If the security valve on a cooling co
il against overheating is installed, it is possible not to use the floating back flap at the bypass.
On special user demand the installation can be expanded with accumulation tanks (1,2 or 3 pieces even), room and outside temperature sensor or thermal outlet
protection. There’s also a possibility to combine two boilers within cascade. Such modification must be performed based on separate documentation of installation
designed by the authorized designer.
