production
... with the following flow conditions:
The total flow rate of the two heating circuits is greater
than the maximum possible water flow rate of the
Vitodens 200-W B2HA boiler (see page 9 for maximum
water flow rate of boiler).
The use of a low-loss header is strongly recommended.
The low-loss header is available as accessory part.
The 3-way mixing valve, built-in to achieve the low-
temperature level of the under floor heating circuit, is
controlled by an accessory kit for a heating circuit with
a mixing valve.
