14.13 - Water and
fl ue temperature
sensor
The boiler has a number of sensors
that measure temperature. The
electrical resistance between the
sensor wires must correspond with
the values shown in Figure 14-8.
The temperature sensors are: U1; U2,
U3, U5, U6, U7 and U8. The location
of each sensor can be found in Figure
3-1 and Section 14.15 and 14.16.
14.14 - Outdoor
temperature sensor
(optional)
An outdoor temperature sensor
can be connected to the boiler
(see section 8.1.4). The electrical
resistance existing between the
sensor wires must correspond with
the values shown in Figure 14-9.
