14.5 CONNECTING THE OUTDOOR TEMPERATURE SENSOR

The SIEMENS model QAC34 outdoor temperature sensor (optional extra) for weather compensation must be connected to terminals 7-8 of terminal board M2 in figure 13.

The procedures for setting the gradient of the temperature curve “kt” vary depending on the accessories connected to the boiler.

a) Without QAA73 room temperature regulator:

The temperature curve “kt” must be selected by setting parameter H532 as described in section 16 “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

(2), button (2) on the boiler control panel, and modifying

the value displayed by pressing the

and

keys. See graph 3 for curve selection. (The example show

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.
