Feed With Drain
Used to lower the temperature of the drain water.
Frost Protectiion
When this is activated the unit will operate, at a preset demand level, if the temperature surrounding the unit falls
below a preset level, to prevent the pipework from freezing.
It is enabled by setting “frost demand” (via keypad/display) to >0 (it I disabled by setting “frost demand” to 0).
However the unit will not operate unless “frost demand” is set above the unit minimum demand level. Minimum
demand level for LE units is 21% and for LEP units it is 10%.
Frost demand is fully adjustable between 0 & 50%.
Timed Drain down.
Used to drain all the water from the cylinder if the unit remains on standby for longer than a preset (but adjustable)
time period.
For information on setting these options please see the display manual.
