Electrical Connection; Heating Operation - Dimplex TRFB 150 Mounting And Operating Instructions

3. Electrical Connection

The hardwired electrical installation must be provided
with an all-pole disconnecting device with a contact gap
of at least 3 mm (e.g. automatic circuit-breaker).
If the heater is installed in a bathroom, it must be pro-
tected by a residual current device (≤ 30 mA)!
In addition to the wires for the mains connection (L -
brown, N - blue) a control wire (black) for external tem-
perature setback, e. g. via a timer or a pilot device of the
"ecocomfort" range with programming cassette RMT 1 is
provided.
The control wire need not be in phase with the mains
connection.
Due to its double-insulated design, the heater requires
no earthing conductor.
If the supply cord of this appliance is damaged it must be
replaced by the manufacturer or its service agent or a
similarly qualified person in order to avoid a hazard.
4. Automatic Temperature Setback
The black control wire serves for automatic temperature
setback, e.g. via an external timer or a pilot unit of the
"ecocomfort" model range.
More detailed information is contained in the operating
manuals of the "ecocomfort" model range or the pro-
gramming cassette RMT 1.

5. Rails for Towels/Garments
The heater is supplied with 3 rails. Towels and garments
can be placed on these rails for drying. The ladder de-
sign of the rails maximises capacity for hanging damp
towels and clothes.
Attention: Only damp – not wet – garments should be
placed over the rails for drying.

6. Heating Operation

The heater has 2 separate heating modes:
•
Radiant heating via the heated surface,
•
Fan heater. The heat is given off by a fan with a
separate heating element, via the air outlet slots
on the bottom of the appliance.

6.1 On/Off Button
Button A is used to switch the heater on and off.
Power-On indicator light A1 is illuminated while
the heater is switched on.
The radiant heating system is controlled via ther-
mostat B.
Fan operation is activated via separate buttons (C
or D), see Section "6.3 Fan Operation".
6.2 Thermostat
The desired room temperature can be set by turn-
ing thermostat dial B.
The thermostat switches the radiant heater on
and off as a function of the room temperature and
the value pre-set on the thermostat dial.
The lowest setting on the thermostat is a freeze
protection function (dial at symbol ∗). In the freeze
protection mode, the thermostat turns on the radi-
ant heater at an ambient temperature of approxi-
mately 7°C.
Higher temperature values can be pre-set on a
scale from "1" to max. "10" (approx. 29 °C).
The fan operation is not regulated by the thermo-
stat.
6.3 Fan Operation
6.3.1 Fan Heater
For rapid heating, button C can be used for addi-
tionally switching on the integrated fan heater for
a pre-set period of time. Three time settings are
possible:
Press button once (½h) –30 minutes ,
Press button twice (1h) – 60 minutes,
Press button three times (2h) – 120 minutes.
Press the button once again to switch off the fan
heater.
During the pre-set time period, the room will be
heated at maximum heat output, irrespective of
the thermostat setting.
