Automatic air purging valves should be placed at each high point of the installation, and manual air purging The PRIMO Pilot must be placed in an area which is free from frost valves should be installed on each radiator.
4.2.1.6 - Frost Protection 4.2.1.9.1 - Filling water Frost protection is necessary if the PRIMO Pilot is switched off during The materials used for producing a heating circuit are of diff erent the winter months (ex: secondary residence, etc...). natures. Instances of corrosion may occur through galvanic coupling in both new and existing installations.
Heat Pump must, consequently, be lower than 2.5 bars. Example : If the Heat Pump is positioned 5m below the PRIMO Pilot, the pressure reading on the PRIMO Pilot would be 0.5 bars less than the real pressure of the water in the Heat Pump.
