Climatic Curve Setting - Alpha Smartech Plus Instructions Manual

10 CLIMATIC CURVE SETTING

Select the 'CURVE' screen to enable/disable (disabled by default) climatic offsetting with external temperature and to set up
the relevant operation parameters. See Fig. 10.1.
The offset curve establishes how the system flow temperature TM is corrected according to the external temperature TE.
Note: The external temperature value TE is detected by the external units probe.

RECOMMENDED CURVE SETTING
VALUES
Under floor heating systems:
TMmin = 25°C
TMmax = 40°C
Fan coil heat emitters:
TMmin = 35°C
TMmax = 50°C
Radiator system (existing radiators):
TMmin = 40°C
TMmax = 60°C
Replacement radiator systems
(correctley designed):
TMmin = 35°C
TMmax = 55°C
The outside temperature settings:
TEmin = 0°C
TEmax = 20°C
