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
voltage 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).
If the Comando Amico Remoto
other On/Off chrono-thermostat is used, arrange two
separate lines in compliance with current regulations
regarding electrical systems.
No indoor unit pipes must ever be used to earth the elec-
tric system or telephone lines.
Ensure elimination of this risk before making the indoor
unit electrical connections.
