OPERATION WITH OUTDOOR NTC PROBE
The system is prearranged for the connection to an NTC sensor, which measures the external
temperature outside the building in which the installation is placed. The available adjustments in
this heating mode are the calculated center CH Set Temperature and the heat dispersion
coefficient of the room walls. To connect the outdoor NTC probe, firstly PP15 Outdoor sensor type
parameter’s value must be changed to Outdoor sensor available (1). Outdoor temperature
measurement starts only if PP15 is selected as 1. If PP15 is selected as 1 and outdoor NTC probe is
not connected F6 error code is shown on the display but boiler keeps working.
Note: The set-point calculated by the external probe formula is never higher than the maximum
temperature range and never lower than the minimum temperature range of the wall / floor
central heating. CH Set Temperature is calculated according to the below graphics.
