5.0 Functions 5.1 OPERATING MODE There are five main operating modes. The operating In all the operating modes, the supply fan(s) will operate mode determines how the airflow or the fan torque as per the assigned mode and parameters. The exhaust is modulated. - Page 19 5.2 TEMPERATURE CONTROL There are several options available on GLOBAL units to ensure a comfortable temperature. The options are controlled either via supply or extract air temperature. Supply Air Temperature Supply temperature control is the default setting. This involves keeping a constant supply air temperature without consideration to the load in the premises.
- Page 20 5.4 COOLING RECOVERY (RX ONLY) The cooling recovery function uses the lower extract air temperature to cool down the fresh air. The function is not configurable. If there is a cooling load in the building and the temperature in the extract air is lower than the outdoor air temperature, the heat exchanger shall be automatically controlled to operate at maximal speed.

Page 38: Preventive Maintenance
7.0 Preventive maintenance Attention : before handling and/or opening the access panels it is compulsory to shut down the unit and disconnect the power supply using the general switch located on the front panel. Do not isolate the power supply whilst the unit is running. If KWin and\or KWout are installed, then isolate the corresponding power supplies. - Page 39 7.3 EVERY 12 MONTHS 1. For rotary heat exchanger (RX) units, check the brush seals on the rotary heat exchanger along the perimeter in contact with the frame: If necessary, bring the brush seals closer to the exchanger to ensure good sealing. 2.

The fans are stopped for 1 minute. The alarm is configurable through the advanced setup and is disabled by default.
- Page 53 8.20 TYPE 18: ALARM INDICATING AN INCORRECT POSITION OF THE MODULATING BYPASS RELATIVE TO THE ORDERED POSITION - Conditions: • PX units with modulating bypass - Causes: • This alarm indicates that the modulating bypass has not reached the ordered position within 10 seconds. The most common reason for this is a damaged position sensor on the bypass actuator, and this must be replaced.
- Page 54 8.22 TYPE 20: ALARM INDICATING THAT THE DEFROST PROCESS IS ACTIVE - Conditions: • Unit with counter flow heat exchanger - Causes: • The ice forming inside of the plate heat exchanger is genrating a pressure drop that is to high for the current airflow. This detection requires a Modbus pressure sensor placed on the heat exchanger and that the modulation of the fans speed is based on the airflow and not on torque •...
- Page 55 8.23 REC TABLE In the control board the “REC type” is used to define the type unit. When replacing the control board, the REC type needs to be configured in the product setup menu. The product setup menu is used to enable specific features or to modify factory settings. This must be done by an accredited technician.
