STEP 2: SET LETTERBOX MODE ON TRANSMITTER
On the transmitter, press rapidly 10 times (Confi guration Menu
M ) and check that the LED starts fl ashing.
Press rapidly 32 times (
32 ) and check that the LED confi rms at the end by fl ashing twice.
At this point, the transmitter is locked in LETTERBOX mode
(11)
.
STEP 3: SETTING LETTERBOX MODE ON THE KIT PANEL
Set dip-switch 1 in the ON position.
In this way, the LETTERBOX is enabled and the door open detection alarm function is disabled; the two functions
are mutually exclusive.
THERMOSTAT SETTING
With the thermostat function the video door phone can be used to control the boiler.
Normally, the thermostat function is not active.
Proceed as follows to set it:
Connect an external temperature sensor (e.g. Ref. 1430/50) to the video door phone.
Defi ne the connection to the boiler, which can be:
wireless, using a pair of ‘home automation buttons’ and a Yokis MTR2000ERP module,
wired (using Contact 2, suitably decoupled).
Activate the function.
CONNECTING THE TEMPERATURE SENSOR
The temperature sensor should be connected to the appropriate connector on the back of the video door phone
using the wire supplied as standard with the video door phone.
The maximum distance between the sensor and the video door phone is equal to 1m.
WIRELESS CONNECTION OF THE THERMOSTAT TO THE BOILER
Position Yokis MTR2000ERP relay near the boiler.
Choose two home automation buttons which will be used exclusively for controlling the relay connected to the
boiler.
The two chosen buttons MUST BE ADJACENT: e.g. 1, 2 or 2, 3 or 3, 4, and so forth up to 7, 8.
Connect the two buttons to the MTR2000ERP relay in wireless mode, defi ning the ON function to the fi rst button
and the OFF function to the second button (e.g.: 7= ON; 8=OFF).
WIRED CONNECTION OF THE THERMOSTAT TO THE BOILER
A wired connection (appropriately decoupled) can be used as an alternative to the wireless connection.
Open the Contact setup menu (see the respective paragraph) and set Contact 2 to the thermostat function.

(11) In LETTERBOX mode, the transmitter no longer accepts any controls, even reset. Exit LETTERBOX mode to
reactivate the transmitter to receive controls.
The procedure to close LETTERBOX mode on the transmitter is intentionally complicated to
prevent it from being inadvertently triggered by the knocking the letterbox fl aps and doors.
The procedure is the following: generate 10 rapid presses on any one of the inputs of the transmitter.
At this point, the LED of the transmitter will fl ash four times, but not consecutive: the fl ashes will be spaced
apart in a random manner. Press rapidly at each fl ash.
Only if the corresponding rapid presses are performed at the four fl ashes will the transmitter exit LETTERBOX
mode. It is indicated by a rapid fl ashing.
