12.6 CONNECTING THE OUTDOOR TEMPERATURE SENSOR PROBE
The procedures for setting the gradient of the temperature curve "kt" vary depending on the accessories con-
nected to the boiler.
a) Without QAA73 room temperature regulator:
The temperature curve "kt" must be selected by setting parameter H532 as described in section 14 "setting the
boiler parameters".
See graph 2 for selecting the curve referred to a room temperature of 20°C.
The chosen curve can be shifted by pressing the
the value displayed by pressing the
in graph 3 refers to the curve Kt=15).
Increase the value displayed if the room temperature required is not reached inside the premises for central heating.

b) With QAA73 room temperature regulator:
The temperature curve "kt" must be selected by setting parameter 70 "HC1 curve" of the QAA73 room tem-
perature control device as described in section 12.4 "QAA73: parameters which can be set by the installation
(service) engineer".
See graph 4 for selecting the curve referred to a room temperature of 20°C.
The curve is shifted automatically on the basis of the room temperature set using the QAA73 climate control.
QAA73 must be selected by setting parameter H532 as described in section 14 "setting the boiler parameters".
