12 - OPERATION OF 61WG UNITS WITH SPECIFIC
HEATING CONTROL (OPTION 153)
12.1 - Operating principle
61WG units are specially designed to optimise the operation
of heating installations that require hot-water production for
a traditional heating system and domestic hot-water
production.
The Pro-Dialog+ control system of the 61WG units includes
algorithms that permit constant automatic optimisation of:
• control of a directional on/off three-way valve based on
the heating or domestic hot water requirements
• control of the electric heating stages allowing relief of
the heating loop
• hot-water setpoint reset (heating application) based on
the air temperature
• priority control between heating application and
domestic hot-water application.
NOTE: The installer is responsible for ensuring that the
installation complies with the applicable legislation in
terms of electrical and thermal safety.
