together with the unit: - Directions for assembly and use - CTS 602 directions (this document) - Electrical chart The purpose of this manual is to clearly show the menus and possibilities of the CTS 602 control. This manual may describe functions that are not accessible in your unit. The directions can be used for all types of units described in figure 1 page 4. May be subject to change page 3 af 26 Review of the thermometer sensors Figure 1: Thermometer sensors Explanation for figure 2: T1 - is the thermometer sensor for the fresh air and should be placed at the north side of the building. T2 - is the thermometer sensor for the inlet air(without heating surface). T5 - shows the temperature of the condenser. T6 - shows the temperature of the evaporator. T7 - is the thermometer sensor for the inlet air after a heating surface. T10 - is the thermometer sensor for the exhaust air in a room (accessory). T15 - is the thermometer sensor in the CTS 602 panel. The temperature of the sensors can be read in the “Show data” menu. May be subject to change page 4 af 26 CTS 602 panel Use of the CTS602 panel: - press ESC to go one step back in the menu - press qpto move up or down in a menu or to adjust an activated menu - press ENTER to activate a menu - press ENTER to confirm a menu - press OFF to turn off the unit - press ON to turn the unit on Figure 3: CTS 602 panel The following is indicated by the light-emitting diode at the front of the CTS 602 panel: Constant yellow light: the compressor is in operation Flashing yellow: the unit is in alarm condition The panel can show 2 lines of text with each 8 characters. The upper line shows a guiding text. The bottom line shows the matching values to the guiding text. The text in the display in “on” as long as there is power to the unit and will not turn off even though the unit is set to “off” or has not been operated for a longer period of time. How to use the menu: It is possible to adjust a value or a function by finding the matching menu via p or q. To activate the desired menu press ENTER. To adjust the settings of the value press ENTER until the value flashes. The adjustment can now be done viapq. To save the chosen value press ENTER. It is advisable to have the panel and/or the review of the menus near by during the reading of the menus. If none of the press buttons are activated for one minute the control will automatically return to the main menu.
