User instructions - General information.
A) What HC10B does
PHC10B is a digital thermostat for precise control of electric underoor heating.
PHC10B starts automatically in Quickstart = Manual mode and oor sensor
PHC10B can also perform night and day setback in three different ways
B) IMPORTANT!
Important information before connecting the underoor heating
PTo ensure optimum service life of the underoor heating, the material in which
the heating system is laid must be allowed to dry for a minimum of 28 days
before switching on the heat.
PA new installation of HC10B and underoor heating must be carried out by an
authorised electrician.
PExchanging an HC10B, is allowed to do by the end-user in most countries.
PHC10B must not be covered.
C) Programs in HC10B
C.1) Quickstart
PSwitch on and the underoor heating will start up.
PThe temperature is set to 21°C
LThe temperature can be altered with [q] or [p]
The display shows the set temperature
PThe oor sensor will automatically start operation
C.2) Night and day setback programs
PHC10B holds three different night and day setback programmes.
PThey each control the temperatures and time settings. i.e. low temperature at
night and during working hours, higher temperature at morning and evening.
PFor each program the starting time and temperature are determined. Start times
and temperatures are set at the factory, but can be changed as required. The
factory setting is shown in Table 1.
PNight and day setback ensures minimum power consumption. With optimum
adjustment of the underoor heating the average temperature can be dropped
by up to 3°C, giving potential power savings of up to 15%. The savings will
naturally depend on the circumstances and on what you want from the
underoor heating.
PMax. and min. limits are in all programs Max: 27°C Min.: 15°C.
Program 1: Settings for Monday to Friday, and settings for Saturday and Sunday.
Program 2: Settings for All Weekdays.
Program 3: Settings for Each Day of the Week separately.
Table 1: Factory setting for night and day setback.
Times and temperatures can be changed as required. See section 3.4) and 3.5).
Program 1: Settings for Monday to Friday, and settings for Saturday and Sunday.

D) Floor and room sensors
Two sensors, a oor sensor and a room sensor provide HC10B with feedback on
the current temperature in the room or the oor. The feedback from the sensors is
necessary to maintain the desired temperature in the room.
The sensors can be used separately or together.
PFloor sensor (FL)
PRoom sensor (RO)
PCombined use of room and oor sensor (CO). In (CO) setting, the room sensor
controls the room temperature, while the oor temperature*) is simultaneously
monitored by the oor sensor. The HC10B monitor is set to a desired minimum
temperature and a desired maximum temperature. The factory settings are 27°C
and 15°C respectively.
(CO) should be selected when heating is installed under a timber floor.
*) Temperature measured by floor sensor.
E) HC10B backup battery
HC10B is equipped with a battery ensuring around 100 hours’ backup. If the
power has failed and the backup battery is active, the display will show OFF. If the
thermostat has been without power for more than around 100 hours, the backup
battery will be empty.
When the power returns again, HC10B will start up with the factory settings
Quickstart and 21°C.
Any changes made to the programs will be lost.

temperature in the oor. Temperature monitoring is set at the factory to max. +27°C
and min. +15°.
By using the oor sensor, HC10B will now ensure that the oor temperature*) is
never higher than + 27°C nor lower than + 15°C. These values can be adjusted as
desired.
*) Temperature measured by floor sensor.
Limiting the maximum temperature in the oor is important when the heating is in-
stalled under a timber oor. Leading suppliers of timber oors prescribe a maximum
temperature of 27°C on the surface of their oors.

Brugervejledning - Generel information
A) Hvad kan termostaten
PTermostaten er en digital termostat til nøjagtig styring af elektrisk gulvvarme.
PTermostaten starter automatisk i Kvikstart = manuel drift
PTermostaten kan også lave tre typer Dag og natsænkning
B) VIGTIGT! Før gulvvarmen tilsluttes
PFor at sikre optimal levetid på gulvvarmen, skal det materiale gulvvarmen er
indstøbt i tørre i min. 28 dage inden varmen tændes.
PFørste tilslutning af termostat og gulvvarme skal foretages af en autoriseret
elinstallatør
PUdskiftning af en eksisterende termostat til en af samme type, er tilladt for
forbrugeren
PTermostaten må ikke tildækkes
C) Programmerne i termostaten
C1) Kvikstart
PTilslut og gulvvarmen kører
PTemperaturen er stillet på 21°C
LTemperaturen kan ændres med [q] eller [p]
Displayet viser den indstillede temperatur
PGulvføleren benyttes automatisk
C2) Nat og dagsænkning - programmer
PHC10B har tre forskellige dag og natsænknings programmer.
PDe kontrollerer hver især temperatur og tidsindstillinger til f.eks. en lav tempe-
ratur om natten og i løbet af arbejdsdagen. Resten af tiden, morgen og aften, er
temperaturen normal.
PFor hvert program gælder, at temperaturer og tider er deneret i forudindstil-
lingen/fabriksindstillingen. Tider og temperaturer kan indstilles efter behov.
Fabriksindstillingen fremgår af tabel 1 herunder.
PNat og dagsænkning sikrer minimalt strømforbrug. Under optimale forhold med
natsænkningen indstillet til min. 3°C, kan forbruget gå ned med 15%. Bespa-
relsen afhænger naturligvis af de specikke omstændigheder, og den måde
gulvvarmen benyttes på.
PMax. og min. begrænsningerne er aktive i alle tre programmer. Max: 27°C
Min.: 15°C.
Program 1: En fælles indstilling for mandag til fredag og en anden for lørdag og
søndag.
Program 2: Samme indstilling for alle ugens dage.
Program 3: Indstilling af hvert enkelt ugedag for sig.
Tabel 1: Fabriksindstilling af dag og natsænkning.
Tider og temperaturer kan indstilles efter eget ønske. Se under punkt 3.4) og 3.5).
Program 1: En fælles indstilling for mandag til fredag og en anden for lørdag og
søndag.
