User Interface

The user interface, built into the PCB, consists of the following
devices.

Indicator LED

The various functions and faults are signalled by either 
flashing or permanent illumination of the LEDs.

Energy meter installation

The HIU is designed to include a compact energy meter with
integral return probe, with 1” threaded connections and 130 mm
overall body length.

Before carrying out any maintenance, repair or part replacement
work, proceed as follows:

turn off the electric supply

close the isolation valves

drain the HIU using the drain cocks provided

remove the spool piece (6)

remove the blanking plug

install the flow probe in the ¼    ” pocket provided (5)

install the flow meter on the return pipe.

Please refer to the heat meter technical data sheets for further
information.

Electronic controller

Operating Principle

All functions offered by SATK102 HIUs are controlled by a digital
controller.

The  controller  is  factory  set  with  different  parameters  and
settings depending on the model.

There are a number of specific DIP SWITCHES on the controller
circuit board; the way these are configured will determine the
functions enabled.

Automatic controller function

Reset mixing/modulating valve to zero

Immediately after the power supply has been switched on, the
position of the mixing/modulating valve is reset to zero.

Pump anti-clog

When the pump is not in use, it is powered on for a period of 5
seconds every 24 hours.

Mixing valve/modulating valve anti-clog

The anti-clogging cycle for the mixing/modulating valve is run
every 24 hours.

Trimmers for set point settings

These allow the temperature of the domestic hot water cycle
to be set and their values will be displayed on the LCD display.

LCD display

The set domestic hot water temperature and error codes are
displayed.

Dip switches

Dip switches allow the setup of the various models and
optional functions to be activated.
