"Heating" mode 10l/min
"Cooling" mode 15l/min
"Defrost" mode 25l/min
Tab.5-1 Required minimum flow rate
1 Use the heating circuit configuration to determine which heating
circuits can be closed by mechanical, electronic or other valves.
2 Close all closable heating circuits (see step1).
3 Select the "Heating" operating mode [→Main menu →Operat-
ing mode].
4 Check the [Volume flow] information parameter [→Main menu
→Information →Values]. The displayed value must be equal to
or greater than the value for "Heating" mode in Tab. 5-1.
5 If the flow rate is too low:
▪ Bleed the hydraulics and heating circuits.
▪ Check the function of the valve drives; replace the valve drive if
necessary.
5.5 Start screed drying (only if
required)
In the screed program, the inflow temperature is controlled according
to a pre-set temperature profile.
See the controller operating instructions for further information on
the screed program, its activation and sequence.
After the screed program has ended, the RoCon+ HP controller con-
tinues to work in the previously set operating mode.
