CONNECT AT/BT
In case of using CONNECT AT/BT, accessory supplied on request,
the boiler gives the possibility to choose 2 thermoregulation curves:
- OTC 1 CH (parameter 45) for a direct system
- OTC 2 CH (parameter 47) for a mixed system.
Even in case of second circuit (2CH) the curve depends on the
external minimum project temperature (on the geographical area,
therefore) and on the delivey project temperature (on the type of
system, therefore); the installer must to put attention to calculate it
using the following formula:
rated delivery T - 20
P. 47 = 10 x
20- rated min. external T
Parameters 31 and 32 give the possibility to define the maximum
and the minimum central heating set-point of the second circuit.
To correct the curve in this configuration, please refer to the
instructions supplied with the accessory.
