Introduction

The hydronic module is used to control heating or cooling
zones, each of which can be fan coil, underfl oor circuit or
radiator.
Additionally the module can be used to heat up water in an
external sanitary water tank and for swimming pool heating.
The module is connected to an air source outdoor unit ( here
after referred to as CDU ).
The hydronic module controls the CDU in heating or cooling
in order to achieve the desired water temperature in the
heating / cooling zones and the desired temperature of the
sanitary hot water.

16 Safety recommendations ...................................................
The water temperature for the heating / cooling zones is
determined by the hydronic module control ; the sanitary
water temperature is determined by the sanitary water tank
control.
The hydronic module is equipped with a pump to circulate
the water in the primary circuit and (with the exception of
80AW100- and 80AW200-) with electrical heaters.
