APPLICATION
INSTALLATION, OPERATION
DIMENSIONS
1. Isolate from power the wiring system to be
connected with this product with its circuit
breaker, overcurrent device or disconnec-
tor, as applicable.
2. Use a suitable tester to verify that the iso-
lated power input wiring is not live.
3. Install the RTM-03 on a DIN-Rail in the re-
spective switchboard.
4. Connect the wiring to the terminals, see
the applicable wiring connection diagram.
5. Turn on the power of the connected wiring
system.
The product is ready for use once properly
installed and wired. The product monitors the
ambient temperature of the external NTC sen-
sor (probe). If the ambient temperature is below
T - ∆T, the temperature controller switches the
output relay ON (make outputs 11-14), which
powers on the wired power load (e.g. an elec-
tric radiator). The power load will remain on
until the ambient temperature is T+ ∆T. The
temperature hysteresis, which is user-settable
between 0.25°C and 2.5°C, eliminates too fre-
quent switching of the relay within its switching
threshold tolerance. The auxiliary input can be
wired to an external control timer or control
switch for periodic reduction of the ambient
temperature by 5°C (the so-called Night-Time
Heating mode).
NTC sensor wiring indication:
• Wiring shorter / sensor missing: the green
LED pulses 1/second;
• Sensor wiring OK: the green LED stays on.
