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 14.4 “QAA73: parameters which can be set by the installation engineer (service)”.

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 con- trol.

If the system is divided into zones, the temperature curve “kt” relating to the part of the system not control- led by the QAA73 must be selected by setting parameter H532 as described in section 16 “setting the boiler parameters”.

IMPORTANT: For systems divided into zones, parameter 80 “HC2 curve”, which can be set on the QAA73 room temperature regulator, must be set as _ _ . _ “not active” (see section 14.4).
