Fenix Therm 105: Getting started

Getting started: Fenix Therm 105

Getting started

After installation, wait 2-4 weeks

before starting the underoor heating.

Precisely how long you wait depends

on the type of oor you have and the

EN

instructions for the oor putty. Then

increase the heat gradually.

In order to adapt the underoor

heating system to your own heating

requirements as much as possible, it

is important that you read the entire

manual.

How the thermostat works

This section describes all you need to

know about how the thermostat works

and how you set it.

On/o switch

Temp. control

Turning o and on

The heating is not controlled in stand-

by mode. Depress the on/o switch

for a second to access stand by mode.

Return to normal mode by once again

depressing the button for a second.

26

Control functions

The thermostat

can regulate the tempera-

ture in three dierent ways. This enables

the comfort temperature and any ooring

temperature requirements to be combined.

How the settings are adjusted is descri-

EN

bed on the next page

.

Floor thermostat (F) - A sensor in the oor

measures the temperature and then regu-

lates the heating accordingly.

This is the

factory setting.

Room thermostat (R) - The thermostat

has built-in sensors for measuring the

rooms temperature and controlling the

heating.

Room and oor thermostat (R&F) - The

built-in sensor regulates the room tem-

perature and the sensor in the oor func-

tions as a oor temperature limiter. The

limitation can be set to between 25°C

and 45°C. The factory setting is 35 °C.

Important

In rooms with large windows that are ex-

posed to solar insolation, we recommend

the Room and oor thermostat function.

In rooms with wooden ooring, the

Room and oor thermostat function

must always be used.

27

The adjustment of the regulating

function, must be done by a qualied

electrician. The knob and the front rst

have to be removed. Disconnect from

power supply before removing.

Then slide the control to the required

position using a small screwdriver.

The overheating protection is adjusted here.

The regulating function is adjusted here.

R&F - Room and oor thermostat

Temperature

Regulating function

The thermostat regulates the

temperature via a sensor in the oor

that measures the temperature and

EN

regulates the heating accordingly.

Set the temperature required

Change the oor temperature by turn-

ing the knob. Min. position on the con-

trol corresponds to 10 °C, max. position

corresponds to 45°C. An appropriate

setting is usually between 2 and 3.

The temperature does not stabilise

until the underoor heating system has

been on for a few days. It might then

be necessary to adjust the thermostats

setting.

Indication

The colours on the on/o switch show

the current status for the thermostat.

Red light - the thermostat is on and the

underoor heating is activated.

Green light- the thermostat is on and

the underoor heating is switched o.

29

Delay between turning o and on

There is a built-in delay in order to

avoid unnecessary wear and tear on

internal components and to extend

the life of the thermostat. If you raise

the desired temperature so that the

thermostat comes on, and then lower

it shortly afterwards, it takes four min-

utes before it goes o again.

Key lock button

When you have found a suitable set-

ting for the temperature you can lock

the knob. This prevents the control

being changed accidentally.

See illustration below. First remove

the knob. Then move the two plastic

parts so that they dene the interval

required. Replace the knob.
