C-PRO KILO AHU APPLICATION MANUAL A fan operating manually is nevertheless sensitive to eventual alarms, in this case the status will be that of Alarm. 6.5.6 Security inputs You must manage the security of the “thermal fan” for both fans that have been configured. In order to enable the alarm you must set from the constructor Menu the positions in which the digital inputs will be connected for the security evaluations (Hd05, Hd07).
C-PRO KILO AHU APPLICATION MANUAL 6.6 Main regulations The application wants to maintan comfortable conditions within the internal ambient; in order to achieve this the two main regulations are made on two fundamental units of measurement: temperature and humidity. Both regulations provide a Neutral Zone (parameter Pb03 for the temperature and PU02 for the humidity) in which there is no requested regulation.
C-PRO KILO AHU APPLICATION MANUAL 6.7 Cooling and Heating Regulations When the primary regulation is made on the valve (PG04=1) it is possible to manage and to regulate the command for the cooling /heating valve. The regulation comes on a flowing Set Point calculated as shifting from the regulation ambient temperature Set Point. The valve is commanded using a proportional algorithm (P), or a proportional integral (PI). The reference probe is that of the delivery temperature. Note.
C-PRO KILO AHU APPLICATION MANUAL 6.7.2 Valve module regulation In order to utilize it is necessary to set the position (at greater than zero) of the analogue outputs in the constructor menu using the HA05 parameter (cooling valve) and HA04 (heating valve). If HA05=0 and HA04=0 the indicator is not enabled on any of the analogue outputs. In order to utilize only a proportional regulation you need to only set the integral time to zero (Pb02=0).
C-PRO KILO AHU APPLICATION MANUAL 6.8 Post-Heating This may be performed using one coil (PG01=3) or, alternatively, utilizing electrical resistances (PG14>0). The post-heating serves two main purposes: integration of heat in heating or compensation in the dehumidification phase in order to realize the amount of heat lost (i.e. drop in temperature) during dehumidification.
C-PRO KILO AHU APPLICATION MANUAL SetPoint - Delivery 3° resistance 2° resistance Neutral Zone 1° resistance Pb01 x 2 T. Delivery Within each insertion/removal of resistances a certain amount of time (parameter Pb20) must elapse in order to avoid simultaneous occurrences. Using the Hd13 parameter it is possible to enable the thermal alarm of the resistance, which provides for the immediate shutdown of the device. Note.
C-PRO KILO AHU APPLICATION MANUAL 6.9 Dehumidification In order to adjust the comfort of the ambient it is necessary to also consider the humidity in the air and regulate it based on a determined desired Set Point percentage (PU01) and at a neutral zone (PU02) in which the humidity conditions are acceptable and do not require any intervention. The regulation of the dehumidification is proportional-integral, to render it only proportional you need to only set the integral time to zero (PU04=0).

C-PRO KILO AHU APPLICATION MANUAL 6.11.5 Air quality control The external air shutter may be used to replace the air upon request by the appropriate probe (VOC/CO2). It is necessary to enable the parameter PS02=1, and the regulation probe for the air quality (PH46>0). The external air shutter can be commanded based on the regulation probe at set point (PS20) and at the relative differential (PS21). Note. If the air quality probe is in error the regulation is inhibited. The probe can be one of two types: 4.
C-PRO KILO AHU APPLICATION MANUAL 6.11.7 Shutter status In the user interface you can identify the operating status of the shutters which will present you with one of the following: 1. Disabled: the shutter is not managed by the controller. In the user interface you will see the symbol “ - ” when in this state. 2. Closed: the shutter is closed.

C-PRO KILO AHU APPLICATION MANUAL After the delay Pr05 the by-pass shutter will activate in oder to allow for defrosting. When the temperature rises above the allowable value the shutter will deactivate while the recuperator restarts. Note. It is necessary to set the position of the digital output of the recuperators by-pass shutter using the parameter dedicated to the recuperator, Hr01. When the regulation probes are in error this function is disabled. 6.12.
C-PRO KILO AHU APPLICATION MANUAL Note. It is necessary to set the position of the digital output of the recuperator, using the dedicated parameter, Hr01.

C-PRO KILO AHU APPLICATION MANUAL 6.13 Heating/Cooling Pumps A simple method for managing the two circulation pumps (for heating/cooling) is provided. In order to enable the cooling pump you need to set paramater PG10 to 1. To enable the heating pump you will need to set parameter PG11 to 1 in the Consructor menu. Based on the requirement you may choose between two regulations by going to parameter PP01 (continuous regulation, On/Off regulation).
C-PRO KILO AHU APPLICATION MANUAL 6.13.3 Pump status Both pumps may assume any of the following operating states: 7. Disabled: the pump is not managed by the controller. In the user interface you will see the symbol “ - ” when in this state. 8. Off: the pump is off. In the user interface you will see written “OFF” when in this state. 9. Waiting for shutdown: the pump is in the process of shutting down, and is in queue for scheduled protection.
C-PRO KILO AHU APPLICATION MANUAL 6.14 Unit at single coil (seasonal) In this type of unit (PG01=1) there is only one dedicated valve for heating and cooling and, if enabled, there is a single circulation pump; the operating mode (parameter MOdE) determines which behavior to utilize. In the same way all the regulations (fans, freecooling/free-heating, regulations of set-point, alarms, etc..) are distinguished based on the operating mode.
C-PRO KILO AHU APPLICATION MANUAL 6.15 Management (various) 6.15.1 Single or distinct Set Point It is possible to manage a single regulation Set Point for summer/winter, or to set two different ones. If the parameter PH27 Enables the single/distinct Set Point is set to 1 the Set Point is singular (only one parameter), otherwise the Set Point is distinct (two distinct parameters: SEtH and SEtC).
C-PRO KILO AHU APPLICATION MANUAL is possible to set the logic for the Digital inputs by setting the parameter PH50: 0=NO (Normally open), 1=NC (Normally closed). In order to enable this function you will need to enable parameter PH25 Enable variation Set Point from Digital inputs and set the position on which the related Digital inputs will be connected (parameter Hd03).
