tank sensor instructions.
FROST PROTECTION
5.6
The appliance is fitted with a frost protection device. In the event of very
cold conditions, the pump may operate and the appliance light for a few
minutes to protect the appliance and system from potential frost
damage. This can only function if the gas and electricity supplies are
maintained and the ON/OFF switch on the appliance is left ON. (‘l’) On
CBX appliances the time clock can be switched to the OFF setting.
OVERHEAT PROTECTION
5.7
The appliance incorporates flow and return thermostats, which monitor
the appliance's operating temperature. Abnormal temperatures such
as overheating will cause the appliance to go to lockout and the
Reset
button will show steady RED, if the error codes are accessed the LED 4
(code 0001) will illuminate. Allow the appliance to cool, and then press
the
Reset
button to clear.
