When there is a second temperature application, a secondary pump is the circulating pump for
the secondary heating circuit.
Terminals intended for the connection of the Aquastat security accessory (ATW-AQT-01) for
controlling water temperature of the circuit 2.
If DHW tank contains an electric heater, the air to water heat pump can activate it if the heat
pump cannot achieve the required DHW temperature by itself.
Common terminal for the 3-way valve for DHW tank.
The air to water heat pump can be used to heat DHW. This output will be on when DHW is
activated.
Neutral terminal common for 3-way valve of DHW tank and outputs 1 and 2.
The air to water heat pump can be use to heat swimming pool. This output will be ON when
swimming pool is activated.
When there is a hydraulic separator or buffer tank, additional water pump (WP3) is needed.
The boiler can be used to alternate with the heat pump when the heat pump cannot achieve the
required temperature by itself.
A water electric heater (as accessory) can be used to provide the additional heating required on
the coldest days of the year.
Output for solar combination with Domestic Hot Water Tank.
