NIBE PVT 40 makes it possible for your heat pump to use NIBE PVT panels as a heat source. The heat pump regulates the temperature of incoming brine in the summer, and closes the shunt valve in the winter when the temperature reaches the set value.
ECS 40 is used when heat pump is installed in houses with up to four different climate systems that require different flow line temperatures, for example, in cases where the house has both a radiator system and an under floor heating system.
NIBE OPT 10 is used to enable connection and control of gas boiler NIBE GBM 10-15
Extra heating circuit (recommended 80-250 m2 floor heating). ECS 41 is used when heat pump is installed in houses with up to four different climate systems that require different flow line temperatures, for example, in cases where the house has both a radiator system and an under floor heating system.
HTS 40 is an accessory that records humidity and temperature.
A NIBE heat pump can be controlled and monitored by external Modbus equipped equipment.
NIBE SOLAR 42 enables solar heating with your heat pump. With additional solar panels and VPBS you get a complete system.
Passive cooling. PCS 44 is used when heat pump is installed in an installation with passive cooling.
Communication and control. EME 20 is used to enable communication and control between the inverter for solarcells and heat pump/indoor module/control module.
Makes hot water priority possible at large heat pump outputs. (charging power between 15 and 40 kW), together with an SMO 10 and F1330-40. This also requires a hot water accumulator, for example, NIBE VPA.
Accessory card. An accessory card is required if step controlled additional heat (e.g. external electric boiler) or if shunt controlled additional heat (e.g. wood/oil/gas/pellet boiler), passive/active cooling 2 pipe, passive cooling 2 respectively 4 pipe or if hot water comfort is to be connected to F1345. An accessory card is also required if the ground water pump or external circulation pump is connected to F1345 at the same time that the buzzer alarm is activated.
