6 Repeat the air purge, checking and replenishing process until:
▪ It is completely vented.
▪ There is sufficient water pressure.

Checking the minimum flow

The minimum flow must be checked with the heating circuit closed.
INFORMATION
If the minimum flow is too low, an error message may
appear and the heating system may shut down.
If the minimum flow rate is not sufficient, there may be air
in the circulation pump or the valve drive of the 3‑way
changeover valves (3UVB1/3UV DHW) is defective.
▪ Vent the circulation pump.
▪ Check the function of the valve drives; replace the
valve drive if necessary.
1 Close the valves and adjuster drives of all connected heat
distribution circuits.
2 Set operating mode "Heating" on the indoor unit controller
[→ Main menu → Operating mode].

Commissioning checklist

Commissioning checklist/Check off measures carried out
1. Supply indoor unit and outdoor unit (if present) with voltage
2. Enter "Expert code"
3. Set the operating parameters
[→ Configuration Wizard → Setting parameters]
[Hot water temperature target 1]
▪ Do not set below 40°C during commissioning.
▪ Never set below 35°C after commissioning!
4. Activate the ventilation function
▪ Check the water pressure
▪ Checking the minimum flow
5. Activate the "Heating" operating mode
Observe the waiting time (up to 5 min)
Observe "5.2 Commissioning at low ambient
ambient temperatures.
6.
Start-up is complete when the display shows the WW temperature
above 40°C.
7. [Screed drying] (if necessary)
Screed drying only after commissioning is complete. As soon as the
temperature of the storage tank is at least 40°C, activate (also possible without
outdoor unit).
Installation and operating manual

3 Read information parameters [Volume flow] [→ Main menu
→ Information → Values].
▪ The flow rate must be at least 480 l/h (see Controller operating
instructions).
INFORMATION
The controller of the indoor unit constantly monitors the
flow rate of the internal heat generator circuit. Different
minimum flow rate values are required depending on the
active operating mode:
"Heating" operating mode: 480 l/h
"Cooling" operating mode: 660 l/h
Automatic thawing function (Defrost) active: 780 l/h
If an error message regarding an inadequate minimum flow
is displayed at a flow rate of more than 480 l/h, check the
actual flow rate in the active operating mode and eliminate
possible fault causes.
5.5 Start screed drying (only if
required)
In the screed program, the flow 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+ HP1 controller
continues to work in the previously set operating mode.
