CAUTION
– t
he boiler must be installed in compliance with a design prepared in ad-
vance. Installation may only be carried out by persons trained by the manufacturer.
19. Choice and connection method of control and heating elements
Boilers are provided to the user with the basic boiler performance control elements compliant
with requirements for convenient heating and its safety. The regulation ensures that the required tem-
perature of the water exiting the boiler (80 - 90 °C) is adhered to. Boilers are fitted with an integral
thermostat for switching the pump in the boiler circuit on and off. Connection of these elements is
illustrated in the wiring diagram. Every pump in the system must always be controlled by an individ-
ual thermostat to avoid a temperature drop of water returning to the boiler 65 °C. When connecting
the boiler without an accumulation tank or equalizing tank, the pump placed in the heated building
circuit must be switched by an individual thermostat or electronic regulation so that it only operates
when the pump in boiler circuit operates. If two thermostats are used – each for switching one pump
– set the thermostat that switches the heated building circuit pump to 80 °C, and the thermostat that
switches the boiler circuit pump, to 75 °C. Both pumps may also be switched by just one thermostat at
the same time. If there is an adequately functioning gravity water circulation between the boiler and
the system, which prolongs the required temperature build-up, the value of the thermostat designated
for switching the boiler circuit pump can be reduced. Setting the required water temperature for the
building is always achieved by means of a three-way mixing valve. The mixing valve can be regulated
manually or by electronic regulation, which contributes to a more convenient and economical opera-
tion of the heating system. The connection of all the elements is designed by a specialist designer to
suit specific conditions of the heating system. Electric installations related to the additional equipping
the boilers with the above mentioned elements must be carried out by an expert in compliance with
valid ČSN EN standards.The electric connection of ACD01 unit you have to do after the wiring dia

Never switch off the ACD unit when off the season (by the main
switch on the boiler)!
