Monobloc Outdoor Unit Installation Manual
10.4 Installation with remote user interface:
When the unit is equipped with a remote user interface, the control can be based on the air setpoint.
Depending on the occupancy and heating/cooling/DHW mode, the air setpoint is as given below. The air setpoint
can be configured in two ways:
• By direct access to the RC (refer to owner’s manual)
•
By access to the parameter menu via the RC or JBus / ModBus

Once air setpoints are defined, water setpoints must be configured for each occupancy.
10.5 Home Anti-freeze protection:
This protection is used on RUA-CP**01H, only when the remote user interface is connected. It is used to maintain
the minimum room temperature which is by default set to 6°C. When the room temperature goes below the Home
Anti-freeze setpoint [P427], the unit will run in Heating mode until the room temperature is increased: [P427] +
2°C.
Never switch off the unit, otherwise home anti-freeze protection cannot be guaranteed. For this reason the
main unit and / or customer circuit disconnect switch must always be left closed.
10.6 Water freeze protection:
When the OAT is low (and pump is stopped), the risk to freeze the water exchanger and the water pipes is high.
The pump shall be turned on regularly or continuously to make water circulate and decrease the risk. Likewise
the BPHE and piping electric heaters present on the hydronic kit (refer to Figures 7 and 8) are activated in some
cases.
The pump is controlled as follows:
•
If OAT goes below AntiFreezeDeltaSetpoint* [P517] + 6°C, the pump runs for 1 minute every 15 minutes at
maximum speed.
• If OAT goes below AntiFreezeDeltaSetpoint* [P517] + 6°C and EWT or LWT goes below
AntiFreezeDeltaSetpoint* [P517] + 4°C, the pump runs continuously at maximum speed.
• A 1K hysteresis is applied to exit these two overrides.
The electric heaters are controlled as follows:
• The electric heaters are energized during defrost and for 1 minute after defrost end.
•
The electric heaters are energized if OAT is below the AntiFreezeDeltaSetpoint* [P517] + 6.0 °C and if either
EWT or LWT are lower than AntiFreezeDeltaSetpoint* [P517] + 4.0 °C.
