The RTM-20 temperature digital regulator
is designed for load control (e.g. heaters,
floor heating systems) in dependence of
ambient temperature near an external
NTC sensor. It is possible to control
temperature within the range of +5°C ÷
+60°C.
The external NTC-03 probe is needed
for a correct device operation. The is
not part of the set and it is necessary to
purchase it separately. The probe lead is
3 m in length. It is possible to extend it up
to 50 m with 0,2 ÷ 2,5 mm2lead. Do not
join the probes.
CAUTION:
Before installing
the device in the
switchboard
or starting the
system operation
in order to
programme it,
the battery security
separator should
be removed
against
discharging.
The device should be con-
nected to a single-phase
system according to current
standards. The device con-
nections will be described in
this manual. Only qualified
electricians are allowed to
mount, connect and adjust the module. It is
necessary to read this manual before the de-
vice mounting. Do not disassembly the device
casing or you will lose any warranty rights and
expose yourself to the electric shock hazard.
Before mounting operation make sure of di-
sconnecting the connection wires from the
electric network. Use a cross-head screwdri-
ver of 3.5 mm diameter to mount the device.
The regulator should be carried, stored and
used in an appropriate way. Do not mount the
device in case of any regulator parts lack, da-
mage or deformation. In case of malfunction
please notify the manufacturer.

DATE SETTING
- Current date setting; entry after pressing OK;
YEAR - choose adequate year with cursors confirm with OK, range of
years: 2000÷2099;
MONTH - choose month with cursors confirm with OK;
DAY - choose day with cursors confirm with OK; the system has a protec-
tion against introducing incorrect parameter of a day for a given month ( it
takes into account leap years and it automatically calculates the day of the
week on the basis of an arranged date);
Confirmation causes movement to a date setting window and set-up of cur-
rent summer/ winter time - if the option is arranged.
It is possible to exit every sub- menu window in any moment without
saving settings by pressing the button or .
