1.10 ROOM CHRONO-THERMOSTATS
(OPTIONAL)
The indoor unit is prepared for the application of room chro-
no-thermostats or remote controls, which are available as optio-
nal kits (Fig. 9).
A maximum of 3 temperature controllers can be applied directly
to the appliance.
All Immergas chrono-thermostats are connected with 2 wires
only.
Carefully read the user and assembly instructions contained in
the accessory kit.
Carry out the connection as indicated (Fig. 8).
Disconnect power to the unit before ma-
king any electrical connections.
On/Off Immergas digital chrono-thermostat.
The chrono-thermostat allows:
- set two room temperature value: one for day (comfort tempera-
ture) and one for night (reduced temperature);
- set a weekly programme with four daily switch on and switch off
times;
- selecting the required function mode from the various possible
alternatives:
• manual mode (with adjustable temperature);
• automatic mode (with set programme);
• forced automatic operation (momentarily changing the tem-
perature of the automatic program).
The chrono-thermostat is powered by two 1.5V LR 6 type alkaline
batteries.
On/Off chrono-thermostat electrical connection (Optional).
The operations described below must be
performed after having removed the vol-
tage from the appliance.
On/Off ambient thermostat or chrono-thermostat: must be con-
nected to the 40-1 / 41 terminals, eliminating the X40-1 jumper
for zone 1 and 40-2 / 41 for zone 2 and 40-3 / 42 for zone 3.
Make sure that the On/Off thermostat contact is of the "clean"
type, i.e. independent of the mains voltage, otherwise the P.C.B.
would be damaged.
The connections must be made on the terminal board inside the
appliance's control panel (Fig. 8).

1.11 MODBUS TEMPERATURE AND
HUMIDITY ROOM PROBES (OPTIONAL)
The temperature and humidity probe is used to detect room hu-
midity and to calculate the relative dew point by regulating the
flow temperature during the cooling phase.
Connect the appliance as shown (Fig. 8).
