Viessmann VITOCAL 160-A - Condensate drain; Connection to a solar circuit (type WWKS)

6.4 Condensate drain
When heating domestic hot water using the ambient air, and in venti-
lating mode, condensate forms on the inside of the heat pump module.
This needs to be routed via the condensate drain to a sewer.
Note
Because of the risk of backpressure, connecting the condensate drain
to foul water pipes is not permissible.
Condensate drainage via siphon

Condensate drainage via water seal

6.5 Connection to a solar circuit (type WWKS)
By incorporating a solar thermal system the already low costs for DHW
heating can be even further reduced.
With this in mind the Vitocal 160-A features an integral temperature
differential control unit, and the collector temperature sensor is part of
the standard delivery.
The solar flow and return are connected at the connection fittings
(R ¾") on the solar heat exchanger integrated in the Vitocal 160-A.
