Safety Instructions
This device has been designed according to all up to date specifications and fulfills the necessary regulations in order to be safely
operable for many years. During the design and construction phase has been taken into account every existing directive for such
kind of equipment. You are kindly advised prior to installation and operation to consult this guide. Be sure you realize every
consequence of your action and take all necessary precautions. If you don’t understand something do not hesitate to contact t he
manufacturer directly and take the advice of our technical personnel.
Installation must be carried out from experienced authorized electrician.
Do not open the plastic enclosure for any reason. Such action has danger of electric shock and nullifies the warranty.
This device can be used as control device but never as safety device of an installation.
Do not use the device for any other purpose except of those that has been designed for i.e. solar systems control.
Do not use the device for life critical applications.
This device is not water resistant. Install it in an indoor place away from rain, humidity and extreme weather conditions.
This device is not a measuring instrument.
Do not exceed the maximum limitations as referred below for any reason.
! ATTENTION During its operation the device keeps record for various operating information. The manufacturer maintains the
right of using such information if for any reason the device will be returned to the factory.
! ATTENTION The manufacturer has no liability if possible damage might be induced by the device during its operation to
installations or systems or other devices that is cooperated or connected with or even control them as well as to the place in
which has been installed.
! ATTENTION Technical characteristics, capabilities and operation of the device as described at the present manual can be
modified without prior notice.
! ATTENTION Figures shown are for indicative purposes only. Integration engineer is exclusively responsible for designing and
interconnecting the whole system devices according to the required needs of each application.
Installation
The device can be installed in “Ω” shaped type of rail or directly to the wall. Select carefully the place for installation in order to
avoid moisture. Reserve enough space for cables to pass through. A gap of 5 mm is recommended around the device for better
ventilation. During the installation interrupt mains supply. Choose cables of suitable cross-section and insulation according to the
applied current and voltage. The device is equipped with appropriate cable terminal clamps for easy and safe connection. Do not
over tighten the screws. Study carefully the electrical connection diagram of Figures 1.
! ATTENTION Terminals (9,10), (11,12) and (13,14) constitute the “dry” contacts of the solar pump, the burner relay and the
recirculation pump relay respectively. If you need to drive mains operated pumps and burner you have first to make the
necessary connection between No10, No12, No14 and No16 terminals.
! ATTENTION The S1 temperature sensor must be of KS30-1K0 type while the S2, S3, S4 of RS301K5 type. Insert the probes into
correct diameter sockets for better temperature reading response and improved accuracy. Place the probes according to the
Figure 1. The maximum distance between probe and device must not exceed 30m. The connection must be done with
conventional thready two-conductor cable with cross section i.e. 0.5 mm to 1 mm.
! ATTENTION Use separate cables for probe and load or supply connections. Mixing low-level signal probe cables and load or
supply cables affects devices performance.
After the installation completion replace the front cover of the electric enclosure and ensure that when the device is operable
only the front touch panel is user accessible.
Setup
The device contains luminous display in which parameters and messages are displayed. It also contains three light indicators
colored red, yellow and green as well as three touch buttons.
By pressing momentarily button “POWER” the device toggles between ACTIVE and INACTIVE state while at the same time shows
the message “On” and “Off”respectively. Display shows the temperature which is defined by parameter diS the meaning of which
will be explained below.
Stored parameter values can be altered from the two offered menus. When the “”button is momentarily pressed the forst
menu is activated. The “”key press activates the second menu.
The yellow indicator lights on as an indication of setup process. Display will show the first parameter name of each menu. Use
“” and “” keys to navigate through the parameters of each menu. When the name of the parameter who needs modification is
shown then press “POWER” key. Display shows the value of that parameter flashing. . Use “” and “” keys to modify the value
according to your needs. The newly entered value will be automaticaly stored or by pressing again the “POWER” key. When
parameter modification is complete then navigate through the menu options to “End” and select it by pressing “POWER” key. This
action terminates the setup session and returns to the normal operation mode.
MENU 1 Change the values of the following parameters:
MENU 2 Change the values of the following parameters:
