PERATING

Operating the unit comes down to operating the digital controller.

Never let the digital controller get wet. This may cause an electric shock or ﬁre.

Never press the buttons of the digital controller with a hard, pointed object. This may damage the digital controller.

Never inspect or service the digital controller yourself, ask a qualiﬁed service person to do this.

THE

DIGITAL

UNIT

CONTROLLER

Features and functions

The digital controller is a state of the art controller that offers full control over your installation. It can control a cooling/heating and a cooling only installation.

Both installations are available in multiple versions which vary in capacity.

NOTE

Descriptions in this manual that apply to a speciﬁc installation or that depend on the installed equipment, are marked with an asterisk (*).

Some functions described in this manual may not be available or should not be available. Ask your installer or your local dealer for more information on permission levels.

Basic controller functions

The basic controller functions are:

Tu r ning the unit ON/OFF. Operation mode change-over:

- heating (refer to "Heating operation (h)" on page 4),

- cooling (refer to "Cooling operation (c)" on page 4),

- quiet mode (refer to "Quiet mode operation ( s )" on page 4), Selection of features:

- quiet mode (refer to "Quiet mode operation ( s )" on page 4),

-weather dependent control (refer to "Selecting weather

dependent set point operation (heat pump models only)" on page 4).

Temperature set point adjustment (refer to "Controller

operations" on page 4).

The digital controller supports a power cut off of maximum 2 hours. When autorestart is enabled (see "Field settings" on page 9) this allows a power supply shut down of 2 hours without user intervention (e.g. beneﬁt kWh rate power supply).

Clock function

The clock functions are:

24 hour real time clock. Day of the week indicator.

Schedule timer function

The schedule timer function allows the user to schedule the operation of the installation according to a daily or a weekly program.

3 Use the bi or bj button to adjust the day of the week.

Each time the bi or bj button is pressed the next or previous day is displayed.

4 Press the < button to conﬁrm the current set time and day of the

week. To leave this procedure without saving, press the pr button.

If no button is pressed for 5 minutes the clock and day of the week will return to their previous setting.

NOTE

The clock needs to be set manually. Adjust the setting when switching from summertime to wintertime and vice versa.

Setting the schedule timer

Description of the operation modes

Controller operations

Heating operation (

In this mode, heating will be activated as required by the water temperature set point. The set point can be set manually (refer to

"Manual operation" on page 4) or weather dependent (refer to "Selecting weather dependent set point operation (heat pump models only)" on page 4).

Startup (d)

At the start of a heating operation, the pump is not started until a certain refrigerant heat exchanger temperature is reached. This guarantees correct startup of the heat pump. During startup, icon

d is displayed.

Defrost (d)

In heating operation, freezing of the heat exchanger may occur due to low outdoor temperature. If this risk occurs, the system goes into defrost operation. It reverses the cycle and takes heat from the indoor system to prevent freezing of the system. After a maximum of 8 minutes of defrost operation, the system returns to heating operation.

NOTE

Defrosting stops:

■ when switching between cooling and heating,

■ at a low outdoor temperature and a low

temperature of the incoming water,

■ when the desired defrost temperature is reached, i.e. defrost stop temperature (contact your local dealer).

Heating operation restarts automatically when the water temperature is above the defrost stop temperature.

NOTE

Heating operation is not possible if the installation is a "cooling only" installation.

Manual operation

In manual operation, the user manually controls the settings of the installation. The last setting remains active until the user changes it or until the schedule timer forces another setting (refer to "Schedule

timer operation" on page 5).

As the controller can be used for a wide variety of installations, it is possible to select a function which is not available on your installation. In that case the message n will appear.

Switching on and setting cooling (c) and heating (h) 1 Use the = button to select cooling (c) or heating (h).

Icon c or h appears on the display as well as the corresponding water temperature set point.

2 Use the bi and bj buttons to set the desired water

temperature.

•Temperature range for heating: 25°C to 55°C

•Temperature range for cooling: 5°C to 22°C

NOTE

3 Switch on the unit by pushing the

In heating mode (h), the water temperature set point can also be weather dependent (icon

This means that the controller calculates the water temperature set point based on the outdoor temperature.

In this case, instead of showing the water temperature set point, the controller shows the "shift value" which can be set by the user. This shift value is the temperature difference between the temperature set point calculated by the controller and the real set point. E.g. a positive shift value means that the real temperature set point will be higher than the calculated set point.

The operation LED 0 lights up.

a is shown).

Cooling operation (c)

In this mode, cooling will be activated as required by the water temperature set point.

NOTE

■ The cooling temperature set point can only be set manually (refer to "Manual operation" on page 4).

■ Switching between heating and cooling operation can only be done by pressing the = button or by an external room thermostat. (Provided the unit is not a "cooling only" unit)

Quiet mode operation (s)

Quiet mode operation means that the unit works at reduced capacity so that the noise produced by the unit drops. This implies that the indoor heating and cooling capacity will also drop. Beware of this when a certain level of heating is required indoors.

Tw o quiet modes are available.

NOTE

When the unit is connected to an external room thermostat, buttons = and y are not operable and the icon e is shown. In this case, the external room thermostat switches the unit on or off and determines the operation mode (cooling or heating).

Selecting quiet mode operation (s) 1 Use the s button to activate quiet mode operation (s).

Icon s appears on the display. If the controller is set in permission level 2 or 3 (refer to "Field

settings" on page 9), the s button will not be operable.

Selecting weather dependent set point operation (heat pump models only)

1 Press the ba button to select weather dependent set point
