1.13 Frost Protection (Ice Protection function)
Ice Protection function works to reduce the risk of freezing and thereby protect the fabric of the
boiler if either the CH Flow or CH Return temperature falls below 5°C. The ice protection
function will force the appliance to operate until the CH Flow temperature rises above 30°C.
This mode operates even when all timeclocks are set to ‘OFF’, and also if the control panel is
set to the ‘OFF’ mode using the Mode button (3).
Be aware of unexpected firing in these conditions.
The boiler must have a permanent live AC supply and an adequate fuel supply for the function
to operate.
When the function is operating ‘ICEP’ is displayed on the LCD.
1.14 Circulating Pump and Diverter Valve Exercise Functions
If the boiler has not operated the circulating pump or the diverting valve for a period of 24 hours,
it will operate these components for 10 seconds to prevent locking.
The boiler must have a permanent live AC supply for this function to operate.
1.15 Speed adjustment of the circulating pump
1.15.1 Combination Boilers
The speed of the circulating pump is controlled in both CH and DH modes by a signal from the
control panel. If the maximum speeds need to be adjusted to suit site conditions, refer to
Engineer Parameters in Section 11.7.1. The settings on the circulating pump must not be
adjusted from the factory default of PWM Profile A (heating).
1.15.2 Pumped and System Boilers
The speed of the circulating pump can be adjusted using the pushbutton and LED indications
on the pump. Please refer to the manufacturer’s documentation which is available via
www.warmflow.co.uk/support/downloads.
