Supplementary accessories

• For heating circuits with or without mixer:
– Heating pump; connection to PC1
– Flow temperature sensor – system for low loss header
(optional; not possible with all user interfaces);
connection to T0
– Temperature switch; connection to MC1; when limit
temperature is exceeded, power supply to terminal 63
- PC1 is interrupted; if there is no temperature switch in
the heating circuit without mixer or in the constant
heating circuit, connect jumper ( Fig. 1 [2],
page 91) to MC1 (included in standard delivery).
• Additional accessories for heating circuit with mixer:
– Mixing valve actuator; connection to VC1
– Flow temperature sensor in assigned heating circuit;
connection to TC1
• Additionally, for a constant heating circuit:
– External signal for heat requirement; connection to
MD1 (the pump is only switched on if the external heat
requirement is enabled on the user interface)
– Mixing valve actuator (optional); connection to VC1
– Flow temperature sensor in assigned heating circuit
(optional); connection to TC1
• For cylinder primary circuit (e.g. after low loss header):
– Cylinder primary pump; connection to PC1; connect
jumper ( Fig. 1 [2], page 91) toMC1
– DHW circulation pump (optional); connection to VC1
(terminal 43: DHW circulation pump phase/terminal
44: not assigned)
– Flow temperature sensor for low loss header (optional;
not possible with all user interfaces); connection to T0
– Cylinder temperature sensor; connection to TC1.
Installation of additional accessories
▶ Install additional accessories according to legal
requirements and the instructions supplied.
