The NTC sensor for bottom water temperature measurement is with clip included to detect temperature by contact
and does not need conductivity thermal paste. In The HP270-3 and HP200/250-1 the same sensor becomes
discharge temperature control (T
dis
) as it is located between Electric heater and tank.
The NTC sensors for air and hot water are the same component, but give different information to the software in
the electronic control. Following table indicates the measurable resistance value to check and identify each proper
function, depending on the correspondent assembly position.
These NTC sensors (air and hot) are from 10kΩ type. In case their minimum and maximum operation values are
below or above the expected temperature/resistance values, the display will present the correspondent error code.
The NTC sensor in the fins is a 8kΩ type with characteristic listed on table 9.
