Fitting and Wiring Temperature Sensors
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.
