MANAGING
Functions:
− Reads system sensor (SS)
− Controls thermal unit two-way valve (V1)
− Controls system pump (PS)
− Controls DHW pump (PB) instead of the LPG gas solenoid
valve (VLPG)
− Reads storage tank sensor (SB)
− Manages control of mixed zone 3 zone management (ZM)
device via bus. Up to a maximum of 16 devices can be
managed.
