GB.XZONE.120522 Function Guide for the GOLD, Xzone 1. General 2. Material Specification The Xzone function is designed for controlling one extra temperature zone via the ventilation system. Sometimes it is necessary to control a part of the ventilation system with different temperature prerequisites. This may be due to proximity to the perimeter wall of the building facing north or south; workshop, office or other conditions that give rise to different temperature loads in various parts of a building. The Xzone function can control one extra temperature zone, max. Xzone can be used for all types of GOLD air handling unit with program version 5.00 or later, and both postheating and cooling can be controlled in the extra zone. When Xzone is activated, several menus appear in the hand-held micro terminal under user level for setting and reading the extra zone parameters. The type of temperature control for the extra zone must be selected separately, and can be of another type than that used in the main zone. If extract air temperature control is selected, the temperature sensors must be positioned so that they will not be influenced by the temperature in the other zone. This means that the internal extract air sensor (inside the air handling unit) must not be used for control for the main zone. The room sensor or extra extract air sensor should be used, (see TBLZ-1-30 or TBLZ-1-24 in section Material Specification). The air heater and air cooler for the main and extra zone must be sized on the basis of separate computerized calculations. Always take into account that the duct system where the air heater and air cooler are fitted, does not have the same dimensions as the connection spigots/ frames of the air handling unit.

Operation The Xzone function requires två IQnomic Plus modules for wiring temperature sensors as well as an air heater for postheating and an air cooler. The wiring of temperature sensors to the IQnomic Plus requires the presence of both modules in the system even if there is only one air heater or one air cooler in the zone. Connect a cable for 0-10 V DC control of valve actuator - heating and cables for control of the pump for the reheater (if any), supply air temperature and freeze protection monitor sensors to the IQnomic Plus module A (function selector switch = A). If an electric air heater is used, connect the overheating protection alarm signal cable to the input of the freeze protection monitor sensor. Connect a cable for 0-10 V DC control of the valve actuator cooling or air cooler for cooling in 1 - 3 steps or cooling pump control and extract air/room air sensors to the IQnomic Plus module B (function selector switch = B). The Xzone for heating and Xzone for cooling must each be activated separately. The type of control signal for the heating and cooling function respectively must be selected individually. Temperature control for the Xzone operates completely separated from the temperature control of the main zone. If an air heater for postheating with freeze protection monitor is selected for the extra zone, the heat retaining function operates completely separately. The heat retaining and alarm limit values preset at service level are applicable to both the extra zone and the main zone. 2 www.swegon.com The cooling min. flow function applies to the flow from the air handling unit, not the flow for each zone. When the total flow reaches below the preset value, cooling will be blocked in both zones. If intermittent night-time operation is activated, the conditions in the main zone are controlled according to the settings of the function. When the air handling uit starts up, the extra zone is controlled according to ordinary temperature control settings. Connect the cable of the air heater for main zone postheating to the ordinary heating output on the GOLD air handling unit control unit. Connect the main zone’s cooling control cables to the ordinary cooling outputs on the GOLD air handling unit control unit. Connect the air heater of the extra zone to the screw connection terminals of the IQnomic Plus module. The heating output cannot have modular connection and if standard coils for GOLD with modular connection are used for the extra zone, the cable will have to be cut. Important! The function with output power reduction (for an electric air heater), activated in the event of low airflows for protecting the heater elements from overheating, is blocked when the Xzone is selected. Since the control system cannot measure the flow in the different zones, the function is blocked both for the extra zone and the main zone. We reserve the right to alter specifications.
