Outlet units
These can manage as many as four different outlet temperatures. This is done by managing one direct outlet unit and three
combined outlet units. The combined outlet units have to use modulating 3-way valves with an analogue signal of 0-10Vdc. Each
outlet unit has independent terminals for heating and cooling demands. These signals are supplied with 24Vac or 24Vdc voltage.
DHW Recirculation
This is used to control activation of the DHW recirculation pump, depending on the temperature recorded in the recirculation line
and the established time schedule.
