Communication Fail Safe Modes
RECEIVER FAIL SAFE MODE
Should your receiver enter the Fail Safe Mode this will be conveyed by the LED indicator
going solid amber. This will only happen if the receiver has not received a signal from the
AS2-RF for more than 60 minutes. Some basic instructions are detailed in the previous
section and on the inside of the receiver flap for the emergency use of the relay/heating
during this mode.
To resume normal operation please use the following procedures;
Press the 'Warm/Cool' button on the front of the AS2-RF for 5 seconds, or until the display
illuminates, then press again to send a signal to the receiver, if successful this will be
indicated by the LED on the receiver changing from amber to either red or green.
Or
Check and replace, if necessary, the 3 x AA batteries in the AS2-RF transmitter, then follow
the process above.
If the processes above fail to regain normal operation then please consult your heating or
service engineer for further assistance.

OPERATING MODES

During normal operation the receiver will indicate the boiler status through the colour of its
LED, please refer to the RECEIVER STATUS INDICATOR LED on page 12.
The AS2-RF also uses a combination of LED and LCD displays to assist the user to gain
maximum benefit from the thermostat. During normal operating period, where no user
intervention has occurred, the AS2-RF will power down to maximize battery life. To 'wake'
the AS2-RF press the Warm/Cool for 5 seconds, the displays, both LED and LCD will now
illuminate and will stay lit for a period of 8 seconds after the last button press.
