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 power is
"On" or "Off" and has not operated for 24 hours for heating
or hot water, boiler pump will operate automatically for one
minute every 24 hours.
10.7 Low Water Pressure Sensor (Internal)
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).
