CIRCULATION PUMP CHECKS
The circulation pump can run in different modes depending on the requirements of the system to which the unit is connected:
parameter Pqd sets every how many hours the start-up is set for and parameter Pqt sets how long the pump is to run
during the anti-locking cycle.
DOMESTIC WATER PRODUCTION
The appliance can be connected to a tank with an intermediate exchanger to produce domestic water. The 3W internal units
The domestic water request can occur in two ways:
below 60°C.

Via parameter hyS it is also possible to check the hysteresis cycle of the tank temperature check.

towards the DHW tank. When the required temperature is reached, the compressor stops, the refrigerant cycle inversion
valve and the 3-way valve are switched and the compressor starts three minutes after the previous stoppage.
During domestic water production the system dispenses the maximum power possible to rapidly meet the domestic water
request.
ANTI-LEGIONELLA CYCLE
Through the activation of the anti-legionella function, the adjuster is able to conduct the thermal disinfection procedures
autonomously on domestic hot water systems, considerably reducing the risk of the presence and proliferation of the bacteria
responsible for legionella.
The disinfection function is activated in parameter Ldi. The user can opt to heat the domestic water with the heat pump and
The time interval for running the cycle in days, for how long and at what temperature to run the disinfection cycles are set
respectively in parameters LdS, Ldd and Ldt.
