FAQ AND TROUBLESHOOTING
How reliable is 2-way RF communication?
The 2-way RF communication (also known as wireless communication) used by
Honeywell is extremely robust and reliable. When installed correctly the Signal
Strength test feature allows the Installer to locate the system components where
mutual signal reception is strong. During communication, signals are sent several
times to ensure receipt, and if any message is garbled, the error detection software
recognises this and ensures the message is repeated again.
What do I do if RF communication is lost?
Follow the steps in the Troubleshooting Guide on the next page. The most likely
cause for loss of communications is the CS92A batteries running low on power. This
will be indicated on CS92A, as described on page 19. Simply replace the batteries
(as shown on page 19) and wait a few minutes for communications to become re-
established.
If this does not resolve the problem it may be that the RF signal path between
the ST9120C and the CS92A is blocked by a metal object. Check the direct path
between the two devices and reposition any object that may be blocking the signal,
or move the thermostat.
How do I know when to change the batteries in the CS92A
cylinder thermostat?
If the CS92A batteries need changing, ST9120C will show the message ‘SENSOR
LOW BATT’ and the tap symbol
will flash. . You can confirm this by pressing the
CS92A button, whereupon the red light will give a brief flash every second to indicate
a low batter y state. It is important to change the CS92A batteries as soon as the low
battery condition is indicated, as reduced battery power may affect the RF signal
strength and impair RF communications.
