Selecting local or remote on/off control

User parameter 

h7

  in combination with the remote on/off switch

(installed by the customer) allows the user to switch the unit on
without using the 

I

 or 

Y

 key on the controller.

When user parameter 

h7

 is set to 

0

 (= No), the unit can only be

switched on by means of the 

I

 or 

Y

 key on the controller.

When user parameter 

h7

  is set to 

1

  (= Yes), the unit can be

switched on by means of the remote on/off switch and the 

I

 or

Y

 key on the controller.

To select local or remote on/off control, proceed as follows:

1

Enter the list of user parameters.

Parameter code 

:d

 appears on the display.

2

Select parameter code 

h7

 using the 

A

 and/or 

Z

 key.

3

Press the 

R

 key to switch to the parameter value.

4

Select the appropriate setting using the 

A

 and/or 

Z

 key.

5

Press the 

R

 key to return to the list of parameter codes.

6

To adjust or to consult other user parameters before saving the
modifications, select another user parameter using the 

A

 and/

or 

Z

 key and then repeat from instruction 3 onwards.

7

To  save the modifications, press the 

E

  key.  To  cancel the

modifications wait approximately 40 seconds.

In the first case, the controller saves the changes, leaves the list
of user parameters and returns to normal operation, displaying
the inlet water temperature.
In the second case, the display starts flashing. Approximately
40 

seconds later, the controller leaves the list of user

parameters without saving the modifications. The inlet water
temperature reappears on the display.

Locking the controller keyboard

Once user parameter 

h9

 is set to 

0

, the following advanced features

can no longer be carried out by means of the controller:

modifying direct and user parameters (parameters can be
displayed but not modified),

selecting cooling or heating mode,

resetting the timers.

When user parameter 

h9

 is set to 

1

, the above-described advanced

features can be carried out using the controller.

To lock or unlock the controller keyboard, proceed as follows:

1

Enter the list of user parameters.

Parameter code

In the second case, the display starts flashing. Approximately
40 

seconds later, the controller leaves the list of user

parameters without saving the modifications. The inlet water
temperature reappears on the display.

Defining the unit's serial address

To  control the unit from a supervisory system, an address card
(optional module) should be installed in the unit. The unit's serial
address required for communication with the supervisory system is
defined by parameter 

ha

.  The default, limit and step values for the

serial address are:

Default value

1

 

Limit values

1

  to 

16

Step value

1

To define the unit's serial address, proceed as follows:

1

Enter the list of user parameters.

Parameter code 

:d

 appears on the display.
