The interface consists of two distinct parts: the main interface (left-hand section) and the summary interface (right-hand section). The summary interface (right hand section) includes a mimic diagram of the unit, together with push-buttons and LEDs. It gives quick access to the main operating parameters of the unit.
SUMMARY INTERFACE LEDs. INDICATION WHEN LIT Green LED: The unit is authorised to start or is already running Red LED: - Lit: circuit A or unit shut down by alarm - Flashing: circuit A or unit running with alarm present. CHANGING THE OPERATING TYPE BUTTON ACTION Continually press the operating type selection button for more than 4 seconds. Hold down the Start/Stop button. The available operating types are displayed one by one until the button is released.
Release the Start/Stop button if the operating type you want is displayed (in this example L-On). 4.3.4 - Expand display Pressing the Enter button causes a 23 character text expansion to be scrolled across the four-digit display. All user menus provide an expansion of the current displayed parameters.
If the expansion is complete the four-digit display reverts to item value. MENU STRUCTURE. Menu tree structure MENU. INFORMATION MENU (3) ITEM FORMAT UNITS DESCRIPTION Automatic display mode.

The following table summarises the possible selections depending on the control types (local, remote or CCN) and the following parameters: Setpoint select in local control: item #12 of the Infor- mation menu permits selection of the active setpoint, if the unit is in local operating type. Heating/cooling operating mode Control contacts: status of control contacts 5 and 6 (dual- circuit units only).
Reset means that the active setpoint is modified so that less machine capacity is required (in cooling mode, the setpoint is increased, in heating mode it is decreased). This modification is in general a reaction to a drop in the load. For the Pro-Dialog control system, the source of the reset can be configured in the User 1 configuration: it can be provided either by the outdoor temperature (that gives a measure of the load trends for the. 5.11 - Defrost function Defrost is activated, when the unit is in heating mode, in order to reduce frost build-up on the air heat exchanger.
The defrost cycle can only be applied to one circuit at a time. During the defrost cycle the fans of that circuit are stopped, and the four- way refrigerant valve is reversed, forcing the circuit to cooling mode. 6 - DIAGNOSTICS - TROUBLESHOOTING 6.1 - General The PRO-DIALOG control system has many fault tracing aid functions. The local interface and its various menus give access to all unit operating conditions. The test function makes it possible to run a quick test of all devices on the unit.
If an operating fault is detected, an alarm is activated and an alarm code is stored in the Alarm menu.
