Installation and Operation Manual
Description
The Room Unit communicates with the RF Receiver on
an 868MHz Radio Frequency (RF) band to control the Heat
Pump System Controller. Neither product will communicate
with other RF products that use different frequencies or
communication protocols.
Note: The RF link between the Room Unit and RF Receiver
in system packs is pre-configured at the factory and
therefore these components SHOULD be installed at the
same site. This makes the installation process fast and easy,
but if products from individual system packs are separated,
or mixed with other pre-configured system packs during
installations please refer to section 4. Binding / Rebinding
Procedure to bind the desired units together and allow them
to communicate with each other.
