Receiver Manual Override; Switching Sensitivity Option - ESI ESRTPRF User And Installation Instructions Manual

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 (Fig.7, page 24) on the receiver, which will then light
up with a green background.
After 2-3 seconds, press the M/A button ① (Fig.7, page
24), 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 (Fig.7, page 24). The receiver should now be
back in automatic mode, recieving commands from the
thermostat.

ed: ±0.2°C factory default setting, recommended for
