Pipe connections HBS 16
Install as follows:
႑
First drain the boiler water reservoir/heating system if
filled with water.
႑ Position the extra heat medium pump (EP21-GP20) in a
suitable location outside HBS 16.
႑
The shunt valve (EP21-QN25) is located on the flow line
after HBS 16, before the first radiator in the heating
system 1. The return line from heating system 2 is con-
nected to the shunt valve (EP21-QN25) and to the return
line from heating system 1, see illustration on page 11.
႑
The flow sensor (EP21-BT2) is installed on the pipe after
the heat medium pump (EP21-GP20).
႑
The return line sensor (EP21-BT3) is installed on the pipe
from heating system 2.
႑ When installing the sensor, heat conducting paste must
be used and the pipe must be insulated to obtain the
correct temperature measurement.
NOTE
Incorrect installation can affect the function.

Choose between seven settings on the pump. You can
choose between three different constant speeds (I, II or
III) or two different curves, one proportional pressure (PP)
and one constant pressure (CP), where 1 is lowest and 2
highest.
