Display and commands General functions Display The regulator is equipped with a display to read and program the Optimiser control parameters, such as cut-in temperatures, function activation delay times, thermal disinfection programs, solar system control, etc. All the system’s functional parameters can be configured to match individual requirements by means of the “Select”...
Programs 1,2 and 3 (not listed in the table but however available) are functionally equivalent to programs 7,8 and 9 respectively but without thermal solar components. For specific setting (dipswitches and probes to be used) please see instruction sheet 28169 (www.caleffi.com).

*Operating logic of program “management of inertial water storage in parallel on the heating system”. In accordance with construction and system regulations or depending on system management requirements it may be necessary to use an inertial water storage on the heating system. The regulator is supplied as standard with the parameters and probes required to manage a heating system with inertial water storage in parallel on the heating system.
The inertial water storage in parallel is managed in accordance with the logic described on page 6. By means of diverter valve V5 (not supplied in the pack, e.g.: Caleffi 6443..3BY series + relay box code F29525) the regulator manages all phases of loading and unloading of the water storage, which is kept closed only if the gas boiler has been activated.

The inertial water storage in parallel is managed in accordance with the logic described on Sun. 10-12 page 6. By means of diverter valve V5 (not supplied in the pack, e.g.: Caleffi 6443..3BY series Mon. and Wed. + relay box code F29525) the regulator manages all phases of loading and unloading of the water storage, which is kept closed only if the gas boiler has been activated.
