Pool
This is used to control pool heating production through an intermediate heat exchanger. Pool production can be enabled / disabled
with an external digital input.
Auxiliary equipment integrated in the heating buffer storage tank
This is used to control an auxiliary unit integrated in the heating buffer storage tank. It can be used for normal heat production or
as emergency equipment.
Auxiliary equipment integrated in the DHW storage tank
This is used to control a support system integrated in the DHW storage tank. This can be used as support to reach higher
temperatures during normal production, to carry out legionella protection programs or as emergency equipment.
Auxiliary boiler
This is used to control start-up / stop of an auxiliary boiler and regulate final temperature downstream from the boiler by a 0-10
Vdc modulating 3-way valve. The heat pump can use the boiler to assist in normal heat, DHW or pool production, or as emergency
equipment.

The hydraulic installation must ensure that while the boiler is operation, the temperature through the
heat pump never exceeds 65ºC, since this could cause serious damage to the refrigerant circuit.
NOTE
Simultaneous production
This is used to control systems that product heat and cold simultaneously. In these types of installations, the heat pump moves
energy from the cold production system to the various heat production systems and controls both the hot and cold outlet
temperature. On the other hand, it uses modulating valves to detour part of the cold or heat production to the brine system,
thereby maintaining the energy balance.
