Heating Function
OPTIONAL SETTING: modulating temperature regulation with
compensated set point (technical parameter t01= 2)
(SATK2210 & SATK2220)
When the function is enabled, the flow temperature is modified
(±10°C with respect to the set point for HIU in HIGH
temperature, ±3°C if in LOW temperature) according to the
temperature detected by the return probe in order to maintain
this latter temperature value constant.
This keeps the actual thermal output of the slab under control,
and consequently also the ambient thermal load. The thermal
response time of the system is thus minimised.
This feature should not be used in combination with
thermostatic radiator valves.
When the function is enabled the display shows the symbol
OPTIONAL SETTING: weather compensation (technical
parameter t01 = 3)
When the function is enabled, the flow temperature is
calculated based on the temperature detected by the outside
probe (optional), in accordance with the curve shown below.
The “k” coefficient can be changed by pressing <SET> button
until the related setting appears.
The display shows the symbol .
(*)
if these set points cannot be changed you must set
parameter t07 to value 0 in the technical menu (see “access
to technical menu” below). Parameter t07 = 1 “freezes” the
operating set points to prevent inadvertent modifications by
the user.
