UNIT CONFIGURATIONS
SRH units are available in 2 configurations:
SRH:
The unit is designed to have both refrigerant circuits condensed by air; in this configuration the unit will always
transfer the thermal load (electric input power + condensation load) to the air having so, the temperature
increase reported in the performance data (see previous pages).
SRH/WZ:
The unit is designed to have one refrigerant circuit condensed by air, the other one condensed either by water
and air. If the unit is supplied with the advanced control panel it is possible to set the operation priorities:
Priority air temperature : When the priority is the air temperature the unit operates in order to keep the air
temperature below the required set point; in case the air temperature tends to increase, it is activated the partial
heat recovery who transfers to the water part of the thermal load of the unit. When the partial heat recovery is
activated the supply air is at the same temperature of the return air.
Priority water temperature When the priority is the water temperature the unit operates in order to keep the
water temperature below the required set point; in case the water temperature tends to increase, it is activated
the air condenser who transfers to the air part of the thermal load of the unit. When the partial heat recovery is
activated the air discharge temperature is neutral.
Both SRH versions can be supplied either with basic control panel or advanced control panel.
Nevertheless, the priority operation modes described above are available using the advanced control
panel only.
SRH/WZ units supplied with basic control panel, are only available in “air temperature priority” .
