CONFIGURATION AND SYSTEM SET-UP
BLOCK DIAGRAM
The heating system (radiators) is controlled by an On/Off room thermostat.
The domestic hot water tank is controlled by an intermediate NTC sensor (optional). The domestic
hot water priority is always active.
In this configuration, the boiler constantly adapts its operation to the outdoor temperature, if an out-
door temperature sensor is connected.
The heating pump is triggered as soon as the room thermostat generates a heat demand.
BASIC CONFIGURATION - PRESTIGE 42 - 50 - 75 SOLO: HIGH
TEMPERATURE HEATING CIRCUIT WITH OPTIONAL DHW TANK AND
CONTROL BY ROOM THERMOSTAT AND OPTIONAL OUTDOOR SENSOR.
