ANTI-LOCK CIRCULATOR
If the circulator, has not performed any operation cycle in a period of time of 24 hours, it is
activated for 10 seconds, in order to avoid long idle block. At the end of the post-circulation
phase, activated following a request for domestic hot water, the electric diverter valve is powered
for 2 seconds to avoid blocking for long periods of inactivity.
