The following section details how to define fan speed.
Ventilation
Therearetwo possibleconfigurations:withor withoutspeeds
(definedbypin 6 ofthemicro-switch.OFFindicates 3 speeds,
ONindicatesnospeeds;seeConfigurationofmicro-switches).
If there is communication between the thermostat and the
controlboard, thesetting of 1or 3speedsis carriedout auto-
matically.
Configurationwith nospeedsallows choosing between:
- ON:Always operative.The fan appears with no wind icon.
- AUTO:Operativeasneeded, upon demand.Thefanappears
with no wind icon, but with AUTO below same.
Configurationwith speeds allowschoosingbetween:
- ON:Thefanappearsandthewind icons indicatethespeed.
- AUTO:Operativeasneeded, upon demand.The fanappears
with AUTO below same, and the wind icons indicate the
speed.
Available speeds are as follows:
- HIGH:Maximum speed.Threewind icons.
- MED.:Mediumspeed.Twowind icons.
- LOW:Minimum speed.Onewind icon.
- AUTO:Automatic.The systemselects fanspeed automati-
cally with regard to the set point temperature. The AUTO
iconflashes,appearingwithoutwind icons.When thediffer-
ence is below 1° C, speed is LOW; when between 1 and
3°C,thespeed is MED;andabove3° C, thespeedisHIGH.
Fan configuration can be carried out in two different ways:
- Bymeans ofthe programmingmenu.
- Pressing the key.
Theprogramming menuconfigures thefan foreach occupa-
tion status:occupied (comfort or day), stand-by (economy or
night) and unoccupied.This program will be detailed further
below.
Pressing the key gives access to the Setting mode,
thatlasts 5seconds.Pressing thekey once doesnot change
the present status; this is displayed, with the fan flashing.
Pressingconsecutively changesfan operation.
In the AUTO PROG mode, the change over of fan operation
with the key is temporary. When the set point is
changed,the originalprogrammed valueis recovered.Upon
resettingthefan,theremainingairconditioningmodeschange
theirprogrammedvalues.
The vent only mode is nothing but the setting of the fan to
OFF mode. Changes made in the OFF mode do not remain
whenexiting thismode.
Operating modes
There are three different thermostat operation modes avail-
able:Normal Mode,SetMode andProgramMode.
Normally, the thermostat will be set to Normal Mode, ex-
ecuting the programmed temperature control algorithm and
time schedule profile (if in the
AUTO
PRO
G
air conditioning mode).
The keys correspond to the symbols printed on them.
When, in the Normal Mode, the key to change the air condi-
tioningmode, occupationstatus,set point temperatureor fan
operationis pressed,thethermostat will goto Setting Mode,
which it will not exit until five seconds after having pressed
the last setting key.This will validate all changes made in the
setting process. In the setting mode the parameters that are
changed flash: If the mode is changed, it flashes. If set point
oroccupationstatusarechanged,thethermostaticonflashes,
since the system set points are being changed. And if fan
operation is changed, it flashes as well.
In Normal Mode, pressing the
PROG
key accesses the Pro-
gramming Mode, where we will se the programming menu
that allows changing the different thermostat parameters. In
this mode, the keys change the functions associated with
their symbols (operational keys: next, back, accept and de-
lete).If nootherkey ispressedin 30seconds,the thermostat
goes back to the Normal Mode.

Pressing one of these two keys in Normal Mode accesses

increased or decreased in steps of 0.5° C or 1° F.
If in AUTO PROG MODE icon will appear flashing, indi-

valid until a change is made in the occupation of the time
schedule profile.When this change in the time schedule pro-
file is made, the programmed set points are restored.Also, if
achange is madeinthe occupationstatusmode(Day/Night),
theprogrammed setpointis re-established.
In the remaining air conditioning modes these changes are
made on the programmed set point values by means of the
programmingmenu.

There is a total of six programmable temperature set points
thatcorrespondto theheatandcool modes ofthethreeoccu-

Thereshould be a1°difference betweentwoconsecutive set

thanone degree centigradefromthe followingsetpoint, it will
be"dragged" soasto avoidthe unsuitability ofthe set points.
When this happens, the thermostat will flash the icon of the
occupation mode of this set point. Upon exiting the Setting
Mode these flashes and icons of the dragged set points dis-
appear.
