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
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.

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
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.
