reflex ’servitec’
General description
Make-up ’servitec magcontrol’
With the ’servitec magcontrol’, the pressure in the heating or cooling system is registered and monitored with the help of the
pressure measuring transducer (2). If the filling pressure drops below p
F
= p
0
+ 0.1 bar, make-up deaeration is activated until
p
F
= p
0
+ 0.3 bar has been reached. The time (20 minutes default setting), cycles (3 in 2 hours) and quantity control (optional
- ’fillset’ with contact water meter) is active during this process.
Make-up ’servitec levelcontrol’
With the ’servitec levelcontrol’, make-up takes place
directly in the system dependent on the level in the vessel
of the pressure maintaining station. The make-up function
can be activated by way of a floating contact or an external
230 V~ signal. Time, cycle and optional quantity monitoring
is activated.
