Figure 9: Simplified heating diagram of configuration D. The explanatory notes are identical with configuration A. Block P refers to a
three-phase electrical cartridge heater used as a bivalent heat source and block R refers to a three-phase electrical cartridge heater
intended for using the excess energy by means of the WATTrouter. This cartridge heater is located in the bottom part of the storage
tank so that most of the tank volume can be used for the accumulation of the excess energy.
CONNECTION OF THE OUTDOOR UNITS OF THE HEAT PUMPS
Figure 10: Electrical diagram showing the connection of the controller with a single-phase Fujitsu outdoor unit via the UTI-INV-XX
control module from the company Impromat Klima s.r.o. The connection of a three-phase unit is analogous, see the installation
handbook for the device.
Caution: This diagram is illustrative, it is necessary to always perform the connection according to the
installation handbook for the control module of the outdoor unit, the connection may change!
Figure 11: Electrical diagram showing the connection of the controller with the single-phase Mitsubishi outdoor unit via the PAC-IF011B-
E control module. The proper function of the connection requires the correct setting of the DIP switches according to the documentation
for this module. The KA1 relay is used for unblocking the operation of the unit on terminals 1 and 2 of the TB142 connector, it must be
done in this way by the break contact. In order to operate KA1 we will use the “Status duplicate 1” block (EXT1 -> Tr2). Terminals 3 and 4
of the same connector are permanently connected which makes the unit firmly set in the heating mode. The connection of a three-
phase unit is analogous, see the installation handbook for the device.
Caution: This diagram is illustrative, it is necessary to always
perform the connection according to the installation handbook for the control module of the outdoor unit, the connection may change!
