1.3. Introduction
TermoMini boilers are economical central heating boilers that can be used as an independent or additional source of heat. TermoMini boilers offer you a possibility to reduce the power of the heater if necessary. The power can be easily reduced through the control panel. This way it is possible to adapt the boiler to the utmost to circumstances on the spot. The boiler operates on a principle of rapid heating smaller water quantities, so that exploiting energy is already 100%. TermoMini boilers are used for radiator and floor heating. Temperature operation area is from 20°C to 90°C. TermoMini boilers are designed in such way that in apartment-contained central heating they can fit well with your furniture.
1.4. Frost protection
The software in control panel provides boiler frost protection. When frost protection is controlled for entire central heating system by room thermostat, please consult room thermostat manuals for more details.
