10.5 Frost Protection
Boiler monitors supply and return water temperatures to
enable frost protection which automatically turns boiler
and pump on.
If water in boiler falls below 41°F (5°C), providing boiler
is connected to power, boiler will operate until water
temperature in the system reaches approximately 86°F
(30°C).
Frost protection is for boiler only and not for complete
Central Heating System.
10.6 Pump
If electricity is connected to the boiler, regardless if
hours for heating or hot water, boiler pump will operate
automatically for one minute every 24 hours.
10.7 Low Water Pressure Sensor (Internal)
This device protects primary exchanger from damage.
It will not allow boiler to run in a LOW water pressure
situation. Low water condition occurs when water
pressure drops below 7.0 psi (0.5 bar).
