Domestic hot water technology

Controller FC3.10 for DHW modules

for FriwaMini up to 29 l/min (as per SPF LK 1*)

for FriwaMidi up to 50 l/min (as per SPF LK 1*)

for FriwaMidi-Kaskade up to 100 l/min (as per SPF LK 1*)

for FriwaMaxi up to 77 l/min (as per SPF LK 1*)

for FriwaMaxi-Kaskade up to 154 l/min (as per SPF LK 1*)

for FriwaMega up to 123 l/min (as per SPF LK 1*)

for FriwaMega-Kaskade up to 246 l/min (as per SPF LK 1*)

The controller FC3.10 sets the hot water temperature of the Friwa module via

the speed control of the primary pump. The control functions are adjusted

continuously during operation to the system conditions via an auto-adaptive

algorithm. A circulation control and operation of the return distribution valve

are additional functions of the controller. Different circulation modes are

possible which can be adapted to the system requirements.

An optional internet module for monitoring and parameterization of the

system can be acquired. The connection to the building control system is

realized by a modbus protocol.

* Indication of performance as per SPF test procedure,

LK 1 = performance indicator 1,

at a set domestic hot water temperature of 45 °C,

at a primary flow temperature of 60 °C
