1.1 GENERALITIES
DHW Controller (or “control unit”) is a control and management device for domestic hot water production used with
HP Heat Pump units.
The control unit can drive an heat pump and an electric resistor (until 4 kW) to manage the various function by
optimizing the electrical consumption.
The main functions are:
•
DHW production in storage tank
•
DHW recirculating management
•
Anti-legionella managemnt
•
SMART-ENERGY management
•
Anti-Freeze protection
