If system tends to overheat above thermostat's
temperature setting, reduce heat anticipator setting by

possibility, the heating system should not be
left unattended in cold weather; or appropriate
safeguards and alarms should be installed on the
heating system to prevent damage if the boiler is
inoperative.
