8. USER SECTION: OPERATION
8.10 Relaunch circulator
Recipe 1
The voltage output P1 of the TERMINAL BLOCK PCB is arranged to supply
(phase L) one relaunch pump.

P1 in
The relaunch pump is powered whenever the circulator inside the PdC is
active.
Recipes 2, 10 and 13
The voltage output 203 (P2) of the TERMINAL BLOCK PCB is configured to
supply (phase L) one relaunch pump.

The relaunch pump is powered when the circulator inside the PdC is
active, except if it is heating the DHW.
In addition, by configuring the C404 Parameter, you can distinguish the
following cases:
- C404=0 (factory), relaunch pump active only for the radiant system;
- C404=1,relaunch pump active for both the radiant system and the fancoils
(Set Point 2 consent);
- C404=2,relaunch pump active only for fancoils (Set Point 2 consent);
The status of the relaunch pump is visible on Parameter L244. In addition,
on the SMART-MT, icon # 1 becomes intermittent.

8.11 Additional heater
The PdC is able to manage the consent to an additional heater that can
intervene to support it.
The status of the additional heater consent is visible on Parameter L245.
In addition, icon no. 5 lights up on the SMART-MT.
Recipe 1 and 10
The voltage output 200 (R1) of the TERMINAL BLOCK PCB is arranged
to supply (phase L) one electrical heater integrating the PdC, or
alternatively consent to a boiler.
WARNING:
If an electric heater is used, inlet P0 must also be supplied via
outlet 200 (R1). This is to ensure the activation of the PdC internal
circulator when the heater is powered.
