Available programs
OPTIMISER ® digital regulator code 152200 can be used in accordance with 6 different system configurations (programs), comprising a basic
factory-set configuration and 5 optional configurations selectable by means of the table shown below and activatable by means of the dipswitches
on the regulator. To access the dipswitches open the cover under the display. The regulator is supplied with the factory settings and probes
required to perform basic program 4.
Location of cable glands
When making the electrical connections, observe the following sequence for wiring the terminal board.
- If the regulator is to be wall mounted with the consequent use of the supplied cable glands and downward cable outlet, regulations require that just
one cable can transit through each hole of the cable gland, therefore a maximum of 6 high voltage cables and 6 low voltage cables can be utilised.
It is therefore recommended to comply with the following table of connections and use two additional junction boxes complete with suitable inlet and
outlet cable glands, in accordance with the diagram given. The earth connection must be made in the junction box.
- If the regulator is installed in an electrical cabinet, the cable outlet must be via the openings at the rear of the unit, always keeping high and
low voltage cables separated. The earth connection must be made in the electrical cabinet.
NOTE The probes are all of the NTC type (grey cable) except for probe Sol1 utilised by solar programs 7, 8 and 9, which
is type Pt1000 with
red cable.

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).
