Description

The KTD control unit is used to programme and control a solar thermal systems. Two different versions are available, KTD3 and KTD5, which are used in combination with R586S, R586S-0 and R586S-1 circulation groups. The control unit is user-friendly thanks to its backlight graphic display, four buttons, handy programming assistant and on-line help pages. The KTD control unit has inputs for temperature probes type Pt1000, a relay output for controlling an electronic circulator, and one or two relay outputs for commanding a electronic circulator (predisposition for commanding circulator by PWM or 0-10 V signal) and one or two relay outputs for other additional functions. The programs on the control unit allows to set various system configurations. Operation control functions range from the mere reading of the current measured values to long-term system monitoring and analysis by means of charts and statistics. Numerous other functions complete the possibilities offered by the KTD control unit:

• at any time, you can reset the previous values or, if necessary, the manufacturer's default values;
• the menu locking function prevents any unwanted modification of the operating parameters set during the unit programming phase;
• the anti-lockout function activates the pump or valve connected to the relay for 5 seconds, at regular intervals, to prevent any possible lockout due to a lengthy period of non-use;
• the anti-legionella function heats the boiler to a high temperature at fixed time intervals. The KTD allows also to view the thermal energy level produced by the solar thermal system thanks to the setting of certain additional parameters (e.g. glycol type and percentage, and system flow rate).

Warning. The following illustrations should be viewed only as schematic diagrams showing the respective hydraulic systems, and do not claim to be complete. The controller does not replace safety devices under any circumstances. Depending on the specific application, additional system components and safety components may be mandatory, such as check valves, non-return valves, safety temperature liwithers, scalding protectors, etc., and must therefore be provided.

For other possible applications refer to the instruction manual. Signal and command elements The user interface of the KTD control unit consists of a graphic display, a signalling LED and 4 buttons. The dot matrix display (1) indicates the operation of the KTD control unit via text and graphics. The signalling LED (2) is multi-colour and can assume the following status conditions:

• fixed green light if a relay is activated
• fixed red light if “OFF” mode is selected
• slow red flashing in “manual” mode
• fast red flashing if there is an error. Using the 4 buttons (3, 4), you can access the various functions of the control unit. The “esc” button (3) is used to enter or quit the menu; when it is pressed, the control unit asks for confirmation that the modifications must be stored. The function of each of the other three buttons (4) is shown in the row of the display just above the buttons themselves The right-hand button is only used to choose and confirm a function. Examples of the button functions: Button Function +/- increase/reduce a value ▼/▲ scroll up/down through the menu yes/no confirm/refuse Info more information Back go backwards ok confirm your choice Confirm confirm the setting Meaning of the symbols on the display: Symbol Meaning Circolator (the symbol rotates if the circulator is working) Valve (in black is indicated the flow direction) Solar panel Boiler or accumulator Swimming pool Temperature probe Heat exchanger Attention / Error message New information
