Programmers
Statesman 45/50, 50/70, 70/90, 90/110
The operation is shown in the instructions supplied
with the programmer kit.
Important: Where this programmer is fitted to existing
gravity systems without independent temperature
control of the domestic hot water (i.e. cylinder
thermostat/zone valve), it will not be possible to use
all the available programme options (i.e. central heating
cannot be operated separately from hot water).

This model cannot be fitted with the optional Potterton
integral programmer. If fitting an external programmer,
the instructions on how to operate it should have been
supplied by the manufacturer.

For the winter period, drain entire system including

Frost Protection
If frost is likely during a short absence from home,
leave the heating controls on a time reduced setting.
Alternatively a frost stat may be fitted.
Consult your installer on whether any other thermostat
is required.
For longer periods, the entire system should be
drained, including the domestic water supply.
Frost Precaution
A boiler which is shut down for several hours in very
cold weather may be in danger of freezing due to its
position (i.e. it may be in the outhouse, etc.) or part of
the pipework of the system may be vulnerable to frost.
To avoid freezing, protection should be provided by
adequate insulation, taking care not to impede the fresh
air supply to the boiler.
Cleaning the Outside of the Casings
The outside of the boiler casing can be wiped when
necessary by using a damp clean cloth to remove
finger marks etc. Do not use abrasive cleaners as this
may damage the casing finish.
