Regulating the Flow temperature in accordance with the outdoor temperature
The outdoor sensor can be connected either to the remote control or directly to circuit board SM 20015. The sensor
can thus be managed in one of two ways:
•
if the sensor is wired to the remote control, the climatic compensation curve is set by the remote itself (see
remote control installation and operating manual).
•
if the sensor is wired directly to the circuit board, the climatic compensation curve is set using the central
heating control knob. As the knob (fig. 2) is rotated, the numbers corresponding to the curve shown in figure 1
are displayed.
The factors governing the correction is reported in figure 1.
The selection of the compensation curve is determined by the maximum delivery temperature Tm and the minimum
outdoor temperature Te.
N.B.
The y-axis values of the delivery temperature Tm refer to standard 80-30 °C appliances or 40-25 °C floor-
mounted appliances. The type of appliance can be programmed using parameter 3 (see 5.1 “Parameter
programming”)
