Various settings are possible with this type of thermostat. Read the
installation manual carefully before installation. For proper operation,
please check the parameters below and adjust if necessary:
P01: 0 (system type)
P02: 1 (manual change-over heat/cool) *
C15: 2 V (minimum fan speed)
C16: Maximum fan speed (V) **
*
Heating or cooling modes are selected by keeping the button
depressed for some seconds, until the display shows one of the
following texts which indicates the current mode:
HEA : Heating mode
COO : Cooling mode
Then, by pressing the arrow keys, the user can change the desired
operating mode.
**
With the Comfort Line and the Major Line with ducting: the capacity (air
volume) depends on the resistance in the duct and the grilles. In
most cases, the maximum speed should be set between 5V and 8V.
Explanations:
E/I = Change-over contact heating/cooling *
RDC = Contact to activate the “Economy” function (set P18) *
SM = Supply water sensor **
SA = Room sensor (if applied P11 = 1) **
CF = Window contact * and **
XB, TB, A1F / X2 = terminals fan coil unit
*
The functions of these outputs can be changed with parameters C17,
C18 en C19. See for more information the installation manual.
**
Use a separate shielded cable (see for more information the
installation manual)
