CONFIGURATION AND SYSTEM SETUP
BLOCK DIAGRAM
The heating system (radiators) is controlled by an On/O 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 conguration, the appliance 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  HEATMASTER 201 : HIGH TEMPERATURE
HEATING CIRCUIT WITH CONTROL BY ROOM THERMOSTAT AND
OPTIONAL OUTDOOR SENSOR.
