Connecting The Room Thermostat; Accessories Not Included In The Supply - Baxi LUNA DUO-TEC IN+ Instruction Manual For Users And Fitters

11.3 CONNECTING THE ROOM THERMOSTAT

The connections in terminal block M1 are high voltage (230 V). Before making connections, make sure the appliance is
disconnected from the power supply. Respect polarity L (LIVE) - N (NEUTRAL).
To connect the Room Thermostat to the boiler, proceed as described below:
• switch off the boiler;
• access the terminal block M1;
• remove the jumper from the ends of contacts 1-2 and connect the wires of the Room Thermostat;
• switch on the boiler and make sure the Room Thermostat works correctly.

11.4 ACCESSORIES NOT INCLUDED IN THE SUPPLY

11.4.1 EXTERNAL SENSOR
Connect the wires of the external probe to the
terminals 4-5 of terminal block M2 as shown in
the figure to the side and following the instructions
provided with the same probe.
When the external probe is connected, adjustment
of the heating flow temperature depends on the
devices that interface with the boiler, as described
below:
• CONNECTION OF THE ROOM THERMOSTAT
WITHOUT REMOTE CONTROL
The Kt curve is set manually at the keys
the control panel of the boiler.
• CONNECTION OF THE REMOTE CONTROL
WITHOUT ROOM THERMOSTAT
When the Remote Control is installed (section "INSTALLING THE REMOTE CONTROL ON THE WALL"), adjustment of the
heating flow temperature depends on the K REG curve, the "KORR" coefficient (influencing the room temperature) and the
temperature (TAMB) set manually at the keys
• CONNECTION OF THE ROOM THERMOSTAT AND REMOTE CONTROL
If both the devices, the Room Thermostat and the Remote Control, are connected to the boiler, adjustment of the heating flow
temperature depends on the curve set for each device as described above.
1) SETTING THE "Kt" CLIMATE CURVE WITH ROOM THERMOSTAT (TA) AT THE BOILER CONTROL PANEL
When the external sensor is connected to the boiler, the electronic board adjusts the flow temperature calculated according to the
set Kt coefficient. Select the required curve by pressing
most appropriate one (00 to 90).
IMPORTANT: the kt curve can be adjusted at the boiler control panel only when the Remote Control is disconnected from the
boiler.
