Version Equipped with larger heat exchanger and if required matched cooling water pump
Function Higher heating water return temperatures 90 / 75 °C, e.g. for operation with an absorption cooling
system
• Please note: Heating output reduced by 5 % with the same energy usage
• Please note: After inspection, there may be additional maintenance costs due to the thermal load
of the engine oil
Delivery Fitted in the CHP module
5.2 Heating water temperature control
Version See Viessmann catalogue
Function See Viessmann catalogue
The Vitobloc 200 contains a controller with a continuous output signal 0..10 V as standard. Via an on-
site mixing valve with servomotor, it regulates either the heating water return temperature or an on-site
variable speed heating water pump for a constant ow temperature.
Note Biogas modules should always be tted with a heating water return temperature raising facility!
