main circuit, which monitors the ﬂ ow and

protects the main heat exchanger from

thermal shock should there be a lack of

water in the system.

• Frost protection - contains an integral frost

protection system to prevent frost dam-

age which can occur in areas susceptible

to very cold weather conditions.

should the boiler not be used for longer

than 24 hours, it then performs a control-

led system test to ensuring the motorized

components within the boiler do not be-

come inoperable due to lack of use.

modulates based off central heating tem-

perature to within ± 2 ºF

• Diagnostic information system equipped

with three LED diagnostic lights for quick
