. The central heating supply temperature is related to
the outdoor temperature sensor according to the algorithm
in Figure 53. To adapt the calculation line to the various
homes/ climatic conditions, all adjustment parameters must
be set according to the following sections. The calculated
supply temperature is visible in parameter
1012
.
Corrections can be made to the line via parameter

as shown in Figure 53.
7.10.1 - Outdoor reset: which systems?
“Outdoor reset” is a more sophisticated and precise
adjustment than the “Constant setpoint adjustment”.This
feature is able to make full use of appliance efficiency and
is suitable for the following types of system:
- Small systems, with radiators and where there is one
room whose temperature is characteristic of all other
rooms. The room thermostat makes the appropriate
corrections to the room temperature by switching the
appliance pump on and off.
- Large systems, with radiators, where each area is
controlled by its own room thermostat and the appliance
pump is stopped only when all area thermostats are
satisfied (appropriate electrical system set-up required).
- Small systems, with radiant panels (low temperature),
where there is one room whose temperature is
characteristic of all other rooms. The room thermostat
makes the appropriate corrections to the room temperature
by switching the appliance pump on and off.
- Large systems, with radiant panels (low temperature),
where each area is controlled by its own room thermostat
and the appliance pump is stopped only when all area
thermostats are satisfied (appropriate electrical system set-
up required).
