Binding The Wireless Thermostat And Rf Receiver; Communication Loss - Hitachi ATW-RTU-08 Installation And Operation Manual

Binding the Wireless thermostat and RF Receiver

3 BINDING THE WIRELESS THERMOSTAT AND RF RECEIVER
By default the thermostat is already linked to the RF receiver. For
these reason there is no need to perform binding procedure in
case it is only required one wireless thermostat at the installation.
The binding operation described below is required if:
• Any of the system components (Room Thermostat or
RF Receiver) are replaced. Go to step 1.
• The RF Receiver has incorrect or no binding data stored
(e.g. when pre-bound system pack components have been
mismatched). Go to step 1.
• When adding a second wireless thermostat. Go to step 2.

2 Hold button on RF Receiver for 5 seconds. Led will flash for
1 seconds ON and 1 second OFF.

communication fails makes the RF receiver to enter into alarm
state.
• If there is a communications fault between the RF Receiver
and the Room Thermostat.
• If there is a fault in communications between the YUTAKI

• If there is one Room Unit installed and communications is
lost with that zone.
• If there is more than one Room Unit installed, as in multi-

one zone.
• If there is more than one Room Unit installed, as in multi-
zone systems for example, and communications is lost with
both zones.
