The following section details how to define fan speed.

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.

Temperature control
The purpose of this thermostat is to keep the room at the
temperatureestablishedbythe setpoints.When operatingin
AUTOor AUTOPROG,the heat andcool set pointsare used.
However,when operating inHEATtheheatsetpointsareused
only, and when operating in COOL the cool set points are
used only.When the temperature between the real tempera-
tureand theset pointis morethan 0.2°C,the firststageY1 is
activated. If after a while (depending upon the temperature
control operating modeTURBO, NORMAL, ECONOMY) the
temperature has not recovered, the second stageY2 is acti-

vated. If the set point is still not reached, and after a certain
period of time, the third stage W is activated (in HEAT only).
When the real temperature is close to the set point in 0.1° C,
W is deactivated andY2 is deactivated at the set point tem-
perature,andwhen thesetpointtemperatureis surpassedby
0.1° C,Y1 is deactivated.
Operating with temperature probe S-4 is a special case.The
temperatureis received bycommunication with themachine.
In this case, the temperature is in steps of 0.5° C and, there-
fore,controlisdifferent.Whenthedifferencebetweentheroom
temperature and the set point is greater than or equal to the
set point temperature, the first stage is activated.The same
as in the previous case, if after a while the set point is not
reached, stages Y2 and W are activated successively (in
HEAT).Oncethetemperaturereachesthesetpoint,thestages
go off.
Communication
The DPC-1 thermostat operates by communication only.
By communication it is possible to monitor the status of the
thermostat,whilebeingableto programsame.Inotherwords,
allparameters thatare changeablebymeans ofkeys canbe
modified by means of communication, except for the tempo-
raryparametersandthe numberofdaysinunoccupiedmode.
Therearealso6timescheduleprofilesthatcanbeprogrammed
by means of communication only, and these go from 7 to 12.
If not programmed or used, these profiles are not displayed
ontheprofileprogramming menuwhenaccessedthroughthe
keyboard.
Installation instructions
It is recommended that the installation be carried out by a
qualifiedcontractor.
Location
To assure adequate operation, this thermostat should be in-
stalledon anindoor wall, ina frequentlyoccupied area ofthe
building. Furthermore, it should be at at least 46 cms. from
any outdoor wall, and at approximately 1.5 m. above floor
level,in anareawith free airflow and atan average tempera-
ture.The following locations should be avoided:
- Behind doors or in corners with no free air flow.
- Spots where direct sunlight or heat generated by other ap-
pliancesmay alterthe control operation.
- Onan outdoorwall.
- Nexttooralignedwithair conditioning dischargegrids,stair-
wellsor doorsleadingoutdoors.
- Spots where its operation can be affected by gas or water
pipes, or hot air chimneys in adjacent areas or any other
areawithout environmentalcontrolbehind thethermostat.
- Spotswhere itsoperation can beaffected bythe supplyair
of any adjacent unit.
- Near sources of electric interference, such as arch relay
contacts.
Basic elements
This thermostat comprises three basic parts:
- Hingedfront cover.
- Frontpanel.The operating andcontrolbuttonsare foundin
