HRS Hevac Ltd AquaModule AMB
Installation, Operating & Instruction Manual
1 General information
HRS Hevac AquaModule AMB is a compact tap water system product including a brazed heat exchanger,
motorised control valve and managed primary and secondary pumps, as per versions.
It is equipped with a control box including a dedicated PCB and communicant temperature controller.
Piping is made of specially designed brass parts sealed by flat gaskets for easy maintenance.
AMB has been tested hydraulically and electrically at the factory.
The AMB must be connected to a primary heating source, like a boiler or a heat exchanger. The secondary
side is connected to cold water inlet and to domestic hot water network, see flowcharts for more details.
The tap water module is designed for indoor installation, for example in a plant room. The ambient
temperature in the room must be min 0°C and max 40°C, max humidity 85% without condensation.

DS-Double Primary / Single Secondary
Available pressure on primary side : at least 5 kPa on all models. This pressure results from the difference
between the primary pump head and all the pressure drops (heat exchanger, control valve and piping).
If pressure drop between AMB and heating source is higher than 5 kPa, use either a transfer pump of the
same flow rate as primary pump or a mixing bottle. Please refer to flowcharts in this manual.

Cold water enters at bottom connection (3) and leaves at the required temperature at top connection (4).
The secondary circuit should be equipped with a recirculation or a charging pump,
Modules suitable for 230V 1 phase / 50 Hz + Earth,
Make sure power supply in the field corresponds to the above voltage,
A fuse protection or MCB should be provided on site.

3Installation
The installation work must be carried out by an authorized installation contractor.
The temperature and the pressure of the water are very high. Only qualified technicians
are allowed to work with the Aqua0RGXOH$0%. Incorrect operation may cause serious
personal injury and result in damage to the building.
Minimum pressure/temperature on primary side: 1.0 bar/ 2°C, 1.5 bar / 110°C
Maximum pressure/temperature on primary side :10 bar /110°C
Maximum pressure on secondary side: 10 bar/ 100°C
3.1 Unpacking/Preparation/Mounting
xRinse the pipes, before connecting them to the tap water module.
Pipe works may contain solid particles that could block or prevent the modulating valve to
operate correctly.
xPipe the primary and the secondary of the module.
xFill-up both sides progressively with water.
xPurge air at high parts.
xPurge all the pump bodies.
xSwitch the power on.
xCheck controller setting and enable the required functions.
3.2 Commissioning
Before installation this manual must be read.
The controller has been set at the factory. If any function needs tuning, values can be changed with
reference to this manual for parameter setting. Initially, the commissioning process should be
carried out with the factory settings.

The following changes can be done in end user mode:
xSettings which are identical/different for each day of the week at defined times
xNormal temperature(s)
xLower temperature(s)
xSpecial period of defined duration during the current year
xOne time temperature change at a specific time.
6.1 Set the hot water temperature
Please set a hot water production temperature in line with current national legislation and
recommendations (UTD, Standards EN, ISO etc.)
All countries have different rules for how hot or cold tap water should be.
+56+HYDFrecommends the hot water temperature is at least 55°C and a hot water recirculation
not less than 50°C.
At a temperature below 50°C there is a risk of bacterial growth.
Note that at temperatures above 60°C the risk of scalding increases.
Set points above 63°C result in an increased risk of precipitation of lime scaling on the surfaces of
the heat exchanger.
6.2 Time programs
The time programs used in Aqua0RGXOHare adjusted the same way.
Time programs:
xSP_T_Sec_Outlet, to be found in the menu S1 Menu Secondary Outlet. It is to set the DHW
temperature
xThTr_Activated to be found in Thermal Treatment Menu, to activate a thermal treatment (1
sensor mode).
xMulti_P to be found in 230V Triac menu, to activate the 230V power output on the controller
The time program has two different temperature modes, week-temperature or weekend-
temperature.
Define for each day of the week which mode to use.
By default has the weekend-temperature mode the same settings as the week-temperature mode.
It is even possible to customize the temperature programs with special dates (holidays periods or
free days).
Each temperature mode can have several different times set per day. For each time a different
temperature can be selected that are then in effect until the next time occurs. If only one time is set,
the program will run with the selected temperature.

6.3 Changing time and temperature in a time program
By default, the DHW set point SP_T_Sec_Outlet, set to 60°C by default, at any time, all the days of
the week.
Add extra temperature set points at different times of the day.
These changes will be reported to all days with the time program week, excluding the time program;
weekend.
1. Use the wheel and mark the clock logo. Press the wheel.
2. Mark the day you want to change.Press the wheel.
Now you can choose to:
a) Change a time or temperature.
Mark the line and press the wheel. Change the value by
turning the wheel.
Confirm the new setting by pressing the .
b) Add a new time or set point; choose .
c) To delete a time or set point; choose; .
In this example the set point is 60°C at 22h00.
You can choose to reduce the temperature during the night, in
this example the night temperature is set to 55°C.
6.3.1 Special days
Exception days, so called special days, can be defined. The
calendar in the controller controls the exceptions that can be
selected in the Time program.
Exception days override the weekly schedule.
In the Main screen menu, mark ‘Spcl.Days’ and press the wheel.
Choose between:
xAnnual - holiday periods where you have to specify
beginning date, end date and DHW set point. This mode
is applicable to schools, offices and so on.
xBank Holiday - special days during the year where set
points can be different ex: Christmas, New Year.
xDaily programs - particular days where you want to
change the temperature set point.

6.4 Making a Quick temperature change
You can quickly define a “one time” temperature change, a period of the day with a different setting.
When the change period has expired, the temperature set point goes back to standard time
