For units assembled with Pump set up, the KVDEV kit can be installed for managing the domestic hot water production. The 3-way valve allows
deviating the water flow from the system to the technical water tank for the production of domestic hot water.
The kit includes two flexible pipes to connect the delivery and return of the unit.
The accessory must be mounted the closest possible to the heat pumps, in order to prevent a transfer of cold water inside the domestic hot
water storage, during the passage between heat pump chiller operation to produce domestic hot water.
The delivery and return fittings towards the system are available with 2" connections. The kit is equipped with RAL9018 painted bonnet.
Cable gland for wiring the power supply. IP 54 rate
