MULTICAL® 403
7 Testing of function
Carry out an operational check when the energy meter has been fully mounted. Open
thermoregulators and valves to enable water flow through the heating system. Activate the front
key of MULTICAL® to change display reading, and check that the displayed values for temperatures
and water flow are credible values.
8 Electrical connection
The two matched two-wire sensors are
mounted in terminals 5 and 6 (t1) as well
as 7 and 8 (t2). The polarity of temperature
sensors t1 and t2 is without importance for the
functionality.
Please also see the position of the terminals in
