ENERGY RATING
Multiparva 3.0 is a latest generation extremely high efficiency condensing boiler for heating only, equipped with a pre-mixed modulating burner with low emissions and stainless steel condensing heat exchanger with high calorific power values. It is available from 35, 45, 70, 95, 110, 115, 150 heat capacity . It can be installed individually or up to 6 modules can be combined, of the same or mixed heat outputs, directly exploiting the boiler electronic control unit. Multiparva Cond 3.0 exploits the condensing principle: thanks to the innovative heat exchanger in stainless steel and the two separate sections, one dedicated to condensing only, it is able to recover the latent heat contained in the flue gases, obtaining efficiency levels which are some of the highest in the category. Multiparva Cond H can be installed inside a boiler room or, thanks to the Roof Top version, it can be enclosed inside a cabinet on the outside of the building or on the roof itself. This solution is extremely advantageous in the case of thermal requalification of a boiler plant.
The Multiparva 3.0 condensing boiler can be installed individually in heating only (SR) or heating installations with provision for combination with a remote boiler (SV), thanks to the combination of the appropriate kits.
It can be installed inside a boiler room or, thanks to the specific Roof Top version enclosed inside a cabinet, outside the building or on the roof of the same, an extremely advantageous solution in case of redevelopment of a thermal power plant. The module is pre-assembled and contains the boiler and its kit (SR or SV) inside.

MMI remote control
Simple MMI is a remote user interface (or ambient unit) equip- ped with an OpenThem® communication protocol which is designed to control the boiler (remote control) and the zones in which it is installed (chronothermostat with weekly set- tings). Thanks to two-way communication with the boiler, the Simple MMI module lets the user check/set the temperature of the heating water and the DHW without having to go to the boiler plant.
Functional features
The Simple MMI is a remote control for boilers with a weekly time program.
The main features are:
- Weekly programming clock
- Automatic or manual operating mode
- Activation/deactivation of DHW and heating (radiators)
- Display of ambient temperature and time
- “Smart Shower” function which allows the temperature of the DHW to Display of be set at the required level for a set time
- Display of boiler settings
- Two-way communication with the boiler via the OpenTherm® protocol
Display of system information
Each time the knob K4 is pressed, the following system information is displayed in a cycle:
- Temperature outside the building (simple display, only if connected to the relative sensor)
- Temperature set for the water in the heating system (turn the knob K4 to modify the set value)
- Temperature set for the hot water in the DHW system (turn the knob K4 to modify the set value). This is the default temperature when the “Smart Shower” function is not active
- Actual temperature of the water in the heating system (simple display)
- Actual temperature of the hot water in the DHW system (simple display)
- Ambient temperature (simple display)
