Receiver Manual Override

It is possible to operate the receiver manually. This may be
necessary where, for example, the batteries in the Thermostat
(Transmitter) are depleted and therefore the heating cannot
turn on or off.

To engage the manual override, press the MANUAL button

2

(See page 10) on the receiver, which will then light up with a
green background.

After 2-3 seconds, press the M/A button

1

(See page 10),

which may be ON (red background) or OFF. This will manually
override the status of the receiver. If ON, the heating will turn
OFF (M/A red light goes off). If OFF, the heating will turn ON
(M/A red light comes on).

N.B. It is important to remember that the automatic control

of the receiver is now off and the receiver will only
respond to manual operations.

To return to automatic mode, press the M/A button

1

(with or

without the red light on) and then press MANUAL button

2

(See page 10). The receiver should now be back in automatic
mode, recieving commands from the thermostat.
