5.3 Heating water connection set
Version See Viessmann catalogue
Note To complete the heating water connection set, the installation of a heating water pump is additionally
required. It should be sized on site to the required delivery head (and possibly delivery ow rate). (For a
recommendation for heating water pump sizing, see 0). If using a variable speed pump, an input signal of
0-10V is required if the return temperature raising facility is not used.
The shut-off valves for Vitobloc 200 EM-238/363, EM-363/498, EM-401/589 and BM-366/437 should be
ordered separately:
EM-238/363 2 shut-off valves DN 65
EM-363/498, EM-401/589, BM-366/437 2 shut-off valves DN 80
