DOMINUS BOILER ADJUSTMENT (EXCLUDING VICTRIX MAIOR, EXTRA AND SUPERIOR).
The below-described adjustment functions are always enabled if a Room Thermostat, or similar, is connected to the device; if the Dominus device is connected to a CARV2, the below-described functions are only enabled if the device is activated (see Fig. 19).
2.1 DOMINUS CONFIGURATION.
From the “Boiler” page, pressing the “Config. Dominus” button (Ref.12 Fig. 16) displays the following page from whence you may edit the main parameters set in the device. After making any changes, press the button (Ref.1 Fig.14) to send them and make them active.
- Climatic curve: in the presence of external probe, change the set flow temperature (see fig. 15), as per standard set at 3.
- CH temp. offset: constant that can be regulated from -15°C to +15°C and in the presence of the external probe (optional), modifies the set flow temperature (see fig. 15) set to 0°C as per standard.
- External probe use: enables/disables the operation curve (Fig. 15) if the external probe is present.
- Modulation use: allows enabling (ON) or disabling (OFF) the operation of the flow temperature modulation. Set at ON, the flow temperature will be varied depending on the room temperature set. Set at OFF, the flow temperature will be kept constant until the desired room temperature is reached. (Setting to be made on systems with zones control unit). N.B.: if an outdoor temperature probe is present, the flow temperature will be set depending on the relative functioning curve.
- Hysteresis temperature: with room probe enabled, it indicates the temper- ature added to the set, above which the request to the generator is removed.
- Room probe use: allows to activate or deactivate the room probe. On the basis of the parameter setting, it will be possible to regulate the following options: – ON (standard value); it is possible to select a correction factor of the room probe reading and change the modulating function. – OFF, the system will not function, regulating the room temperature but only depending on the time program set. In this case the room anti-freeze function is not assured.
- Building size/type: adjustable from 1 to 20, standard set at 10. It establishes the system reaction speed according to the type of system present. For example:
Value System type 5 System with little heat inertia 10 System with normal dimensions with radiators 20 System with heat inertia (e.g. floor-standing system) - NTC use (room/outdoor temp.): allows selecting the use of the room sensor or of the external probe.
- Room antifreeze use: allows enabling/disabling the antifreeze function.
- Room antifreeze temperature set: allows setting the room temperature for activation of the anti-freeze function. Can be regulated from 0°C to 10°C and is set at 5°C as standard.
- Set minimum central heating (SetMinCH): allows to regulate the central heating flow minimum temperature value. Moreover, this value is used to calculate the curves used for the external probe. Values that are too high can cause flow temperatures that are too high on average for room central heating.
- Set maximum central heating (SetMaxCH): allows to regulate the maximum CH flow temperature value.
- Factory data reset.
