BasicPlus
Floor Heating Room Thermostats

Application

FH-CWT FH-CWD FH-CWP

The BasicPlus room thermostats are used for
room temperature control in water based oor
heating systems.
By controlling the room temperature in accord­ance with the temperature desired by the user,
the room thermostats provide optimal energy
savings as well as optimal thermal comfort.

The room thermostats are available in three ver­sions:

FH-CWT Room Thermostat (with dial)

By turning the dial to the desired set-point
temperature optimal thermal comfort in the
room is achieved. In addition to temperature the
thermostat setting scale includes a frost symbol,
allowing for minimal energy consumption, while
keeping the room from freezing.
LED’s display the function of the thermostat:

• green light: the thermostat is ON, but without
heat demand.

• red light: the thermostat is ON and there is
heat demand.

FH-CWD Room Thermostats (with display)

In addition to room temperature control, the
FH-CWD can be equipped with a oor sensor,
thus allowing for control of maximum oor
temperature and reducing risk of overheated
and damaged oors. For specic maximum oor
temperatures, please refer to recommendations

from oor suppliers.

Using the Frost Protection Mode instead of
turning the thermostat OFF may protect against
damages due to low temperatures. The room
temperature will be maintained around 5° C.

FH-CWP Room Thermostat (programmable
with display)

Two available timer programs are allowing tem­perature setback or complete turning o the heat
supply during selected periods.
The ON / OFF Timer Function enables to pro­gram the thermostat for one period with heating
turned OFF and one period with heating turned
ON per day. During the ON period the thermostat
will regulate in relation to the set temperature
and TIMER ON will be shown in the display. Dur­ing the OFF period, the heating is o, and TIMER
OFF is shown in the display.
The Advanced Programmable Timer Function
allows to set a timer controlled program for auto­matic change between comfort temperature and
energy saving setback temperature, when stand­ard room comfort temperature is not required.
The Advanced Programmable Timer Function al­lows for 4 dierent periods / 5+2 days per week.
