These keys simultaneously control all circuits connected.
To modify the operating mode (AUTO, Daytime
%
or Nighttime
$
)
for only one of the heating circuits, use the remote control
corresponding to this circuit.
An override applied to the remote control takes priority over the
override selected on the central regulator.

AUTO key = Automatic mode
Heating according to the time programme.

= Daytime mode
The heating operates according to the Daytime temperature,
independently of the timed programmes.

The heating operates according to the Nighttime temperature,
independently of the timed programmes.
`
Key

Domestic hot water production is enabled, independently of the time
programme.

Key
.
= Antifreeze mode
The heating is off but the installation is monitored and protected
against frost.
The antifreeze mode protects:
- The installation if the outside temperature is lower than 3°C
(factory setting).
- The room temperature if a remote control is connected and the
room temperature is lower than 6 °C (factory setting).
Antifreeze protection is guaranteed for each heating circuit,
regardless of the setting on the corresponding room
temperature sensor. The room temperature in "antifreeze"
mode is preset to +6 °C. This value can be modified if a room
sensor is fitted.

is used to cut off the heating and, if the corresponding

See menu #HEAT PUMP, parameter REFR.:
This function is independent of the "automatic heating shutdown"
function in summer when the outside temperature exceeds the
outside temperature for "heating shutdown".
When the heating is off during the "summer" mode, the pumps
are started up once a week for one minute in order to prevent
fouling.
The MIT interior hydraulic module operates in COOLING mode
only:
- During the DAY period on timed programmes A and B,
-
and
if the outside temperature is higher than the instruction SUM/
WIN + SUM/WIN BAND (Factory setting: 22 + 4 = 26 °C).
Do not use or modify this programme when operating with
the QUADROPAC domestic hot water tank.
