Page 18: Control Specification
2.5 Control specification All Evinox satellites are equipped with a regulation system for heating and DHW temperature control. The regulation strategy foresees different applications: radiators, fancoils, underfloor heating and can be configured accordingly. 2.5.1 Heating When the room temperature Ta drops below the set point Ts: ... -
Page 19: Pressure Loss And Head
2.6 Pressure loss and head The following diagrams show the primary circuit pressure loss according to the ModuSat equipping and the head feature head available to the apartment circuit. The head available for the apartment circuit is given by the difference between the pump head and the ModuSat pressure loss. -
Page 20: Dhw Capacity
2.7 DHW capacity The quantity of DHW depends on the storage capacity, the supply temperature, the primary temperature and the cold water temperature. The following table shows the max DHW quantity according to the tank capacity and the primary circuit temperature with: ... - Page 21 For a satisfactory domestic comfort, it is generally allowed to adopt a value of 15 l/min for a bathroom comprising a 150-litre bath and 9 l/min shower. It should be noted that the reduction in the primary flow will influence the time of the warm up of the stored water regeneration, but that at the moment of the first draw off, the ModuSat contains the total capacity at the temperature of the primary circuit (the specific flow takes into account two successive hot water draw of)

Page 24: Sizing Of The Primary Circuit
In order to guarantee the hydraulic independence of the boilers and of the installation, a mixing header is installed between the boilers and the primary distribution system. Use either Evinox headers or Evinox packaged boilers with built in headers. 2.10.1 Design of the boiler room The ModuSat’s provide each apartment with heating and the production of hot water and... - Page 25 The examples below correspond to the sizing of ‘standard’ housing units. For installations known as ‘luxury’ or for specific hot water requirements, please contact the technical department at Evinox. The calculated power is the power required at the boiler room outlet. The basic hypotheses for these calculations tend to the best sizing of the boiler room plant in order to obtain the best efficiency of annual generation.
- Page 26 2.10.4 Small installations up to 10 units Taking into account the relatively short peak period, storage, and speed of regeneration, the coincidence factor typically used for sizing a hot water production unit located in the boiler room can be weighted. Indeed, even if the boiler room only has to satisfy mainly the production of hot water, this will only be for a short period, during which the inertia of the building will limit any lowering of the room temperature.
- Page 27 2.10.6 Refurbishment projects When the ModuSat is installed within a refurbishment project and the central boiler room is preserved, the power of this boiler room will in the majority of the cases be reduced. The fact of individualising the production of domestic hot water (300 or 400 litres available in each apartment) can imply a lower power boiler plant size for the provision of hot water.
- Page 28 primary circulation of the horizontal distributions to the hours of use of hot water and thermal maintenance of the hot-water tanks (i.e. a few hours per day). The boiler room can profit from the systems of regulation and programming. Nevertheless, the temperature of the primary circuit will not be lowered under 60°C, in order to ensure a production of satisfactory domestic hot water on demand.

Page 29: Installation
3 INSTALLATION MODUSAT is delivered in a proper packaging, after removing it check the integrity of the unit as well as the presence of all parts. In case of damage or missing parts contact the supplier. Packaging materials must not be left at children’s reach because potentially harmful. -
Page 30: Modusat Positioning
For the unpacking of the appliance from the carton, it is recommended at least two people perform any lift. It is recommended to cut the base end of carton and open the carton flaps. Ensure the protective packing over the ModuSat tappings on the top of unit is kept in place, then remove carton by sliding up over the unit. -
Page 31: Checks Before Connecting The Modusat
Next rinse the entire circuit to make sure all products used to wash it are removed. During this process, it is forbidden to use any chemical or other products not approved by EVINOX. The non observance of this rule invalidated the warranty. Remove the electric power supply before any installation operation. -
