1.11 ROOM CHRONOTHERMOSTATS
OPTIONAL
e indoor unit is prepared for the application of room
chrono-thermostats or remote controls, which are available as
optional kits (Fig. 12).
A maximum of 2 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.
Disconnect power to the unit before
making any electrical connections.
On/O Immergas digital chrono-thermostat.
e 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 o
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).
e chrono-thermostat is powered by two 1.5V LR 6 type alkaline
batteries.
On/O chrono-thermostat electrical connection (Optional).
e operations described below must be
performed aer having removed the
voltage from the appliance.
On/O 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/O thermostat contact is of the “clean”
type, i.e. independent of the mains voltage, otherwise the P.C.B.
would be damaged.
e connections must be made on the terminal board inside the
appliance’s control panel (Fig. 11).
1.12 MODBUS TEMPERATURE AND
HUMIDITY ROOM PROBES OPTIONAL
e temperature and humidity probe is used to detect room hu-
midity and to calculate the relative dew point by regulating the
ow temperature during the cooling phase.
Connect the appliance as shown (Fig. 11);
