Based on this issue, the system has no frost protection off mode. It is ilogic to get frost protection at 0° C. At that temperature, the water is already frozen.
Zero temperature logic was to give user option to disable frost protection but looks like deadband and weather factor makes value -

some times i run into same issue but for me workaround to this is to check last temperature reporting time.
i think fix is easy, change line 551 in boiler.php
from
if ($zone_c < $frost_c-$zone_sp_deadband){
to
if (($zone_c < $frost_c-$zone_sp_deadband) AND ($frost_c!=0)) {
i think this should work. the en.php already have information about 0 setting,
this one is moved to maxair as well, i suggest to commit one line change to old version. (1.77) https://github.com/pihome-shc/PiHomeHVAC/issues/44
i have very strange from this system, i was under the impression if i put frost protection to 0 then system will never go to frost protection mode boiler.php output
no status for frost protection icon
