The RTM-03 is a temperature controller
designed for operation of electrical loads
(such as radiators or resistance floor heating
systems) in relation of the ambient temperature
detected by an NTC sensor. The product can
control the connected power loads according to
the temperature set with the control potmeter
on its front panel, with the setting range from
-10ºC to +90ºC. The other potmeter can
select one of 10 available hysteresis settings
of the temperature controller (from 0.25ºC
to 2.5ºC). The product requires an external
NTC-03 temperature probe to work properly.
The temperature probe must be purchased
separately. The probe wiring is 3 m and can
be extended by up to 50 m with a 0.2 to 2.50
mm
2
core wire. Do not connect several probes
to the same wire.
Connect this product to a single-
phase power system according to
applicable electrical and safety
standards and regulations. See
this Manual for the wiring instruc-
tions. Installation, wiring and
adjustment/setting shall only be
done by qualified electricians
who have read and understood this User Manual
and the functions of the product. Do not open or
otherwise disassemble the product housing; other-
wise the product warranty will be void and an elec-
trocution hazard may occur. Prior to installing and
wiring this product, make sure that the wiring to be
connected is not live. The conditions and methods
of transport, storage and operation of this product
may affect its performance. Do not install the prod-
uct if any of its components are missing, the product
is damaged or deformed in any way. If any malfunc-
tions are found, consult the manufacturer.
CAUTION
Relay output terminals (11; 12; 14)
Do not dispose of this device with other
waste! In order to avoid harmful effects on
the environment and human health, the
used device should be stored in designated
areas. For this purpose, you can dispose
of household waste free of charge and in
any quantity to a collection point set up,
as well as to the shop when you buy new
equipment.
