ACD10 Constant Temperature Controller
Warnings
Check the controller and its packaging carefully. If you see visible damage
to the controller, do not use it. Installing a damaged product can be life-
threatening.
When adjusting the controller, pay attention to the correct opening direction
of the valve. Wrong turning direction can lead to high or low temperatures in
the system and consequently damage to the system. When adjusting the
controller, make sure you set the minimum and maximum value of requested
temperatures correctly. Incorrectly
selected limit values for setting the requested temperature lead to a wrong
setup of requested temperature and, consequently, undesirable operation and/or
damage to the system and user.
If the controller is installed in an environment where flooding or contact
with water is possible, it shall be mounted above a possible water level or
away from sources of water, so that it is not exposed to standing or dripping
water. Contact of the controller with water can damage the controller and the
person who is in contact with it.
Every project with controller must have independent system protection for
cases of too low or too high temperatures. The controller does not perform
protection functions for cases of too high or too low temperatures in the
system. High or low temperatures in the system can cause damage to the system
and user.
Introduction
Controllers ACD10 are modern designed, microprocessor-driven devices made with
digital and SMT technology.
The controller is provided as a constant temperature controller with actuator
designed for heating and cooling applications. The most common use is to
control the return temperature in the boiler and the stand-pipe temperature in
the system.

Installation of the controller
In a dry interior, the controller can be mounted directly on the mixing valve
with the help of the linkage kit provided. Avoid close proximity to sources of
strong electromagnetic field.
**** Each project with constant temperature controller ACD needs to base
exclusively on customer design and calculations and needs to be in compliance
with valid rules and regulations. Pictures, diagrams and text in this manual
are intended solely as an example and the manufacturer does not accept any
responsibility for them. If you use content of this manual as a base for your
project, then you carry also full responsibility for it. Responsibility of
publisher for unprofessional, wrong and false information and consecutive
damage are explicitly excluded. We retain the right for technical errors,
mistakes, changes and corrections without prior notice.
Installation of controlling devices should be done by an expert with suitable
qualifications or by an authorised organisation. Before you deal with the main
wiring, make sure that the main switch is switched off. You have to follow the
rules for low-voltage installations IEC 60364 and VDE 0100, law prescriptions
for prevention of accidents, law
prescriptions for environmental protection and other national regulations.
Hydraulic schemes
** Installation schemes show the principle of operation and do not include
all auxiliary and protection elements.
Scheme 1** – Control of return – heating
Scheme 1 – Control of return – cooling
Scheme 2 – Control of supply – heating
Scheme 2 – Control of supply – cooling
Commissioning of the controller
Controller is equipped with an innovative solution “Easy start” which enables the setup of controller in just few easy steps. When the controller is switched on for the first time and after the version of the program and the logo are displayed, the controller guides us to the initial setup with the animation on the display. Knob for manual operation must be removed to access the buttons. Initial setup is started by pressing the buttons and for 5 seconds.
Selecting heating or cooling operation
With the buttons and you can select the required operation mode – heating or
cooling. Confirm the selected operating mode with the button. If you
accidentally selected the wrong operating mode, you can return to the
operating mode selection with the button.
Selecting a hydraulic scheme
Here you select the hydraulic scheme for the controller operation. Use the
buttons and to navigate between schemes. Confirm the selected scheme with the
button. If you accidentally selected the wrong scheme, you can return to the
scheme selection with the button.
Select the opening direction of the mixing valve
Here you can select the opening direction of the mixing valve. Use the buttons
and to navigate between directions. Confirm the selected direction with the
button. If you accidentally selected the wrong direction, you can return to
the direction selection with the button.
Setting the lower limit for the requested heating temperature
With the buttons and you can determine the lower limit setting of the
requested temperature in heating mode. Confirm the setting with the button. If
you accidentally selected the wrong lower limit, you can return to the lower
limit selection with the button.
Setting the upper limit for the requested heating temperature
With the buttons and you can determine the upper limit setting of the
requested temperature in heating mode. Confirm the setting with the button. If
you accidentally selected the wrong uper limit, you can return to the upper
limit selection with the button.
Setting the requested heating temperature
With the buttons and you can determine the requested temperature in heating
mode. Confirm the setting with the button. If you accidentally selected the
wrong requested temperature, you can return to the requested temperature
selection with the button.
Setting the lower limit for the requested cooling temperature
**With the buttons and you can determine the requested temperature in
heating mode. Confirm the setting with the button. If you accidentally
selected the wrong requested temperature, you can return to the requested
temperature selection with the button.
Setting the upper limit for the requested cooling temperature
With the buttons and you can determine the requested temperature in heating
mode. Confirm the setting with the button. If you accidentally selected the
wrong requested temperature, you can return to the requested temperature
selection with the button.
Setting the requested cooling temperature**
With the buttons and you can determine the requested temperature in heating mode. Confirm the setting with the button. If you accidentally selected the wrong requested temperature, you can return to the requested temperature selection with the button.
