a gas burner, a differential pressure switch for controlling the air flow is compulsory. If the unit incorporates an EC supply air plug fan, the air flow is controlled directly through the plug fan. It is also recommended to have fouled filter detection and antifreeze protection options for the components of the electrical cabinet of the outdoor temperature are low (compulsory if the outdoor temperature is below -8ºC WB). Important: With this option, CIATrtc electronic control is mandatory, the change of control isn’t allowed.
Available on all the models, except 415 and 480. Not available on assemblies with upper supply air.
