ROTEX HPSU low temperature Bi‑bloc
4P384979-1B – 2016.02
Setting Value
External room thermostat for the
main zone:
▪ #: [A.2.2.4]
▪ Code: [C-05]
1 (Thermo ON/OFF): When the
used external room thermostat or
heatpump convector can only
send a thermo ON/OFF
condition.
Benefits
▪ Wireless. The ROTEX external room thermostat is available in a
wireless version.
▪ Efficiency. Although the external room thermostat only sends ON/
OFF signals, it is specifically designed for the heatpump system.
▪ Comfort. In case of under floor heating, the wireless external
room thermostat prevents condensation on the floor during cooling
operation by measuring the room humidity.

▪ The underfloor heating or radiators are directly connected to the
indoor unit.
▪ The desired room temperature is set via the remote controller of
the heatpump convectors.
▪ The space heating/cooling demand signal is sent to one digital
input on the indoor unit (X2M/1 and X2M/4).
▪ The space operation mode is sent to the heatpump convectors by
one digital output on the indoor unit (X2M/32 and X2M/33).
INFORMATION
When using multiple heat pump convectors, make sure
each one receives the infrared signal from the remote
controller of the heatpump convectors.

Unit temperature control:
▪ #: [A.2.1.7]
▪ Code: [C-07]

is decided by the external
thermostat.

External room thermostat for the
main zone:
▪ #: [A.2.2.4]
▪ Code: [C-05]
1 (Thermo ON/OFF): When the
used external room thermostat or
heatpump convector can only
send a thermo ON/OFF
condition. No separation between
heating or cooling demand.
Benefits
▪ Cooling. The heat pump convector offers, besides heating
capacity, also excellent cooling capacity.
▪ Efficiency. Optimal energy efficiency because of the interlink
function.
▪ Stylish.
Combination: Underfloor heating + Heatpump
convectors
▪ Space heating is provided by:
▪ The underfloor heating
▪ The heatpump convectors
▪ Space cooling is provided by the heatpump convectors only. The
underfloor heating is shut off by the shut-off valve.

a Remote controller of the heatpump convectors
▪ The heat pump convectors are directly connected to the indoor
unit.
▪ A shut-off valve (field supply) is installed before the under floor
heating to prevent condensation on the floor during cooling
operation.
▪ The desired room temperature is set via the remote controller of
the heatpump convectors.
▪ The space heating/cooling demand signal is sent to one digital
input on the indoor unit (X2M/1 and X2M/4)
▪ The space operation mode is sent by one digital output (X2M/32
and X2M/33) on the indoor unit to:
▪ The heatpump convectors
▪ The shut-off valve
