4.1 Connecting to Cylinder unit
* Before installation, be sure to turn off the main power supply.
Remove the two screws that hold the front panel, and remove the panel.
Screws
(2 positions)
Front panel
If the removed front panel is set aside away from the indoor unit, ensure the relay
connector on Main remote controller is disconnected.
Test wireless communication between the wireless remote controller and the wireless
receiver.
(See “6.4 Communication Test” in “6. Setting wireless remote controllers” in this manual .)
Position the wireless remote controller in an appropriate place.
(See "4. Before Operation" in OM.)
To set the wireless remote controller as a room sensor that monitors room temperature,
see "Main remote controller Options" in IM.
Use the main controller to set the ecodan system to the room temp. ( ) mode.
When the ow temp. ( ) mode or the compensation curve ( ) mode is selected, the
wireless remote controller will operate as a thermostat. (See “Main remote controller” in
IM.)
When the remote controller set as a room sensor runs out of battery or gets a
communication error during room temp. mode, the room temp. mode will auto-
matically switch to the compensation curve mode.
The room temp. mode will be restored by battery replacement or solution of com-
munication error.
Installation and setting of the wireless remote controller is complete. To set additional
wireless remote controllers, repeat Step to .
