7. Operational check
Carry out a operational check when the energy meter has been fully mounted. Open
the thermo-regulators and cocks in order to establish a water flow through the
heating system. Activate the upper push button on the MULTICAL® 601 and check
that the display values for temperature and water flow are reliable.
8. Electrical connection for MULTICAL® and
ULTRAFLOW®
The polarity of the temperature sensors T1, T2 and T3 is
unimportant. Use below colours at the flow sensors V1 and V2
when connecting the ULTRAFLOW® and electronic pick-up units.
Flow sensors with Reed switch output must be connected to
terminals 11-10 and 11-69, respectively.
