• Association between the Klima LCD RF and the remote actuator
1. Activate the configuration of the remote actuator channel (refer to the related
instructions). The actuator will remain in configuration mode for a set time,
within which it must receive a configuration signal from Klima LCD RF.
2. Insert the batteries into the Klima LCD RF, respecting the polarity indicated
on the device (to access the battery compartment, remove the front shell by
pressing the tab on the bottom of the device).
After about 3 seconds, the Klima LCD RF starts the configuration procedure
(indicated by CNF showed on the display) followed by a short test procedure
(indicated by TST showed on the display) during which the Klima LCD RF sends
the on-off-on-off sequence to the actuator.
3. Once the test phase has elapsed, the remote actuator is ready to receive on and
off signals from the thermostat.
How to associate another remote actuator:
1. activate the actuator channel configuration
2. press simultaneously and for at least 3 seconds the keys “ ” and “ ” to
access advanced programming
3. the display shows
RF
. Wait for 2 seconds without pressing any key
4. the thermostat sends a configuration signal to the actuator and then activates
the test phase, which ends when the actuator is associated with the thermostat.
Note: The Set Klima LCD RF is sold already configured.
• Indications for positioning
Install the thermostat at a height of about 1.5 m above the floor, away from direct
sunlight, away from doors, windows, heat sources, locations with excess or total lack of
ventilation.
The actuator is usually placed near the boiler to be commanded.
Attention: the maximum distance between the Klima LCD RF and the remote actuator
is about 50m in free field. This value is reduced if there are obstacles in the middle (for
example walls in reinforced concrete).
REFERENCE STANDARDS
EU CONFORMITY DECLARATION
Vemer declares that the device is in compliance with the Community
Directive 2014/53/EU (RED) with reference to the following standards:
• ETSI EN 300 220-1 • ETSI EN 300 220-2 • ETSI EN 301 489-1
• ETSI EN 301 489-3 • EN60730-2-9

Minimum settable setpoint -
L0
It’s the minimum value settable as setpoint.
Settable values: 2 ÷

Maximum settable setpoint -
HI
It’s the maximum value settable as setpoint.
Settable values:

if connected to a cooling system
Antifreeze temperature - Toff
- (only in heating)
Minimum temperature maintained with instrument off.
Settable values: 1 ÷ 10 °C or --- (excluded function)
Regulation type -
REG
- (only in heating)
0
= on/off with settable differential
P8
= proportional with band 0.8 °C and period 8 minutes
P15
= proportional with band 1.5 °C and period 15 minutes
tP
= (to be used only if associated with radiator valves) the valve opens
proportionally to the difference between the setpoint and the measured
temperature
Differential -
d0.3
- (only for on/off regulation)
Differential (or hysteresis) for temperature regulation.
Settable values: 0.1 ÷ 1 °C
Password for keypad lock -
PAS
Set a value between 001 and 999 to activate the keypad lock.
Set “---” to disable the lock.
If the keypad lock is active, pressing one key
LoC
appears and the password is
required. If it’s properly inserted the keyboard is unlocked for the next 30 seconds.
rF communication test -
RF
To activate the communication test between the thermostat and the actuator, press any
button. During the test, the thermostat sends the sequence of on and off commands
with a distance of 3 seconds from each other; the display shows
tSt
. The test lasts a
maximum of 10 minutes, but it can be stopped first by pressing any key.
The “Advanced Programming” menu is divided into two parts: configuration of RF transmission (
rF
) and programming of operating parameters (PR). To access the advanced program-
ming, press simultaneously and for at least 3 seconds the keys
and
until the display shows
RF
. At this point choose within 2 seconds, if to activate the
RF
configuration
procedure (see ‘How to associate another remote actuator’ in box 4) or access the programming of
PR
parameters. If no choice is made within 2 seconds, you automatically access
the RF configuration.
Note: the passage from a menu to the next occurs after 3 seconds
without keys pressing. Press simultaneously the keys
and
for at least 3 seconds to force the exit from the menu.
Note: when the thermostat is in heating mode (winter) and is off, it regulates
according to the
Toff
antifreeze temperature in order to prevent freezing of the
system.
Toff
can have values from 1 to 50 °C or be excluded; in this case any minimum
temperature is guaranteed.
Occurs in case of probe failure.
In this case the thermostat sends the actuator the off
command and the system remains off until the fault is reset.
Occurs for the following values of measured temperature:
t < 0 °C
t >50 °C

Configuration -
CNF
Indicates the configuration signal sending
(coupling between Klima LCD RF and actuator) in
progress. Once configured, Klima LCD RF
activates a test cycle.
Note: before starting the configuration
it is necessary to activate the channel
configuration on the receiver.
Test -
TST
The test cycle allows you to verify the correct
configuration between Klima LCD RF and the
actuator. The on-off-on-off sequence is started
and when it is ended the Klima LCD RF
resumes normal operation.
