12 VEX5 (Everest XH) FUNCTIONS FOR OPTIMAL THERMAL COMFORT Temperature control Air supply temperature Principle The unit is controlled to maintain a constant air supply temperature. Settings: Air supply temperature set point. Equipment supplied with the unit: Air supply temperature sensor supplied already wired into the unit, to be fitted to the aeraulic ductwork. Example of use: This control method will mainly be used when the VEX (Everest) unit is only used for ventilation and not for cooling and/or heating the building. The VEX (Everest) unit ensures a constant air supply temperature defined by a set point close to the temperature required inside the building. Variations in the temperature inside the building are handled by heating and cooling systems independently of the VEX (Everest) unit. Temperature control Exhaust temperature Principle: The unit is controlled to maintain a constant temperature on exhaust air. Settings: The exhaust temperature set point is configured in the User menu; the minimum and maximum air supply temperatures are configured in the Advanced menu. Equipment supplied with the unit: Exhaust air temperature sensor, delivered pre-cabled into the unit. Air supply temperature sensor supplied already wired into the unit, to be fitted to the aeraulic ductwork. Example of use: This method will mainly be used when the VEX (Everest) unit is used for ventilation, cooling and/or heating the building. By adjusting the exhaust temperature you can adjust the ambient temperature. These settings therefore take into account any increases/decreases in temperature (opening a window, sunlight on windows) and adapts the cooling/heating provided by the VEX (Everest) unit accordingly. Temperature difference between exhaust air and air supply Principle: The unit is controlled to maintain a constant temperature differential between the air supply and exhaust air. Settings: The differential setting between the air supply and exhaust air is configured in the User menu; the minimum and maximum air supply temperatures are configured in the Advanced menu. Equipment supplied with the unit: Exhaust air temperature sensor, delivered pre-cabled into the unit. Air supply temperature sensor supplied already wired into the unit, to be fitted to the aeraulic ductwork. Example of use: This setting method will principally be employed when the building is fitted with a separate heating system. The air supply temperature varies with the exhaust air temperature, which in turn is related to the independent heating/cooling systems. The Everest unit is therefore slaved to the external systems. Bypass control Free cooling - Night cooling Principle: Free cooling & Night cooling involve bypassing the heat exchanger in order to use the outdoor temperature to cool the building, free of charge, during the summer. Free cooling is used to provide cooling while the unit is running. Night cooling activates the free cooling function when the fans are stopped. Operation: VEX (Everest) units are fitted with an adjustable 1% bypass. Depending on the temperature, the control system adjusts the opening of the bypass dampers to achieve the pre-set air supply temperature. When the night cooling function is activated, the fans operate in over-ventilation mode (configurable). Settings: The bypass is opened according to the temperature of the exhaust air / outside air / air supply set point / timer programming. A contact is available to opening the VAV variable airflow units in night cooling mode. 12

13 VEX5 (EVEREST XH) Heat exchanger frost protection The heat exchanger plates cause condensation on the outlet. If this condensation occurs at a low temperature, the water can freeze and ice-up the exchanger. This risk of freezing occurs whenever exhaust temperature drops below 5 C (configurable value). The VEX (Everest) unit has two methods of frost protection: - by controlling the bypass, - by controlling the bypass and an electrical coil on the exhaust outlet. Smart frost protection via bypass control Principle: This frost protection method involves bypassing some of the exterior air to avoid overcooling the discharged air. Description: The use of a bypass reduces the fresh air inflow to the exchanger, thereby reducing the exchange of heat and preventing overcooling of the discharged air. The opening of the bypass is adjusted to assure a discharge air temperature > 5 C (configurable value). The airflow that bypasses the heat exchanger is routed directly to the air supply outlet, thereby maintaining the inflow rate. Example: Outside temperature = -1 C No frost protection: With frost protection using bypass control: -1 C Discharge temperature = 1 C => risk of freezing 2 C -1 C 75% of airflow 25% of airflow 2 C -1 C 1.4 C FROST 17 C 5 C NO FROST 18.5 C 11 C Smart frost protection via bypass control + an electrical coil. Principle: This frost-protection method involves: - heating the exhaust air using an internal electrical coil to prevent ice forming on the discharge, - bypassing some of the fresh air to maintain a comfortable air supply temperature. Description Heating the exhaust air ensures the air discharged is > 5 C and prevents ice forming on the exchanger. Bypass opening is adjusted to lower the air supply temperature, mixing the air supply from the heat exchanger with the cold outside air that has bypassed the exchanger. The air supply temperature set point is therefore respected. Example: Outdoor temperature = -1 C Air supply temperature set point to ensure frost protection = 19 C Discharge temperature = 1 C => risk of frost. The coil is activated so that the discharge temperature > 5 C. On inflow, the outdoor air is by-passed to obtain the required air supply temperature. With frost protection using bypass control: With coil frost-protection: 3% of airflow -1 C 2 C -1 C 7% of airflow 33 C kw 2 C -1 C 1.4 C 17 C 17 C No risk of frost as discharge temperature > 5 C 31.5 C 19 C Temperature set point reached 13

14 VEX5 (Everest XH) Damper control Principle: The dampers are used to prevent the circulation of air inside the unit when it is stopped. The dampers are motorised and they operate in conjunction with the fans. The damper servomotor is fitted with a return spring, allowing the damper to close if there is an electricity blackout. Coil control Principle: The Aldes Smart Control system controls the coils directly. Operation: The electrical coil is activated proportionally by a -1V signal transmitted by the control system. Equipment supplied with the unit: Coil built into the unit, pre-cabled and ready for connection to the power supply. UNIT MONITORING FUNCTIONS General information: The Aldes Smart Control system provides a multitude of possible methods for controlling the unit. Water coil Principle: The Aldes Smart Control system operates the valve. Operation: The valve is controlled proportionally by a -1V signal transmitted by the control system. The water coil is supplied with a temperature sensor to be fitted into the water return circuit. Depending on the temperature of the returning water, the control system will activate the coil frost-protection function: valve opened to maximum. In the event of an extreme temperature, the control system will shut down the fans. Equipment supplied with the unit: Coil delivered built into the unit. 3-way valve, servo motor and frost protection sensor supplied, for installation on site. Fire alarm An external contact is available to set the unit to 'fire' mode. This enables a dedicated control mode (e.g. unit shutdown), when a fire alarm is transmitted to the Aldes Smart Control System. Backup Reset to factory settings. Save to a PC or SD Card, the control parameters used when installing the equipment.

With this system we can instantly see the filter clogging level, as opposed to a simple pressure switch, which is only triggered when the filter is totally clogged. The fitter defines a threshold pressure loss level, upon which the unit will transmit a 'change filter' warning message. The clogging threshold level can either be a pressure loss level (e.g.: 6 Pa) or a maximum percentage of rise in pressure loss compared to the new filter levels (e.g.: 5%).
