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

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.

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.
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.
