8.15 Electrical powers
Recipes 10 and 13
Instructions regarding the configuration and management of electrical
powers are can be found in the Febos-Crono and Febos-Energy manuals.
This chapter only shows the electrical connections to the TERMINAL
BLOCK PCB.
8.15.1 Power absorbed by MIRAI-SMI
Recipe 10
The input 103 (F+ / F-) of the TERMINAL BLOCK PCB is configured to con-
nect the pulsed output of the electrical energy meter, placed in series with
the power supply of the MIRAI-SMI.
In case of single-phase Heat Pump, connect the counter (Code 07245360)
terminal 20 (counter) to terminal F+ (TERMINAL BLOCK PCB)
terminal 21 (counter) to terminal F- (TERMINAL BLOCK PCB)

8.15.2 Power absorbed by Eco Hot Water
Recipes 10
The input 104 (G+ / G-) of the TERMINAL BLOCK PCB is configured to con-
nect the pulsed output of the electrical energy meter (Code 07245360),
placed in series with the Eco Hot Water supply.
Connect the counter terminals 20 and 21, respectively, to terminals G+
and G- of the TERMINAL BLOCK PCB.

8.16 Dehumidifier
Recipes 10 e 13
The voltage output 205 (U1) of the TERMINAL BLOCK PCB is configured to
power (phase L) the consent to a dehumidifier.
NOTE:
If you are using a dehumidifier where a clean contact is required, use a
support relay.ilizza un deumidificatore in cui è richiesto un contatto pulito,
utilizzare un relè d'appoggio.
8.16.1 Operation of independent dehumidifier (C406 = 1)
By configuring parameter C406 = 1, the dehumidifier operation is indepen-
dent from that of the HP. In case of activation of the humidistat consent of
the Febos-Crono, the output 205 is activated, regardless of the operating
mode (Cooling or Heating) of the MIRAI-SMI.
The activation of output 205 is the only action performed by the HP.
8.16.2 Operation of dependent dehumidifier
from the HP (C406 = 0)
By configuring parameter C406 = 0, the operation of the dehumidifier
depends on the production of cold water from the HP. In case of activation
of the humidistat consent of the Febos-Crono, the output 205 is activated
only if the operating mode of the MIRAI-SMI is in Cooling mode. If the
MIRAI-SMI is not already producing cold water, the activation of the
internal circulator is forced and the compressor modulates to reach the
target temperature set in parameter C553.
8.16.3 Operation of dehumidifier depending
on the HP + Booster fancoil (C406 = 2)
By configuring parameter C406 = 2, you have the same operation as
C406 = 0, to which is added the activation of output 205 in the event of a
Febos-Chrono Boost call, but only in Cooling.
8.16.4 Operation as a booster fancoil (C406 = 3)
By configuring parameter C406 = 3, output 205 is activated in the event of
a Febos-Crono Boost call, both in Cooling and Heating.
