Various settings are possible with this type of thermostat. Read the installation manual carefully before installation. For proper
operation, check the parameters indicated per system and adjust them if necessary.
To access the configuration menu, simultaneously press the and buttons for a few seconds until “COn”
(configuration) appears on the display. Once entered in configuration menu, pressing scrolls through the
various parameters, identified with P and the parameter number, from P01 to P25.
When scrolling the parameters pressing button or or displays its current value.
To change the value, when it is displayed, press button or .
The configuration end is displayed with “End”. Press again to save the configuration and return to normal operation.
The extended parameters C01-C23 allow an advanced thermostat configuration. When the display shows “COn“ at
configuration start or “End“ at configuration end, press the button to access the extended parameters.
APPLICATION
Thermostat type: 99DA-SEI-EC01

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)

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 (automatic change-over heat/cool)
C01: 17 (if water temp. lower than this value →cool) *
C02: 30 (if water temp. higher than this value →heat) *
C15: 2 V (minimum fan speed)
C16: Maximum fan speed (V) **
* Install a water temperature sensor (SM ***) on a pipe where the
water supply can be measured and connect it to terminals 13 and 14.
** 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.
