must be set at a temperature
pump
which prevents the contents
of the thermal store exceeding
100°C. See page 26 for further
guidance. Installer must set the
thermostat correctly during
commissioning.
NOTE
As part of system setup and commissioning, it is important that this boiler hold-off pipe thermostat
be adjusted to find the best setting for each individual installation.
Failure to do so will give under performance of either the boiler or the solar heating system

NOTE
Some solar controllers, the overheat protection is provided by a temperature sensor,S3,
which is wired directly to the solar controller same as sensors S1 and S2
In this case the mechanical overheat thermostat (S3) shown in this diagram is not required and
the solar pump is wired straight to the solar controller.
