  • Page 10 Rotary heat exchanger - Principle / Construction The construction of the rotating heat exchanger used into the CAD O Integral consists of alternating layers of flat and corrugated aluminum foil, which form a spiral from the center. This results in a defined structure of small triangular flutes. Supply and exhaust air each pass through half of the wheel in counter flow direc- tions. The rotor exchanger is a rotating transfer media. It temporarily takes up the heat from the warm air stream and releases it in the colder air stream.

  • Page 57: Airflow Control Fan

    8.1 Airflow control Fan Airflow management can be carried out according to 3 control modes: CAV, VAV, COP. Whatever mode is selected, each fan suction pavilion (extraction and supply) is equipped with a pressure tap and connected to a pressure sensor. The flow rates resulting from the pressure measurements are calculated by the regulator, according to a coefficient K specific to each fan. • The DO1 digital output corresponds to the supply fan running command and can be used for acces- sory operation linked to the operating status of the fans (for example starting a DX unit if the supply fan is running). • Analog output AO4 corresponds to the 0-10V control signal sent to the supply fan. •...
  • Page 58 The air flow will automatically change between these two rates depending on the signal received. Independently, a BOOST (extra m /h) airflow can be programmed in the form of a fixed airflow for extrac- tion and supply. • Digital input DI5 = Start/stop. • Digital input DI6 = forcing GV - forcing of the max flow rate set for the max signal. • BOOST (extra m3/h) selection can be done from the remote control. To perform a BOOST forcing via a digital input, it is necessary to reparametrize a digital input (DI1 for example) and assign it the "Additional alarm 7" function. When closing this digital input, an “External BOOST forcing” message will appear on the main screen. • A fourth flow set point for "night free cooling” overventilation can be entered via the remote control, in the form of an offset of the high-speed flow GV (see free cooling for operation) 8.1.3 Operation at constant pressure COP on extraction or supply mode Recommended mode in multi-zone configuration associated with terminal airflow modulation systems.

  • Page 59: Temperature Control

    8.2 Temperature control 8.2.1 General principle The temperature set point as well as the temperature regulation mode are entered via the touch screen. The supply or ambient temperature is maintained at the set value by acting on the controller outputs (hea- ting/exchange/cooling), a single PI loop is used. The exchanger is considered to be the first potential source of heat or cooling even before the batteries. For CAD O INTEGRAL fitted with a standard rotary heat exchanger (1 speed), the wheel is controlled in binary mode (on or off). For CAD O INTEGRAL equipped with a sorption exchanger, the rotation speed is variable, proportional to a 0 - 10V signal.

  • Page 60 8.2.2 Temperature control modes The temperature regulation can be carried out according to the following 4 modes: • Supply air control at constant temperature The supply air temperature is maintained at the set value by acting on the exchanger outputs, hot output and cold output. The setpoint is adjusted using the display and number keys. The user set point for the mode is entered in °C in the settings menu. • Supply air control at constant temperature with outdoor temperature compensation The supply air temperature setpoint is adjusted according to the outside temperature according to a compensation law made up of 8 factory preset setpoints. The supply temperature is maintained at the set value by acting on the exchanger, internal coil, exchan- ger, external coil outputs.

Depending on the am- bient pollution, and despite the filtration, dust may settle on the battery. After disassembly, the coil can be cleaned with a jet of water, steam or compressed air, proceed with care not to damage the fins of the coil. For units fitted with reversible cooling coils (ER), clean the condensate pan with water and a non-abrasive detergent. Check for proper drainage and check the siphon. 13.8 CORRIGO PLC battery replacement When the low battery alarm appears and the red indicator light turns on, it means that the backup battery for memory backup and real-time clock is too weak. The procedure for changing the battery is described below. A capacitor saves the memory and keeps the clock running for about 10 minutes after the power is turned off. If changing the battery takes less than 10 minutes, there is no need to reload the program and the clock continues to operate normally.
