Select the operating modes using the AUTO - %- $- . keys. 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. ZSee: Programming.

`Key %= Daytime mode

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

`Key $= Night mode

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

`Key = Tank load enabled mode

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.

ZSee: Table of "User" setting.

Key # is used to cut off the heating and, if the corresponding function is activated, to switch to Cooling mode.

ZSee 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.

Theonly:MIT interior hydraulic module operates in COOLING mode

-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.
