Product descriPtion
Thermal Management Unit
General Description
AIC’s Thermal Management Unit is an appliance,
which consist of two major elements. Master con-
troller of hybrid system and a stratication buffer
tank. Both of these elements form one unit in a
build casing. Controller’s task is to deliver most op-
timized heat delivery for Central Heating and Hot
Water purposes, using Heat Pump and a Boiler as
heat sources.
Stratication buffer tank is specially designed to hy-
draulicly connect both heat sources and form one
system. Unique composition of connections and
bafe allow to create heat without interfering main
or supplementary source, extending efciency of
the system.
Safety Devices
The TMU appliances are equipped with two water
sensors: a top and a bottom temperature sensor,
that provide safety for your appliance and water
circuit.
The TMU appliances are not provided with the fol-
lowing mandatory safety equipment that the install-
er must place in the system, in accordance with the
applicable local standards and regulations:
îA safety group and manometer.
Optional equipment
Some optional equipment can be used with the
TMU. Please contact your AIC representative for
more information and a list of available equipment.
To lengthen the life of your appliance and heating
system, the following equipment can be installed in
the circuit:
îWater lter
îDirt separator
Product descrIPtIon
The components of the appliance were manufac-
tured in accordance with the requirements of EU
regulations.
The stratication buffer tank is designed and man-
ufactured in accordance with the sound engineer-
ing practice (Article 4.3 of the Pressure Equipment
Directive 2014/68/EU).
For conformity of the Controller, refer to Declaration
of Conformity no. 2021/20EU/01.
The Declaration of Conformity is available on re-
quest from the AIC representative.

connected to the appliance.
2. Push the On/Off switch located on the right
side of the appliance.
When in the ON position, the switch
remains pushed in and is illuminated.
Follow-on tasks:
Check the pressure of the water circuit in operation. It
should be between 0,8 and 6 bar.
i
i
Stopping the Appliance
Conditions:
None
Procedure:
1. Push the On/Off switch located on the right
side of the appliance.
When in the OFF position, the switch
is released from its pushed in position.
Its built-in light goes o and the button
comes ush with the outer frame.
2. To completely cut the power supply to the
appliance, either disconnect the power sup-
ply cable from the appliance, or use the ex-
ternal circuit breaker.
Follow-on tasks:
None
i
To remove an error code from the display temporarily and go back to the Home screen, de-
press the rotary selector for more than 3 seconds.
i
These are the most common tank errors. For errors aecting the entire Hybridos system,
refer to “Error Codes and Solutions”on page G-59.
i
After stopping the operation of the tank on the control panel, all Hybridos system
components are turned o. They remain in stand-by mode. It is not possible to turn
o the tank while leaving the boiler and heat pump running.

ing a function.
îDepressing the selector (short push) allows to
select a function/value and validate a choice.
îDepressing the selector for more than 3 sec.
when an error is displayed on the screen, takes
you back to the Home screen. Doing the same
in Expert menus brings back to the Expert view
start page.
When entering a menu/sub-menu, the slow
rotation of the selector to the right (clock-
wise) allows to scroll through the menu,
down to the last function. Turning the selec-
tor to the left (counter-clockwise) allows to
scroll up to the rst function of the menu.
i
All functions of the controller are described in these operating instructions. Some functions
require optional accessories. These functions are not specically marked. If you have any
