Viessmann VITOSOLIC 200 Installation And Service Instructions Manual page 142

Function description
Heat statement
Statement without flow meter
■ Statement:
As an estimate through the differential
between the flow and return tempera-
ture and the set throughput (see the
collector service instructions).
■ Sensor inputs S1 and S10 to S12 are
provided in the delivered condition for
this purpose.
Should the flow temperature sensor
have to be located at a point where
temperatures in excess of 95 °C could
occur, always connect it at S1 or S9
(NTC sensor with 20 kΩ) (see also
page 69).
Note
Sensors that are already installed may
be used.
These must be switched over (see
page 161).
■ The statement will be calculated if the
output set in "Relay" (see the following
section) is activated.
Example
Use the pump on R1 and the sensors S1
and S2 for the statement.
Make the following settings at the
solar control unit:
1. Main menu
■ "HM"
■ "Options"
– "HM 1" or "HM 2"
Set "Yes".

■ "HM 1" or "HM 2"
■ "Contractor"
– "Sen. Flow"
Set value "1" for sensor S1.
– "Sen. Return"
Set value "2" for sensor S2.
– "Frostprot.type"
Set the value for the heat transfer
medium selected.
– "Frost protection"
Select the mixing ratio of the heat
transfer medium.
– "Flow transm"
Select "No".
– "Throughput"
Set a value in l/min.
"Relay"
Set value "1".
Note
To scan the throughput volume in
menu "Manual mode" for the
responding actuator (in the example
for relay 1) select "On". Scan the
value at the throughput display of the
Solar-Divicon.
