Fire place function
This function is designed to be used when you re-
quire high comfort on your floor even though the
room is already heated, for example, when you
fire up a wood burning stove. When this function
is enabled, it controls the room thermostat at 50 %
heat (default) to maintain heat in the floor surface.
The controlled output is adjustable from 5-100%.
The operation is time controlled over 1-99 h or is
continuously on. (default 16 hours)
Enable the function as follows:
1. Press
Set
until flashes, confirm with
Set.
2. Press the right arrow until
FiPL
(Fire Place
Function) appears in the display, confirm
with
Set
.
3. Select
ON/OFF
using the right/left arrow,
confirm with
Set
.
4.
16 hours
(16 hours) flashes in the display.
Adjust the right/left arrow where neces-
sary. Confirm with
Set
.
5.
50%
(controlled output) flashes in the
display. Adjust the right/left arrow where
necessary. Confirm with
Set
.
When the fire place function is enabled, the dis-
play switches between showing normal mode,
hours remaining (e.g. 16 h), and controlled out-
put (e.g. 50 %). When the set time has counted
down to zero, the room thermostat returns to nor-
mal operation.
An enabled fire place function overrides any possible
week program. Enabled setback or activated hol-
iday function overrides the fire place function.
By-pass function
The By-pass function is primarily designed for use
when the heat source comes from a heat pump.
The function means that one (or more) room ther-
mostats open its circuit by force when the other
room thermostats close their circuits.
Depending on the required function, you can ei-
ther choose time-controlled bypass or a bypass
that is constantly activated until some other cir-
cuit opens.
Time-controlled bypass keeps the bypass circuit
open for 22 minutes, then turns the circuit off.
The By-pass function is enabled as follows:
1. Press
Set
until flashes, confirm with
Set.
2. Press the right arrow until
BYPS
(By-pass)
appears in the display, confirm with
Set
.
3. Select ON using the right arrow, confirm
with Set. ON and the clock symbol flash
in the display indicating that the time-con-
trolled by-pass has been selected.
Press the right arrow if a constant by-pass is
required. The clock symbol will disappear
indicating that a constant by-pass has been
selected.
4. Confirm the selected function with
Set.
Temperature range limits
It is possible to limit the room thermostats' ad-
justable temperature range. This function is use-
ful in apartment buildings, for example, where
landlords wish to restrict the ability of residents
to control the room temperature within a certain
temperature range, such as 18-22 °C. If you at-
tempt to change the temperature outside the set
temperature range, the room thermostat shows
Min. and Max. values.
The function is enabled as follows:
1. Press
Set
until flashes, confirm with
Set.
2. Press the right arrow until
RATR
(Restricted
allowed temperature range) appears in the
display, confirm with
Set
.
3. The lowest temperature in the temperature
range flashes, set the required minimum
temperature using the right/left arrow,
confirm with
Set
.
4. The highest temperature in the temperature
range flashes, set the required maximum
temperature using the right/left arrow, con-
firm with
Set
. The display returns to show
RATR.
5. Repeat the above for the other room ther-
mostats that are to have a restricted temper-
ature range.
