The TEC 100/200 has three temperature sensor inputs, these being
Flow,
Return/Hot Water
and
External
. Connections are as shown in Fig.5.

Flow / Return Temperature Sensors (Cable Type)
Using
heat resistant
cloth tape,
tightly
strap the sensors to the relevant
flow
and
return
pipes,
close
to boiler,
before
any branching connections.
Cover the sensors with heating pipe insulation and strap with ty-wraps or
similar. See Fig.6.
